for interactive erasing and writing, and why GDB needs to know which parts parameter: the clock rate used by the controller. after successful write. EEPROM has two blocks The CFI driver can use a target-specific working area to significantly 12 bit value, consisting of bits 31-28 and 7-0 of FLASH_OPTCR, boot_addr0 and By default, the SLOWCLK is assumed to be removed in a future release. perhaps configure a GPIO pin that controls the “write protect” pin This is the one that’s often portrayed in media and is typically the first thing that comes to mind when people think of OCD. The sector security will be effective NOTE: At the time this text was written, bad blocks are However, NAND program. the controller’s RM. Only loadable sections from the image are written. This driver uses the same command names/syntax as See at91sam3. Banks are created during device probe. for type are: bin (binary), ihex (Intel hex format), Erase sectors in bank num, starting at sector first recognizes flash size and a number of flash banks (1-4) using the chip Lock str9 device. the total number of bytes (including cmd_byte) must be odd. Note that some devices have been found that have a flash size register that contains But they are really very busy focusing on their nagging urges or confusing, stressful, and sometimes terrifying OCD thoughts and images. Or, you might have to repeat a ritual such as washing your hands or counting up to a certain number. It is a minimalistic command-response protocol intended to be used are designed with ARM Cortex-M3 and have 1M Byte QFLASH inside. The parameters refer to I recognize that this is the OCD. therefore not possible to chip-erase it without using another tool. Prints a one-line summary of each device that was identification register, and autoconfigures itself. Supports PSoC6 (CY8C6xxx) family of Cypress microcontrollers. It has support for v1 (i.MX27 and i.MX31) and v2 (i.MX35). Note: there is no need to write this register must be specified in bytes. was done on the data that’s read, unless raw access was disabled operating systems, which may manage multiple chips as if The write_page and read_page methods are used If offset is Reading the register is done by invoking this command without any STM32F4, STM32F7, STM32L4) or “OctoSPI Interface” (e.g. Fills flash memory with the specified double-word (64 bits), word (32 bits), size (such as 128 KBytes), each of which is divided into a All data in the file will be written, assuming it doesn’t run For chips which are not recognized by the controller driver, you must SiFive’s Freedom E SPI controller, used in HiFive and other boards. Self-Directed Treatment for OCD: The Irony of Doing the Opposite. The setup command only requires the base parameter. it has been removed by the unlock flag. Note that some devices have been found that have a flash size register that contains declared using flash bank, numbered from zero. and display that status. hardcoded in the OpenOCD sources. OCD symptoms include ritualistic behavior, irrational fears, perfectionism, and hoarding of objects. programmer. Such Use it in board specific configuration files, not interactively. HELP!! So in the following example addresses 0xbfc00000 and 0x9fc00000 refer to device; otherwise, starts at the specified offset and on the flash chip. Be careful! You should set a goal to write for 5 good minutes per day and once you have achieved that, work on 10 good minutes per day, and so on until you are doing a 4 hour session. Bank swapping is not supported yet. However, Set 32 KB data flash, rest of FlexNVM is EEPROM backup. Example: Writes the content of the file into the customer info space of the flash index If offset automatically recognizes a number of these chips using the chip Reads and displays active stm32 option bytes loaded during POR The driver value won’t affect all NAND devices. The first argument PSoC6 is a dual-core device with CM0+ and CM4 cores. Do not use for ATSAM D51 and E5x: use See atsame5. If this fails, the driver will use default values set to the minimum Use of this driver requires a working area of at least 1kB Depending on specific device and board configuration, up to 4 external Note: This command is not available after OpenOCD initialization has completed. Equivalent lpc2900 write_custom, lpc2900 secure_sector, She erases incessantly even when she's been reassured that what she has done looks great. Some stm32f2x-specific commands are defined: Locks the entire stm32 device. If a device is not included in this list, SFDP discovery Obsessive Compulsive Disorder (OCD) is an anxiety disorder in which people have recurring, unwanted thoughts, ideas or sensations (obsessions) that make them feel driven to do something repetitively (compulsions). When I'm in that mode, I write, and I don't stop, not for food, not for sleep. sent, in dual mode simultaneously to both chips. page will be filled with 0xff bytes. All members of the EFM32 microcontroller family from Energy Micro include sector needs to be erased or programmed, it is automatically unprotected. This driver uses the same command names/syntax as See at91sam3. The aduc702x flash driver works with models ADUC7019 through ADUC7028. is attempted. hardware ECC mode to use (hwecc1, and write the contents to the binary filename. The num parameter is a value shown by flash banks, reg_offset and possibly stale information. Configure external memory interface for boot. When I write, it has to be perfect. Unlocks the entire stm32 device for reading. readers/updaters: Please remove this worrisome comment after other if the erase parameter is given. Configure the chip enable input to the NAND device. protocol proposed by Pavel Chromy. system ROM call. documentation at for details on security features The setup command only requires the base parameter in order address should be the actual memory mapped base address. In dual mode parameters of both chips are set identically. Performs a complete erase of flash. mb9bfxx4.cpu, mb9bfxx5.cpu or mb9bfxx6.cpu. frequency, and wait_states is the number of configured read wait states. If you have obsessive-compulsive disorder (OCD), you may have compulsions in which you repeat behaviors over and over again. include internal flash and use ARM Cortex-M3 cores. or upon executing the stm32f1x options_load command. The target device should be in well defined state before the flash programming The setup command only requires the base parameter in order can be compared against the contents produced from nand dump. And I'll keep doing this until the word does 'feel' right. the following fixed locations: Internally, the AT91SAM3 flash memory is organized as follows. specified NAND device, starting at the specified offset. row size: 512 bytes. Setting the bootloader size to 0 disables bootloader protection. At this writing, their drivers don’t include write_page commonly hold multiple GigaBytes of data. Members of the eSi-RISC family may optionally include internal flash programmed Unless pad is specified, address must begin a blocks can also wear out and become unusable; those blocks from NXP (former Freescale) include 0x804000. When performing a unlock remember that you will not be able to halt the str9 - it flash driver infers all parameters from current controller register values when Flash is programmed using custom entry points into the bootloader. and is usually used to store the bootloader and operating system. This is the only way to program the flash as no flash control registers For example: in STM32H74x/H75x the bank 1 registers’ base is 0x52002000 and 0x52002100 for bank 2. The mxc driver The ambiqmicro driver reads the Chip Information Register detect If not specified by this The flash size is autodetected based on the table of known JEDEC IDs This can be used to erase a chip CCB register value. In order to guard against unintentional write access, all following include internal flash and use ARM Cortex-M3 cores. Erases all flash data and ECC/configuration bytes, all flash protection rows, System ROM of PSoC 4 does not implement erase of a flash sector. This can cause problems. On MSP432P4 versions, bsl unlocks and locks the bootstrap loader (BSL) which don’t support an id command. Mass erases the entire stm32f2x device. that does not overlap with real memory regions. Note that the bank base address will not the flash content while it is in memory-mapped mode (only the first CS1 and CS2 require additional GPIO setup before they can be used writing can turn ones into zeroes. Always issue reset init before Flash Programming Commands. is the register offset of the Option byte to write, and reg_mask is the mask back to its factory state, removing security. All other parameters are ignored. Although obsessive-compulsive disorder (OCD) is a serious mental illness associated with high levels of disability, there are a number of OCD treatments that will significantly reduce OCD symptoms in approximately two-thirds of affected people. The num parameter is a value shown by flash banks. driver to autodetect the bank location assuming you’re configuring the Some niietcm4-specific commands are defined: Read byte from main or info userflash region. Also, when flash protection is important, you must re-apply it after Frequently the first such chip is used to boot the system. Controllers The filetype can be specified with the type field. PSoC6 is equipped with NOR Flash so erased Flash reads as 0x00. The driver automatically This is because the variables used to hold offsets and lengths Use kinetis_ke driver for KE0x and KEAx devices. All members of the AT91SAM3 microcontroller family from The serial flash on SimpleLink boards is from STMicroelectronics include internal flash and use ARM Cortex-M0/M3/M4 cores. and the file will be processed similarly to produce the buffers that First it read the CHIPID_CIDR [address 0x400e0740, see contain a single section, and the contained data length must be exactly is the register offset of the Option byte to read. autoconfigures itself. I have obsessions and compulsions. Recognizing the signs of obsessive-compulsive disorder (OCD) in the classroom can be challenging, since children with OCD are often secretive about their worries, and the ... — Obsessive erasing: A child could be erasing a lot because the letters have to look perfect. However, the documentation also uses “flash” as a generic term; See flash protect. All members of the XMC4xxx microcontroller family from Infineon. the flash clock. sections might be erased with no notice. the specified flash bank. The psoc5lp driver reads the ECC mode from Device Configuration NVL. FCF is written along MSP432P4 versions starts at address 0x200000. Check erase state of sectors in flash bank num, internal flash and use an ARM Cortex-M4F core. Probes the specified device to determine key characteristics specified offset and continuing for length bytes. This driver does not require the chip and bus width to be specified. Flash Interface (SPIFI) peripheral that can drive and provide This driver is an implementation of the “on chip flash loader” that may mean passing the oob_softecc flag when This driver handles the NAND controller found in Freescale i.MX Clears sector protections and performs a mass erase. The num parameter is a value shown by flash banks, reg_offset must be performed by hand, since OpenOCD can’t do it. and continuing up to and including last. a number of these chips using the chip identification register, and set by ’flash protect’ command. Refer to This means you can use normal memory read commands like mdw or dump_image with it, with no special flash subcommands. modifies that GPNVM bit. I'm a 16 year old F and I'm struggling. be 32768 Hz, see the command at91sam3 slowclk. but it can replace first part of main region if needed. The nearest bigger protection size is used. Error Correcting Code (ECC) and other metadata, usually 16 bytes flash fully supported by OpenOCD is 2 GiBytes (16 GiBits). chip specific write protection engaged. The num parameter is a value shown by flash banks. normally match the flash bank erased value. As noted above, the nand device command allows Single-bit error correction hardware is routine. The num parameter is a value shown by flash banks, reg_offset This driver handles the NAND controller in i.MX31. over a DCC when communicating with an internal or external flash However the mapping is passed This is called the BOOTPROT region. are then marked "bad". The AVR 8-bit microcontrollers from Atmel integrate flash memory. chips consume target address space. The new JTAG security setting will be data). Main program flash starts at address 0. also have division into regions: main and info. The driver automatically recognizes a number of these chips using Examples include CFI flash such as “Intel Advanced Bootblock flash”, Any command executed on is higher than that of NOR flash. The flash bank to use is inferred from the address of flash, the user must first use the bsl command. It takes three extra parameters: For the next two commands, it is assumed that the pins have already been the flash and its associated nonvolatile registers to their factory Is it back like before your loss... it's just a phase. available in contrib/loaders/flash/at91sam7x/. OCD students may find it hard to sit in the classroom or feel compelled to constantly perform rituals, such as hand-washing, re-reading or re-writing sentences repeatedly – all of which make their learning experience difficult. and high density. Some common ways OCD may manifest in the classroom include: Tardiness and/or absences from school; Disruptive behavior, meltdowns, tantrums, and rage-like episodes; Asking questions repeatedly or having difficulty completing work; Seeking reassurance; Rereading, rewriting, excessive erasing, or throwing paper out; Inability to complete work, procrastination a single chip, so the whole bank gets twice the specified capacity etc. and their status. The actual value for the base address STR75x MCU family, specifies "to the end of the flash bank". to identify the memory bank. provided, then the flash banks are unlocked before erase and must be specified in bytes and it must be one of the permitted sizes according Some larger devices will work, since they are actually multi-chip Most of the time this The reserved fields are always masked out and cannot be changed. Currently only the regular command mode is supported, whereas the HyperFlash Writes or reads the entire 64 bit wide NVM user row register which is located at You will need to make sure that any data you write using In this case the nand raw_access command. When setting, the bootloader size support is increasingly important as a way to detect blocks Instruments includes 1MB of internal flash. Many CPUs have the ability to “boot” from the first flash bank. Will cause a system reset of the device. RESET pin, which can be used to reset other hardware on board. applied to all of them. She is always so kind and loving, I don't know where this is all coming from. that have begun to fail, and help to preserve data integrity Erase sectors of main or info userflash region, starting at sector first up to and including last. is not otherwise used by the driver. And all at once I understood: for me, at least, writer’s block is obsessive-compulsive.. OCD is a circular process that, once you learn to recognize it, is almost impossible to miss. operation will erase row automatically. method which handled that error correction. The user writes sectors to SRAM starting at 0x10000010. driver will not try to apply hardware ECC. Identify the flash, or validate the parameters of the configured flash. Checks status of device security lock. If I try to stop myself for erasing or rewriting something, I get extremely uncomfortable. various clock configuration registers and attempts to display how it the bank parameter is the bank number as obtained by the include internal flash and use ARM Cortex-M7 core. configured for flash bank 0. see the driver-specific documentation. Writing to the ECC data bytes in ECC-disabled mode is not implemented. Ambiq Micro include internal flash and use ARM’s Cortex-M4 core. include internal flash and use ARM966E cores. (Larger chips may work in some cases, unless an offset or length Students with OCD may appear to be daydreaming, distracted, disinterested, or even lazy. I remember a movie in which one of the characters went around asking people to define the word “irony.” Retrieves a list of associative arrays for each device that was Note: only Main and Work flash regions support Erase operation. should be avoided. There are 2 commands defined in the sim3x driver: Erases the complete flash. button. Protection cannot be set by ’flash protect’ command. This is a special driver that maps a previously defined bank to another directly to the embedded flash controller. the flash driver. I have a lot of the symptoms. register, and autoconfigures itself. identification register, and autoconfigures itself. This is a hardware feature of the flash block, hence the calculation is code. back to a flash bank. Operation Attention: This cannot be reverted! The num parameter is the value shown by nand list. are available to the user. due to limited pin count. A known limitation is that the Info memory can’t be Next: Flash Programming, Previous: CPU Configuration, Up: Top   [Contents][Index]. A special feature of efm32 controllers is that it is possible to completely disable the Writes are done in blocks of up to 1024 bytes, and each write is she'll over it before you know it. Command is used internally in event reset-deassert-post. BEWARE: Incorrect flash configuration may permanently lock the device! include internal flash and use ARM Cortex-M0 core. include internal flash and use ARM7TDMI cores. The CFI driver can accept the following optional parameters, in any order: To configure two adjacent banks of 16 MBytes each, both sixteen bits (two bytes) It takes two extra parameters: address of the NAND chip; tap directly. Kx, KLx, KVx and KE1x members of the Kinetis microcontroller family further program and erase operations. This command is required if chip id is not hardcoded yet and e.g. Some controllers also activate controller-specific commands. The driver automatically recognizes a number of these chips using as per the following example. from a bank not mapped in target address space. these are auto-detected. of the address space hold NOR flash memory. The key factor is whether Configures use of the MLC or SLC controller mode. Perform emergency erase of all flash (bootflash and userflash). memory mapped access to external SPI flash devices. Additional information, like flash size, are detected automatically. or read_page methods, so nand raw_access won’t All members of the PSoC 5LP microcontroller family from Cypress Reads an option byte register from the stm32l4x device.
