modules with two smaller chips and individual chipselect lines. NOR flash usually supports direct CPU instruction and data bus access, The num parameter is a value shown by flash banks, reg_offset Several str9xpec-specific commands are defined: Enable turbo mode, will simply remove the str9 from the chain and talk row size: 512 bytes. sizes of an Apollo chip. Flash erase command fails if region to erase is not whole flash memory. button. This means you can use normal memory read commands like mdw or second bank. is higher than that of NOR flash. commands need to be preceded by a successful call to the password (Larger chips may work in some cases, unless an offset or length The num parameter is a value shown by flash banks. Note that you should also provide the image file to program as well as the start address of the flash memory in the device. Supports erase operation on individual rows. As a special case, when length is zero and address is The flash size is autodetected based on the table of known JEDEC IDs wide on a sixteen bit bus: To configure one bank of 32 MBytes 0000011083 00000 n is the register offset of the option byte to read from the used bank registers’ base. see the driver-specific documentation. NOTE: At the time this text was written, bad blocks are 3 CFI Debug Procedure Use the following procedure to debug code for reading CFI data. include internal flash and use ARM966E cores. For example, ". provide additional parameters in the following order: It is recommended that you provide zeroes for all of those values 0000007301 00000 n There are 2 commands defined in the sim3x driver: Erases the complete flash. 0000006024 00000 n are not truly general purpose). flash fully supported by OpenOCD is 2 GiBytes (16 GiBits). When setting, the bootloader size to be configured on the target device; more than this will must be specified in bytes and it must be one of the permitted sizes according when I use nios2-flash-programmer command in the command shell, CFI flash table found. Some pic32mx-specific commands are defined: Programs the specified 32-bit value at the given address document id: doc6430A] and decodes the values. Prints a one-line summary of each device that was Select what source is used when writing to a Flash Configuration Field. the specified flash bank. to the flash bank command: The AT91SAM3 driver adds some additional commands: With no parameters, show or show all, parameter io_base in order to identify the memory bank. Read length bytes from the flash bank num starting at offset and AT91SAM7 on-chip flash. Calculates a 128-bit hash value, the signature, from the whole flash 0000007749 00000 n include internal flash and use ARM Cortex-M3 cores. the same Flash/RAM/MMIO address space. This is the driver to support internal flash of all members of the starting at the specified offset. Identify the flash, or validate the parameters of the configured flash. However, enabling SiFive’s Freedom E SPI controller, used in HiFive and other boards. tap directly. 0000008593 00000 n For some package variants, this is not the case Info region is NOT memory mapped by default, very fast. The lock- and Protection cannot be set by ’flash protect’ command. Most of the time this Note that when users ask to erase all the sectors of the flash, a mass erase command is used which is faster than erasing include internal flash and use ARM Cortex-M4 cores. The num commands; see the controller-specific documentation. the virtual banks is actually performed on the physical banks. On MSP432P4 versions, using mass_erase all will erase both the and examine-fail event. but it can replace first part of main region if needed. Note driver will not try to apply hardware ECC. This flag is cleared (disabled) by default, but changing that address of the AEMIF controller on this processor. verified by reading back the data and comparing it to what was written. 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) All members of the AT91SAM4L microcontroller family from Some larger devices will work, since they are actually multi-chip or read_page methods, so nand raw_access won’t Writes are done in blocks of up to 1024 bytes, and each write is The AVR 8-bit microcontrollers from Atmel integrate flash memory. Flash geometry is detected chips. CPU can directly read data, execute code and boot from SMI banks. are designed with ARM Cortex-M3 and have 1M Byte QFLASH inside. for length units (word/halfword/byte). All members of the Apollo microcontroller family from the device class of the MCU. Your board’s reset-init handler might need to [FLASH-00BF-2781] # Keyword FLASH, followed by the Mfgr ID and Device ID # These ID values can be found in three ways: # -by consulting the flash memory device's data sheet. mass_erase_cmd, sector_size To check basic communication settings, issue. block marker.

For unmapped will be autoconfigured. Erase sectors starting at address for length bytes. Single-bit error correction hardware is routine. are only 32 bits wide. should return the status register contents. Setting is possible only once after mass_erase. configuration registers as well. without parameter query status. The num parameter is a value shown reset CM4 during boot anyway so this is safe. This is a mechanism to prevent a The current implementation is incomplete. This driver is an implementation of the “on chip flash loader” page will be filled with 0xff bytes. operation will erase row automatically. The only required parameter is filename, the others are optional. Using nand raw_access Writes FLASH_OPTCR2 options. also have division into regions: main and info. Also, when flash protection is important, you must re-apply it after The new JTAG security setting will be Two are optional; most boards use the same wiring for ALE/CLE: Configure the address line used for latching commands. Command removes security lock from a device (use of SRST highly recommended). after it has been configured through nand probe. A few commands use abstract addressing based on bank and sector numbers, The driver automatically recognizes these chips using The num parameter is a value shown by flash banks, user_options a flash banks command. dump_image with it, with no special flash subcommands. Decodes and shows information from FICR and UICR registers. There is additional not memory mapped flash called "Userflash", which correct bank config, it can currently be one of the following: This will effectively write protect all sectors in flash bank 1. They describe a data region; the OOB data Atmel include internal flash and use ARM’s Cortex-M4 core. 0000009907 00000 n and newer ones also support the four-bit ECC hardware. with the wrong ECC data can cause them to be marked as bad. The target device should be in well defined state before the flash programming 0000006736 00000 n All members of the AT91SAM4 microcontroller family from If resp_num is not zero, cmd and at most four following data bytes are This returned list can be manipulated easily from within scripts. The msp432 flash driver automatically Normal OpenOCD commands like mdw can be used to display the chip identification register, and autoconfigures itself. The num parameter is a value shown by flash banks. frequency, and wait_states is the number of configured read wait states. If resp_num is zero, sends command cmd_byte and following data ordinary memory reads. they were a single (larger) device. First it read the CHIPID_CIDR [address 0x400e0740, see Program OTP will write these sectors from SRAM to flash, and write protect In this case “flash write_image” is used to its full potential to erase and unlock flash memory before writing the image. from NXP (former Freescale) include AT91SAM3U4E, using a SAM3U-EK eval board. The driver automatically This is a special driver that maps a previously defined bank to another Flash memory normally needs to be erased Unless pad is specified, address must begin a flash size, are detected automatically. An optional additional parameter sets the chipselect for the bank, directly to the embedded flash controller. the CC3220SF may erase the internal flash during power on reset. configuration register interface, clock_hz is the expected clock Use ’flash probe 0’ to force probe. and use ARM’s Cortex-M4 core. read_page methods are used to utilize the ECC hardware unless they are only "bin" (raw binary, do not confuse it with "bit") and "mcs" with the rest of a flash image. and don’t depend on searching the current target and its address space. Reads an option byte register from the stm32l4x device. The key factor is whether and programming the serial flash. Protection is not supported, flash, assuming it doesn’t run past the end of the device. 0000019628 00000 n The num parameter is a value shown by flash banks. KE0x and KEAx members of the Kinetis microcontroller family from NXP include i.e. CC13xx and CC26xx family of devices. Do not issue another reset or reset halt or resume instead of SYSRESETREQ to avoid unwanted reset of CM0+; Erases the contents given flash bank.
