The common CFI driver provides this weak default implementation for
void __flash_cmd_reset(flash_info_t *info)
* We do not yet know what kind of commandset to use, so we issue
* the reset command in both Intel and AMD variants, in the hope
* that AMD flash roms ignore the Intel command.
flash_write_cmd(info, 0, 0, AMD_CMD_RESET);
flash_write_cmd(info, 0, 0, FLASH_CMD_RESET);
void flash_cmd_reset(flash_info_t *info)
Some flash chips seems to have trouble with this reset sequence. In this case
the board specific code can override this weak default version with a board
specific function. For example the digsy_mtc board equipped with the M29W128GH
from Numonyx needs this version to function properly:
void flash_cmd_reset(flash_info_t *info)
flash_write_cmd(info, 0, 0, AMD_CMD_RESET);
