I ported and enabled the eeprom commands to u-boot.
From the readme file, it expects a bin file to be
loaded into ram and then using the "eeprom write" command we should be able to program the eeprom. => tftp 100000 eeprom.bin => md 100000 => eeprom write 100000 0 100 => eeprom read 150000 0 100 => md 150000 However, when I try the above and check the eeprom content only the last few bytes are programmed. Any idea? How to generate this bin file? Also, the "imd" command is not working properly on my set up.
I am using u-boot version 1.1.2 on a custom board with mpc8541 cpu.
Only last few bytes are written in flash after a sequential write block?
Usually indicates that the flash bus has a SMALLER bus width support (i.e., 8 or 16-bit) and software operation is performing 32-bit operations instead.
