Hi Sreedhar,
Are there some unknwon issues that I should take care of while using this driver for M29W128GH?
M29W128GH is following AMD cmdset. Do I need to add the structure for M29W128GH in jedec_flash.c or there is some chip compatible to this chip is already present in Uboot and I only have to use as it is.
Regards, Prakash

Hi Prakash,
There is a CFI flash driver as you have found it in drivers/. The command set will be same for all the CFI complaint flash chips.
So the cfi_driver.c file will work for you.

Hi All,
I am using a flash memory chip M29W128GH. As per datasheet this memory chip is CFI compliant and so I should use
the
common CFI flash driver for this chip.
But I have seen some review comments on internet saying that UBoot have some error while resetting the M29W128GH flash chip. But in Uboot source code I am not seeing any instances of M29W128GH.
Does UBoot support the flash driver for Flash memory chip M29W128GH? If yes then which flash driver I should use? Will it be from /common folder or specific board folder?
Thanks & regards, Prakash Bedge
