Hi Srinath,

Currently I am using the u-boot-1.2.0, I am trying to have a single Uboot Image which supports non-CFI flash with different sector size and flash sizes say for e.g. 8 MB flash with 64KB sector size, 16MB flash with 64KB and 16MB flash with 256KB sector size. Form uboot sources it evident multiple flashes (change in flash size and sector size) are supported using config options. It's also documented ENV_SECT_SIZE should be equal to Sector size of flash.

Unfortunately currently you have to provide a board specific NOR FLASH driver to support non-CFI flash's, which many boards do. This will change in the near future since I have a patch in the queue that will add a JEDEC style flash support from Linux to the common CFI flash driver.

BTW: Supporting multiple flash chips with different sector sizes is no problem at all.

Can someone please suggest the possible way to support multiple flashes in a single uboot binary? (Assuming commands are unique across all flashes).

Please wait a little while till the new infrastructure is in place. Then you can add your flash support much easier in the common driver.

Best regards, Stefan
