Part number S29GL512P http://www.spansion.com/products/S29GL512P.html I have checked uboot source code(1.1.6) it doesn't support this part. How can i make uboot functional for this part ? Do i need to modify any code in uboot ? if yes where should i make those changes ? I would appreciate your pointers on this -- Thanks & Regards Harsh ^ permalink raw reply [flat|nested] 3+ messages in thread

Use the CFI flash support. We use the following for S29GL128N in our board config file. you might have to tweak the values, but it should 'just work'. /* * Flash Controller settings */ #define CFG_FLASH_CFI 1 #define CFG_FLASH_CFI_DRIVER 1 #define CFG_FLASH_CFI_AMD_RESET #define CFG_FLASH_USE_BUFFER_WRITE 1 #define CFG_ENV_SECT_SIZE 0x00020000 #define CFG_MAX_FLASH_BANKS 1 #define CFG_MAX_FLASH_SECT 256 #define CFG_FLASH_BASE 0x10000000 -- Hardware, n.: The parts of a computer system that can be kicked. ^ permalink raw reply [flat|nested] 3+ messages in thread

There is no need to add individual flash chips to the list. Tolunay ^ permalink raw reply [flat|nested] 3+ messages in thread
