I am using Ep8260 board having a single Flash Memory Chip (S29GL064M90TAIR32), I need the Flash driver for this flash memory. Can any body tell me that from where I could get the driver for S29GL064M90TAIR32. Can I use the drivers/cfi_flash.c
Is it related to u-boot OR Linux Kernel ??
For U-Boot, in board/ep8260/flash.c, in the Device id finding section, you have to add a few codes to identify your flash and set corresponding info. Like this...
if (flashtest_h == AMD_ID_LV642D) { info->flash_id += FLASH_AM640T; info->sector_count = 127; ( ? Check flash doc) info->size = 0x01000000; ( ? Calculate) }
You have to modify functions(flash_print_info,flash_erase?,..)
I hope, this chip also use the cfi_cmdset_0002. Bcoz I am using S29GL064M90TAIR3 and working with Linux + cfi_cmdset_0002.
HTH :)
