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 :)
