hi: i use the GUN tools. flash_utils.tar.gz now I can read the flash ID,(K9F1208U0C):ID = 0x000000EC0x000000760x000000A50x000000C0 but i cannot write data to page, so i cannot use UBOOT! Therefor i doubt that uboot also has the same problem? i have tried several days, but cannot figure it out yet! help! regards!
