Subject: Cfi can't probe the flash(am29lv320db)
Date: Fri, 1 Jul 2005 15:03:31 +0800 [thread overview]
Message-ID: <639438900507010003499e2512@mail.gmail.com> (raw)
If i use "map_rom" to probe the flash, the kernel can run normally.
When i probe it with "cfi_probe", it can be found.

The kernel is broken at cfi_send_gen_cmd(0x98, 0x55, base, map, cfi,
