Hi list,
I've got a new problem. When I use the command `flash probe 0' after
telnet to the server. It cannot probe the flash.
My core is arm926ejs and flash used CFI interface, so go into the code
and I found something is not normal.
# my flash config
flash bank cfi 0x10000000 0x00800000 2 2 0
At flash/cfi.c
cfi_probe() {
/* snip */
/* detect manufacturer ID */
unlock2 = 0x2AA;
cfi_command(bank, 0x55, command);
if((retval = write_memory(target, flash_addr(bank, 0, unlock2),
buf->width, 1, command)) != ERROR_OK)
{
return retval;
}
/* snip */
}
I found the flash_address is not correct(my fault?), and address is
0x10000554.
>From cfi flash spec, detect manufacturer ID, the byte addr should be
base + 0x555 I think.
After changed manually, it unlucily... SO, in this function, I adjust
write_memory() to target_write_u8() and it can probe success.
I 've no more idea about that.
What's wrong? Is it a bug?
Regards
