Hello,
I'm trying to use flashrom to write a new bios to my device. It successfully writes the beginning of the bios and then fails with the error:
0x040000-0x040fff:W writing sector at 0xb7ea0000 failed!
And again with the second erase function :
Trying erase function 1... 0x000000-0x00ffff:EW, 0x010000-0x01ffff:S, 0x020000-0x02ffff:S, 0x030000-0x03ffff:S, 0x040000-0x04ffff:W writing sector at 0xb7ea0000 failed!
leaving the bios in an unstable state.
Further experimentation shows that writing the bios fails on both erasing and writing any sector after 0x040000, which is exactly halfway through the bios (2Mb out of 4Mb). Reading from those areas works without a problem.
The lock status for every block is reported as 00, full access.
Full log is below.
I took a look at the source code for flashrom in order to see if I could easily fix the problem. I created a minimal flashrom-like clone that works with my chip:
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <sys/mman.h>
#define D(bios, pos) *((volatile char*)bios + pos)
void write_byte(void* bios, int pos, char value) {
char tmp1, tmp2;
int i = 0;
int tries = 4;
retry:
D(bios, 0x5555) = 0xAA;
D(bios, 0x2AAA) = 0x55;
D(bios, 0x5555) = 0xA0;
D(bios, pos) = value;
tmp1 = D(bios, 0) & 0x40;
while (i++ < 0xFFFFFFF) {
tmp2 = D(bios, 0) & 0x40;
if (tmp1 == tmp2) {
break;
}
tmp1 = tmp2;
}
if (D(bios, pos) != value) {
if (tries > 0) {
tries--;
goto retry;
}
printf("Error writing value\n");
}
}
void try_replace(void* bios, int pos) {
printf("Pos = %x:\n", pos);
printf("Old: %hhx\n", D(bios, pos));
write_byte(bios, pos, 0);
printf("New: %hhx\n", D(bios, pos));
printf("\n");
}
int main() {
int fd = open("/dev/mem", O_RDWR);
void *bios = mmap(NULL, 0x80000, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0xfff80000);
char old;
try_replace(bios, 0);
try_replace(bios, 0x20000);
try_replace(bios, 0x3ff00);
try_replace(bios, 0x40000);
try_replace(bios, 0x50000);
try_replace(bios, 0x60000);
try_replace(bios, 0x70000);
munmap(bios, 0x80000);
close(fd);
return 0;
}
And it outputs:
Pos = 0:
Old: 25
New: 0
Pos = 20000:
Old: 81
New: 0
Pos = 3ff00:
Old: ff
New: 0
Pos = 40000:
Old: ff
Error writing value
New: ff
Pos = 50000:
Old: ff
Error writing value
New: ff
Pos = 60000:
Old: ff
Error writing value
New: ff
Pos = 70000:
Old: ff
Error writing value
New: ff
*Note that running this script will write garbage to your bios. Make sure to keep an original backup nearby.*
As you can see, the problem is easily reproducible. What can cause writing to fail on where the high bit of the address is set (0x40000-0x7ffff)?

Uh oh. Erase/write failed. Checking if anything changed.
Your flash chip is in an unknown state.
Get help on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org with the subject "FAILED: <your board name>"!
