Hi Again,
After adding debug prints in grub_cbfs_mount function in
grub-core/fs/cbfs.c we found that mounting fails due to following check.
ptr = grub_cpu_to_le32 (ptr);
header_off = (grub_disk_get_size (disk) << GRUB_DISK_SECTOR_BITS)
+ (grub_int32_t) ptr;
if (grub_disk_read (disk, 0, header_off,
sizeof (head), &head))
{
grub_dprintf ("cbfs", "FAIL:: :%s:%d\n",__FILE__,__LINE__);
goto fail;
}
Does this gives any idea what could be the problem when CONFIG_CBFS_SIZE
and CONFIG_ROM_SIZE is same in coreboot configuration?
