Hi,
Found the debug setting.
When I try to erase flash under qemu I get the following error, the
erase actually succeeds in the backed file, I see sector as 0xff.
Can anyone check if problem is within u-boot or qemu?
Thanks!
I've found the problem. Paul sent a fix [1] for pflash in June 2013
to make 32 Bit access working with YAMON bootloader.
The fix mirrors the flash status value in the upper 16 Bits of the return
value. Thus U-Boot gets a value of 0x800080 in flash_full_status_check()
after a block erase command. U-Boot compares the status value in
flash_isequal() with the expected value of 0x80 but that fails.
Because of this I think pflash support for Malta is broken since Qemu 1.6.0.
A possible fix could be this:
Hi,
Thanks again.
How do we merge this fix?
Daniel, could you please send a proper patch (non-inlined) for this so
that I can push it to upstream? Or did I miss this patch?
Thanks,
Stefan
