Can you help me? I'm working on VIA-EPIA

[gimyung han]

hi everyone !!

I'm trying to burn romimage on the VIA-EPIA (VIA C3-800 Mhz, VT8231)

I just succeeded in making romimage, and I cd into 
/freebios/util/flash_and_burn, and type make to compile.

Finally, I got  excutive file "flash_rom".

To test "flash_rom", I typed flash_rom without any parameter.
and I saw following message

Calibrating timer since microsleep sucks ... takes a second
Setting up microsecond timing loop
153M loops per second
OK, calibrated, now do the deed
Enabling flash write on VT8231...tried to set 0x44 to 0x54 on VT8231 failed

Part is SST39SF020A
OK, only ENABLING flash write, but NOT FLASHING

and then, I type "./flash_rom /root/epia/romimage".

"/root/epia/romimage" is a full path of romimage I had made.

I saw messges like below

I thought, romimage was burnt on my rom.........
I reboot the system, buf nothing was changed............

What's wrong with my procedure.....................

I did change original rom..............................

is it impossible to burn image on the original rom ?

If so, What should I do?

Please, give me your wise advice.....

it's annoying, but you have to say:
./flash_rom -w /root/epia/romimage.

That should do it.

I thought this was a bug made by me and sent a patch to Ron some weeks ago,
but it seems it is not committed.

Attached is CVS diff against my current tree.
Beside 2 bug fixes (both by me), this includes some enhancements.
If you can't accept these, I will make a patch consists of only bug
fixes.

* Fixed to do write operation when no option but a filename is supplied
* Fixed wrong error report when enabling flash on vt8231
* Changed to report progress every 4KB instead of byte by byte on some chips
(significantly speeds up flashing those chips)
* Added -c option: only specified Flash ROM is probed; this saves
BIOS Savior users from accidentially overwrite the "known good" BIOS
if he/she forgot to toggle the switch.

It compiles and works fine for me.

Btw, Ron, could you commit my other fix to elfboot.c in the freebios tree?
It's a trivial bug fix, the freebios2 tree seems already 
has that fix applied by Eric.
