VT6421 sata card with sst39Vf512 eprom

[Antonio Estrada Respeto]

I have tried the below flashrom option (code tested) in order to find a right response on my no name VT6421A pci sata card, but no luck. Environment is Freedos in an usb boot sdcard device in a standard PC. Address was from 0xffff0000 to others. The card is found by flashrom at 1106:3249  BDF 02:0b.0 . The card has an Eprom flashable sst39Vf512 at is printed in top of it. Final messages are:

Requested bar is of type rom.
Error:  No suported PCI found.
Error: Program initialization failed.

I managed flashrom to work with my 3C905TX and do it in the same environment as a charm. I know VT6421A hardware is very tricky depending on every pci maker. The final goal is to flash a 64k boot rom ins this card. Any help will be wellcome.

Thanks in advance.

The code tested:

flashrom –p atavia offset=(different address) –V

The VT6421A only supports LPC/FWH (or one or the other, I forget which)
protocol only.  I believe the SST39VF512 is a parallel Flash EEPROM-style
interface.

Please post a log file. You can generate it with "-o logfilename.txt".

Thank you for your support.

I have tried to take the output file as you request, but no luck. I always 
start freedos in my usb sdcard boot choosing the number 3 option, then input 
cswdpr0, and then execute flashrom comand. But if I try to make -o 
logfilename.txt, the system refuses to save the file (it says that the file 
does not exists). If I do not execute cswdpr0 at first time, always have a 
disk write error. I suppose it will be related to the file log error.
