i asked if CPU still runs on "this" motherbard with PCIe GPU ? from that side socflash may be a chance, but i am not sure.
I guess I'm being dumb, but with the BMC dead, I don't know how to startup this motherboard. If there's a way to startup the motherboard, please let me know :). When I apply power it comes up with the FPGA CRC fault LED on, and nothing will cause it to power up further than that....

The SOIC16 clip is here now, but I have a feeling that's wired up wrong.... I can't get flashrom to recognise either the BMC or the BIOS chip.

Presumably the red cable is supposed to connect to the red dot pin on the chip, but the way it's wired that isn't a valid orientation...

ch341a can only flash pin. there are special SOP16 to Dip8 clamps.
you don't need /reset 4-6 and 11-14 are nc

Thanks, although I'm not sure what to do with this information :(

The clamp I currently have (and is pictured above) is This one

Do I need Something like : THIS instead?

i gueess you have broken FPGA(CPLD) too, afaik no way then.

happy to get the right one.

Do the job?

if not, could you be kind enough to provide a link, ideally for a UK supplier? (Amazon is fine :))
DIP8 (8pin) to the programmer, ch341a can only flash 8pin, the other/upper 8 pins are for 24 series chips.
check the picture above.

if you look at the ch341a pinout, pin1 of the socket doesn't match pin1 of the cable.

Hi - has anyone actually figured out which PINS are which on the BMI console header?

I've been through all the combinations, and whilst several result in garbled output, I've not yet managed to get a usable console session.

Background - fairly sure I've bricked the BMI firmware by loading the one that's too big :(

Hoping to restore it over a serial console.

Tried both minicom and two (at 115200 BAUD no flow control stopbits 1, parity none, databits 8)

@adam2eden @MartB

TIA

I didn't figure out how to fix it with the serial port.

I ended up reprogram my BIOS using a clip and a programmer. Unfortunately I didn't write down the steps. I found a few bookmarks I saved from that time though, and a photo showing the setup.

winbond 25q256jvfq 16pin`

I remember the data sheet of the chip also helped me a lot.

I also opened an RMA with Tyan and they were willing to fix it for ~$80 even the warranty expired. That was my back up plan at the time.

Ok thanks.

Starting to make sense now.
So we need to connect to pins 1,2,7,8,9,10,15,16 on the chip to 1-8 on the 25XX “half”, right?
Hmm. So I got the clip from Ali, and suspect I'm still doing something wrong.

Flashrom says:
```
Couldn't open device 1a86:5512.


Error: Programmer initialization failed.```

The PSU is disconnected from the mains, and the CMOS battery is out, but when I connect the clip LEDs light up on the Mobo.

Tried every possible orientation (there are only 4), and no dice. I have the 3.3V jumper set on the CH341a, presumably that's correct?

if you never used this it's hard to say what the issue is now.
remove/disconnect anything.
the light come up, thats expected, because the BIOS chip is supplied by 3.3V
in some rare cases this in circuit programming is impossible.
