Help! SPRACING F3 motor output not working

[Marky]

my setup is simple, a spracing f3 (I found it in an old quad under the basement), 4 x BLHeli_S, and cleanflight for flashing firmware. All the sensor and receiver work fine, but cleanflight or blhelisuite can only recognize escs as well as control motors that connect to port 1 and port 3, the other port (there are total 8 ports) doesn’t get recognized. I have tested all my escs and motors on other setup and it worked fine so I know that problem must be the fc

What firmware and version is on the SPRF3 board?

What firmware and version is on the SPRF3 board?

I have flashed the cleanflight v2.4.0 for it

can someone help me pls? Im desperate here

So here is the last versions of betaflight and cleanflight that supported F3 processors

Betaflight 4.0.6 was the last release supporting the F3
Cleanflight 2.5.0 was the last release supporting the F3

I would recommend betaflight over cleanflight with the latest firmware possible.

Can you post a picture of the board?

thank you for your help sir.
I've try betaflight 4.0.6 as well as cleanflight 2.5.0, still no luck, the board can only detect 2 escs that connect to output1 and output 3, I guess maybe the board was fried somehow cause I can't find any online forum talk about it, this is the picture of my board

I have several of the boards and know what they look like. Was hoping to see a picture of yours to see if I could pick out anything obvious.

Here is the picture of the board, I get 5v from pdb and use 4 blheli_s for control motor

The bottom view of the board is out of focus. Barring retouching the solder joints for the motor ports, everything looks normal.

I have checked all the gnd pin of all 8 port and they all work well (I use multimeter) so I guess if something wrong about soldering it must be the signal pins
