CPS2 build not flashing

[marcusrushy]

Might transfer everything to another board and test each component. 🙃

If you suspect the PCB, you can just transfer FPGA, flash, regulators and R16-24 to be able to test JTAG.

I give up. Cannot seem to get this working. Will have to buy one when I get some money.

I’m curious as to whether you would be willing to sell your problem board?  I’d be interested in seeing what I can do with it, and I have a working board to test it against.

[marcusrushy]

I would yeah but don’t have the FPGA chip anymore.

Having another go at this CPS2 build. Need to get another FPGA chip but been testing the diode in the picture with a multi meter. If I put the red lead on the right side and black on left side I get .668. If I put black on the right and red on the left I get .464. I thought I shouldn’t get any reading. Thanks

It looks like the diode is still installed the wrong way.

[marcusrushy]

I checked with a multi meter before installing which way round to put it

[marcusrushy]

Found a picture on Google and yeah it looks like it is on the wrong way 🙂

[marcusrushy]

Is this diode the correct way round. Thanks

[marqs]

Is this diode the correct way round. Thanks

Doesn’t seem to be.

[marcusrushy]

Wow I am bad at diodes

[marcusrushy]

Diodes the correct way round now. Will be ordering an FPGA in the next month or so. Will keep you updated. Thanks
