Hi
I have got 2 faulty BeMicro Max 10 FPGA boards for free. Both had a short between 5V and ground. I tracked it down to the FT240X USB-Parallel converter.
After desoldering i measured <0.05? from each supply pin to ground (even the 3.3V output)
So i ordered new ones, changed PID/VID, PC detected it as Altera USB Blaster, tried to program and ... nothing
After a quick look into the schematics i noticed that CBUS5 and CBUS6 are connected to CLK2 and CLK 3 pin of the MAX V and the 24MHz crystal(Y2) is not populated.
I tried different settings for CBUS5/6: 24MHz, 12MHz, 6MHz, high, low,...
With 24MHz on 5 and anything on 6, the LED D11 comes on as soon as i click "auto detect" in the programmer, but nothing happens(timeout).
Is anyone here with a working board? Could you please measure these two signals (or read the setting with the FTDI tool)?
Pins: 40 and 42 on the MAX V or 19 and 20 on the FT240X.
Many thanks
Lukas
