Arria 10 Passive Serial Configuration Error

We have two PCB designs with Arria 10 FPGAs on then and in both designs we are able to program the devices using the byte blaster 2 cable over JTAG, but on both boards programming over passive serial...

Hi,

It turns out the hardware designer had connected to the AS_DATA0 pin and not the Altera_DATA0 pin. In order to use the 20 prototypes with this mistake, the only option is to implement programming over JTAG from our onboard microcontroller. Since this mechanism doesn't appear to be documented, I'm going to try and reverse engineer the algorithm from the JAM file.

if you have any documentation on this method it would be very helpful ? I can't use the JAM player source code as is since it requires way more memory than our microcontroller has.

Thanks,

Andy
