[hpsdr] Hermes Troublshooting Help

[Joe Martin K5SO]

Dave, 

You can load the Hermes.rbf code directly (and easily) by using a blaster cable (or clone) onto P2, running the Quartus II Programmer utility in "Active Programming" mode.  If you have a blaster cable and are not familiar with using it I can help guide you through it step by step, it could turn out to be your preferred method for updating the firmware.

No sign of any connectivity to the network on the switch. I ordered a replacement 2N7002K for Q2 from DigiKey yesterday but I don't think that alone would knock out the TCP/IP connectivity and the status diodes . Looking for troubleshooting kick start. I've been taking voltage measurements on the board from the schematics but got to thinking there may be some firmware I zapped which needs reloading through a method not accessible when the TCP/IP route is blocked. I've done a complete inspection of the top and the bottom of the board and this is the only sign of visible damage.
