Cynthion: Feature request for SoC to provide generic JTAG debugging via PMOD #69

Closed nekrondev closed 4 months ago

nekrondev commented 5 months ago

Once Cynthion will be released to the public I guess many folks like to tinker with Facedancer CLI and Moondancer firmware. However the current Moondancer firmware uses the PMOD connectors together with Ladybug library to give some insights using a logic analyzer for debugging USB communications.

As found here there is a FPGA generic way to add JTAG TAP into softcores for debugging the Moondancer firmware directly on the core.

Are there any plans to add this option to Cynthion's SoC?
