Question from an FPGA newbie - can code running in a PicoRV32 on an FPGA like iCE40-HX-4K be debugged via JTAG? @oe1cxw Thanks!
Replying to @electronutLabs
Picorv32 has a trace port, but not via jtag (no jtag on iCE40 either) and not compatible with risc-v debug spec. Also no hardware debug support (besides trap instruction), but it should be fairly easy to write a gdb stub that would allow step debugging of non-irq code.
