Hi, I was wondering what is the recommended Jtag hardware that could be used to debug a litex risc-v cpu, and/or communicate via jtag-uart ?
<Guest17>
I've tried with an Altera USB-Blaster, FTDI FT4232H MINI Module, HW-USBN-2B, Stm32 Blue Pill (flashed with dirtyjtag)... but haven't been able to get OpenOCD or Litex-term to work.

I'm using a Lattice ECP5 on a Colorlight v8 board.
<Guest17>
The LiteX design instantiates a RiscV CPU and a jtag uart.. and I can program the bitstream using OpenFPGALoader and the DirtyJtag,
<Guest17>
just can't connect to the CPU (OpenOCD v0.10 + dirtyjtag patch) nor see the LiteX banner that I imagine is transmitted via the jtag-uart at power on (via litex_term).
