Hello, can you point which JTAG you using for this project? There are many old JTAG ports on that site.

Thank you,

Hi,

I use the ft2232HL as the connector. Can it be used to debug? I use it and get some log: Open On-Chip Debugger 0.10.0+dev-00849-gcbb15587d (2020-09-10-11:59) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : clock speed 100 kHz Info : JTAG tap: riscv.cpu tap/device found: 0x00000001 (mfg: 0x000 (), part: 0x0000, ver: 0x0) Error: Debug Module did not become active. dmcontrol=0x0 Info : Listening on port 3333 for gdb connections Error: Target not examined yet

I change the swerv_eh1's branch to 1.4 and solve this problem.
