Error connect openocd to debug pulpissimo #399

i am implementing Pulissimo project SoC on FPGA. I use Zedboard. I got an error when trying to use openocd to conig jtag for debugging. Please follow the instructions in the readme https://github.com/pulp-platform/pulpiss...nd-openocd I git clone and execute the post-build commands $ git clone https://github.com/pulp-platform/riscv-openocd $ ./bootstrap $ ./config --enable-ftdi $ ./make $ ./make install

I then use the command to connect core riscv to the server $ openocd -f openocd -zedboard-ftdi2232.cfg I received the following error code: $openocd -f openocd-zedboard-ftdi2232.cfg Open On-Chip Debugger 0.10.0+dev-00830-ga88cc98a0 (2023-10-24-16:32) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : Listening on port 6666 for tcl connections Info : Listening on port 4444 for telnet connections Info : clock speed 1000 kHz Warn : There are no enabled taps. AUTO PROBING MIGHT NOT WORK!! Error: JTAG scan chain interrogation failed: all ones Error: Check JTAG interface, timings, target power, etc. Error: Trying to use configured scan chain anyway... Warn : Bypassing JTAG setup events due to errors Warn : gdb services need one or more targets defined

Then I switched to another FPGA. specifically the kintex kc705. I received the following error again: $ openocd -f openocd-kc705.cfg Open On-Chip Debugger 0.10.0+dev-00830-ga88cc98a0 (2023-10-24-16:32) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html openocd-kc705.cfg:21: Error: invalid command name "ftdi" in procedure 'script' at file "embedded:startup.tcl", line 26 at file "openocd-kc705.cfg", line 21

How to configure openocd debugging pulpissimo when developed on FPGA. And I want to develop Pulissimo down to Kintex 7 KC705 FPGA. Can I do it? I'm having trouble
