Error with OpenOCD

[odedeini]

Hi,

I followed the instructions for the implementation of the platform over vcu118 FPGA.

I programmed the FPGA with the bitstream and closed the connected server from Vivado.

I cloned pulp-sdk with the mentioned tag and built it accordingly.

A config file for vcu118 is not provided so I looked online and gathered configurations to a config file (I set the frequency as 10MHz everywhere so I also set it as 10MHz for the config file):

The output of the command "$OPENOCD/bin/openocd -f ./vcu118.cfg" is:

I don't know if it matters, but in Vivado I noticed that the ID code of the xcvu9p_0 chip is also 14B31093 (same as in the previous output).

Thanks for your help
