OPENOCD issue with Nexys video

[sreya-12]

Hello, I am new to riscv .I am trying to use openocd for nexys_video fpga.But the openocd is not working.having a error at 6 th line in configuration file which i am unable to rectify

Your screenshot is difficult to read and posting screenshots isn't really a good way to provide info in any case. You would be better off posting a verbose -d OpenOCD log and details of the script(s) that you're using.

Edit: screenshot was removed from the original post since I posted the above.

Following is my nexys_video.cfg file for openocd

I am trying to run a baremetal program on nexys-video FPGA .I am stuck at this point.Is there any need to edit this openocd cfg file.I have tried Xsdb as well for running a elf file on RISCV based rocketchip SoC.But I guess it supports only arm based and micro-blaze designs.

You didn't attach a verbose OpenOCD log generated using -d.

What is your command line for invoking OpenOCD? The following suggests that you're not passing any script(s) from the command line so it falls back to openocd.cfg (in the current directory) and doesn't find it.

embedded:startup.tcl:26: Error: Can't find openocd.cfg in procedure 'script' at file "embedded:startup.tcl", line 26

BTW "openocd issue" really isn't a useful/descriptive title for your issue. The original title was better.

I used the command openocd -f nexys_video.cfg and the output is as follows

Error: invalid subcommand "driver ftdi"

That's a different error to your earlier post and suggests some problem with your script that needs to be fixed according to the OpenOCD documentation.

Thanks i will check on that

@sreya-12, is the issue still relevant? I would like to close it.
