Debug: Which version of OpenOCD #999

Closed CLappin closed 3 months ago

CLappin commented 3 months ago

Hi all,

Which version of openocd should be used with the pulp debugger.

I've tried the latest version which doesn't connect correctly, I've also tried the 0.10.0 version that I had which seemed to all connection via telnet.

Any help would be great , Thanks, Ciaran

Hi @CLappin. The CV32E40P does not, but itself, support a debugger. Unless you want to build something from scratch, you will need something like the CORE-V-MCU or X-HEEP.

There is no debug unit neither in cv32e40p system nor in core-v-verif test-bench.

Better to ask in https://github.com/pulp-platform/riscv-dbg/issues or to the 2 projects mentioned by Mike.
