Unable to halt Hart 992

[RenatoBelmonte]

After I added a module to pulp_soc and synthesized PULPissimo for zcu102 I'm struggling with openocd, this is the result of the debug view. I've installed the patched version of openocd through pulp-sdk and I'm using the last version of PULPissimo

Please, attach a verbose OpenOCD log.
It can be obtained by adding -d3 in the command line or by specifying debug_level 3 in your config file (or via Telnet).
The log can be redirected to a file via -l or log_output respectively.

I've installed the patched version of openocd

Can you please provide the link to this patched OpenOCD version's sources?

I think that the only change is the maximum number of harts

Maybe you could attempt using RISCV OpenOCD?
04d8cfc adds support for up to 2048 harts (the same as the patch from the fork).

The version you are using is out of date. There are quite a few commits in RISC-V OpenOCD that could help with your issue (e.g. 418fcf1 makes DM examination compliant with RISC-V Debug Spec v1.0).

Thank you for your reply. I'll try and let you know
