Pulpissimo bitstream generation.

Hey,

I am stuck also at that error " openocd: src/target/riscv/riscv.c:2530: riscv_set_current_hartid: Assertion `riscv_hart_enabled(target, hartid)' failed. ", I've read the comments but I couldn't locate that patched openocd that comes with the SDK. May you please elaborate more one this  ?

Thanks !

Hi AhmedZaky,

I just realized that the patched Openocd is not installed by default if you do not have access to the artifactory server (file server at ETH that contains precompiled binaries). However 
I revised the README in the fpga branch and added some sections on how to install the patched OpenOCD from source. Please follow the instructions at https://github.com/pulp-platform/pulpiss...nd-openocd.

Hey Thanks for your reply, I already applied the patch manually to the source file of openocd and it works. 

Noe wen I try to either run the example the FPGA or trying to debug I got the following errors: 

1- When I am trying to run the example directly without debugging using the " make run" command: 


"/pulp-sdk/pkg/sdk/dev/install/ws/python/runner/fpga/pulpissimo/elf_run.gdb:1: Error in sourced command file:  localhost:3333: Connection timed out" 

2- when I try to use the debugger by running three terminals at the same time " openocd, GDB and screen / minicom" I face the following issue: 

            - Minicom: I receive nothing from minicom, and I am assigning the right USB port hopefully. 
            - Screen: I receive odd characters instead of the real message. 

Could you please help on that ? What might be the problem ? 

Thanks so much !
