Thank you very much on your help with OpenOCD. By the way, do you have any idea how to integrate 3rd party module into PULPissimo via AXI interface? I have tried connect it to AXI interface in the top level of pulp_soc (which is used for cluster) and soc_interconnect but both of them don't work.
Thank you in advance.

Hi gideros,
In theory it should work straight out of the box if you connect the currently dangling ports in the toplevel pulpissimo.sv. You find the address of the AXI plug in ips/pulp_soc/rtl/pulp_soc/soc_interconnect.sv on line 260 and 261 (base address: 0x1000_0000, end_address: 0x1040_0000). For reference you should have a look at https://github.com/pulp-platform/pulp. In this project PULPissimo is connected to an 8 core cluster connected on the AXI plug. This should give you an idea on how to connect your 3rd party module. Most of our own accelerators we developed so far were integrated by directly connecting them to the TCDM bus to get direct access to the shared memory.
Greetings,
Manuel
