Pulpissimo L2 memory access via JTAG

I was finally able to run hello test in questasim and the memory read/write operations were succesfull there ( also checked  waveforms what happened in the memeory interface)  However , my original problem is not yet solved. I have Pulpissimo in FPGA ( Genesys board actually). I am able to access a few register via jtag, but still not yet L2 memory. I looked the hello test testbenhc in detail and it looks that perhaps some configurations to pulpissimo should be done before being able to access memory via jtag.  there is at least jtag_conf_reg ( address 0x1A104074) which is set to value 0x000030 in tb_pulp.sv.  I tried that but it did not help. Is that correct value and is there some settings to be done? 

regards, skor


Were you able to solve this issue ? I am trying to do the same here.
