I am trying to test linux-on-litex-vexriscv on Genesys2 board. When I load the bitstream with command "$ ./make.py --board=genesys2 --cpu-count=4 --load", the command runs but nothing happened on the Genesys2 board. However, after I launch Vivado and open a project and click Open Hardware Manager => Open Target =>Auto Connect, the "Programming Done LED" lights up and the chasing LEDs animation start to run. It seems that "./make.py --board=genesys2 --cpu-count=4 --load" can finish bitstream programming but does not activate the hardware to start running. Is there anything wrong with the configuration/settings ?
Thanks,

TParng

I found the solution: reduce the "adapter_khz" (in linux-on-litex-vexriscv/prog/openocd_genesys2.cfg) from 25000 down to 4000 ~ 1000. Then it works fine.
