@vbuitvydas: Uploading firmware over JTAG was not well tested/reliable in the past and we made some work on this recently. If you are not using upstream version of LiteX, it could be worth testing with it. If still not yet working, I'll have a look.

thanks @enjoy-digital for your reply,
I was using Litex 7062e3379fdd80ac0523390ca46c87906b8c68ff, and updated it to the latest 91fbc79ac2e0af4e9edf3a3fe423f98fb7bdeffb.

Could you retry with:
./limesdr_mini_v2.py --integrated-main-ram-size 0x8000 --load --build --uart-name=jtag_uart
litex_bare_metal_demo --build-path build/limesdr_mini_v2
litex_term jtag --jtag-config=openocd_limesdr_mini_v2.cfg --kernel demo.bin
Seems to have a problem to load a firmware with jtagbone
+ crossover
, but it's working when using jtag_uart

Tried with following commands and it is working now. Thanks!

Hi @trabucayre,
with latest litex updates firmware loading using jtag_uart is no longer working. I followed same steps as mentioned above litex_term gets stuck:
from litex-boards.
Indeed.
It's a regression with commit 6885770e4736b234e65f57840ff8f74a1165a7e0.
After reverting this commit jtag_uart is working.
