UART communication broken on upstream LiteX+Zephyr #3

Closed lindemer closed 3 years ago

lindemer commented 3 years ago

I've experienced two separate but possibly related bugs attempting to run Zephyr on LiteX.

  1. Full description here: https://github.com/zephyrproject-rtos/zephyr/issues/30702. After zephyr-v2.1.0 the Zephyr shell module no longer accepts keyboard input.
  2. If I update the LiteX sources in this repository by running ./litex_setup.py init install --user from the third_party/litex directory, the problem gets worse. The Zephyr shell is broken on zephyr-v2.1.0 and even the hello_world sample fails in releases more recent that this.

I haven't had any luck tracking down the source of these bugs, and I'm unable to proceed with development until this is fixed.

Hi @lindemer The issue should be fixed by https://github.com/litex-hub/zephyr-on-litex-vexriscv/commit/e94a239c9396debdbbb875b0d75d615c20308552 (thanks to moving the peripherals around a little bit).
