I am a novice, just started to contact artiq for two weeks, and I have been installing artiq before. Today, I started to experiment with the examples given in the manual, but there was something wrong with the first example, led.py, which I followed exactly in the manual, and the result was stuck when I ran it with artiq_run led.py. Machines are not lit up, then I go to, in accordance with the steps to view the log in https://git.m-labs.hk/sinara-hw/assembly/src/branch/master/src/sw_sup/uart_logs.md, also does not have the result, And the following error, please point out the maze, thank you
