Other Parts Discussed in Thread: SYSCONFIG
Currently, we have identified a bug related to pinmux.
We configured the PRU's GPIO pins in sysconfig to operate in GPO (General Purpose Output) mode. After configuration, we observed that the GPOs were immediately outputting a high signal.(PRG0_PRU1_GPI19)
We then changed the GPO's NO PULL setting to PULL DOWN in sysconfig and re-ran the system, but the GPOs remained high and could not be pulled low.
However, in our usage requirements, it is necessary to initially set the GPOs to output a low signal.
