Is there a Linux command to enable the load switches for VCC3V3_RPI and VCC5V0_RPI on the AM64x Starter Kit board?

Hey Bob,

Our subject matter expert is out right now, but I do not think they are exposed in a manner that is easily accessible by default under linux. I'll let Bin comment on this though.

Hi Bob,

If you use SDK 8.x (which kernel has GPIO sysfs enabled), you can follow the instruction below.

https://dev.ti.com/tirex/explore/node?a=7qm9DIS__8.4.1.4%20v1&node=A__AOAoFu65t.CYi8Nu4Cd4ng__linux_academy_am64x__7qm9DIS__8.4.1.4%20v1

If you use SDK9.0 (which kernel has GPIO sysfs disabled), you would have use gpioinfo and gpioset commands.
