These comments were a reply to Robert,!but threads are getting confused a bit for everyone especially for me.
Let me look at this more and see if I can find the pinmux pins I need in i-boot and the kernel. Even if they don’t exist in u-boot, they should in the kernel. Then I can do as Robert indicates, change the pinmux U-Boot file and dts. If I go into any more detail, it’s going to take too much time and I’m already behind on this. Robert understands the concerns and what I need. I simply need to pinmux pins E18 and E19. > On Nov 1, 2017, at 1:09 PM, William Hermans <[email protected]> wrote: > > > >> On Wed, Nov 1, 2017 at 11:01 AM, Tracy Smith <[email protected]> wrote: >> Ok look this custom board is based on the BeagleBone Black.
