Help getting console on UART4
Are there any specific kernel config options to get the console to work on UART4?I feel like I've tried every permutation of build, DT, and loading configuration at this point.I'm working on a custom board with a new 'machine' building on the Distrib...
Resolved! What happens if I have a digital logic clock but my STM32MP1 is in "analog bypass mode"?
I have a custom board I made with the STM32MP1 and I seemed to have royally messed up the clock circuit. I have an ASDMB-24.000MHZ-LC-T clock chip generating a square wave clock but HSE_OUT is being pulled high which puts the STM32MP1 into analog-byp...
