Basically adding to system dtb file - same as this thread - JP6 - SPI3 (/dev/spidev2.0) is not showing up after setting up overlay
Flashed on the dev kit and running on custom board. Have run this process dozens of times w/o issue. Our other dev system which was prepared the same way is not having this issue. It boots normally.
What exactly is it trying to update every time and what is failing ?
