This is part of my bigger issue where one of my custom board having STM32F4 properly does SPI communication with nano using Jetpack 4.3, but doesn’t work with Jetpack 4.4 or 4.5.
Same SPI test and board on 2 different Jetpack!.
The issue is repeatable always!
I wanted to try some debugging steps by trying to manually control CS.
Thanks Shane. I wanted this for SPI1 too. So I downloaded pin-mux excel sheet from downloads centre to figure out those pins: CS0=TEGRA_GPIO(B, 7) and CS1=TEGRA_GPIO(DD, 0).
Is there a way to add this as DT overlay without changing the current DTB ?
Will be helpful for deployment in the future ?
