I have a Jetson TX2, Ubuntu 18.04, and L4T R32.3.1. And I need to use SPI interface. As I know, SPI is disable in default.
I am trying to enable SPI interface, using prompts from website https://elinux.org/Jetson/TX2_SPI . But this article is for another version of L4T, and I make some changes, using prompts: change “…/kernel-4.4/…” to “…/kernel-4.9/…”, change “tegra18_defconfig” to “tegra_defconfig”, change “…spi/spidev.ko…” to “…spi/spidev.c…”.
After “Building Kernel” step and rebooting system, my Ubuntu crashes with errors (and not boot):
[FAILED] Failed to start Load Kerlen Modules
[FAILED] Failed to start nvpmodel service
Please, tell me, how to enable and use SPI on Jetson TX2 and R32.3.1? Where can I find usermanual and description, what to do after I will reinstall Ubuntu?
