Hi guys,
I cost my sunday to enable the SPI on xavier, I find some guide here,
like this topics:
https://devtalk.nvidia.com/default/topic/1044595/jetson-agx-xavier/question-how-do-i-enable-and-address-spi-ports-/
and officail guide for TX2:
Jetson/TX2 SPI - eLinux.org
and when I fellow them to this step:
sudo dd if=tegra194-p2888-0001-p2822-0000-base.dtb of=/dev/mmcblk0p31
I dont know what ‘mmcblk0p31’ mean, may be it will be replace with mmcblk0p1(official for TX2)
when I use mmcblk0p1. after reboot, my xavier cant boot and show:
Kernel panic-not syncing: VFS: unable to mount root fs on unknown-block(179,1)
I find a gude to solve this kind of problem, but it works when ubuntu in recovery mode.I want to use hold on 'shift' to get in ubuntu recovery mode, but I find I cant connect keyboard at all.
I dont know how can I deal with this ,can anyone help me. I have some code in xavier, I know reflash will work,but I dont want to do like this.
thanks a lot
