I have seen that there is a recipe for a mainline kernel version 4.14 compatible with a machine apalis-t30-mainline. I have fumbled around in build/conf/local.conf, meta-toradex-tegra/conf/machine/apalis-t30.conf and then used
bitbake -c devshell virtual/kernel
to get a compiled uImage. I only got to the point where “starting kernel” is the last message over serial console and a black screnn over HDMI. I think that somehing has gone wrong somewhere. I also load over TFTP which adds some complexity sometimes.
What would be a normal procedure to replace the kernel compatible with apalis-t30-mainline instead of the apalis-t30? Are there any changes in u-boot necessary?
