Trying to update kernel

[rlevensa]

I installed Bionic Containers aarch64 (DockerCE & Kubernetes) [microSD / eMMC Boot] [0.7.9] image.  I'm booting from a microSD.  I must be missing something obvious, but I can't boot to a different kernel.


The kernel install looks good.

Code:

sudo apt install linux-image-4.14.0-rockchip-ayufan-136-gee91453

The extlinux.conf has the new kernel information.

After rebooting, it still has the original kernel.

uname -r

Thanks for any help!

I remember this error long time ago. Do you have something inside your SPI?
