I'm very new to the image building process, so please excuse my maybe stupid newbie question.
I have this device using MT7620a + MT7610e EVB, the same as in this thread:
If I flash the initramfs image, it works well. Using the squashfs image, the kernel boot fails with these error messages:
[ 0.766222] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6 [ 0.781014] Please append a correct "root=" boot option; here are the available partitions: [ 0.797592] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) [ 0.814958] Rebooting in 1 seconds..
Reading the linked thread it gets clear that the device uses a different partition table than the default image. Modifying the corresponding dts file seems to solve the problem. I found the file, tinkered a bit with it and built some different images, but none of them worked. I sadly don't know enogh about this topic.
Thank you very much in advance.
