I have a raspberry pi 2B and I wanted to install alpine linux in sys mode. I use a 64gb microsd samsung evo plus. I followed the wiki of alpine here formatting like in troubleshot the boot partition in fat32. However that doesn't seem to work. Something happened to be different in the responses to the commands, ln -s media/mmcblk0p1/boot boot is expected to give an error but it didn't gave one and the reboot doesn't takes minutes like it is written in the wiki.

When at the end I reboot there are some errors at boot:

  • first the clock Clock skew detected with '(null)'
  • Mounting modloop -> ERROR: modloop failed to start
  • then I have several modprobe: can't change directory to '/lib/modules': no such file or directory on
    • starting busybox mdev
    • loading hardware drivers
    • loading modules

You have a photo below, I don't know where to find these logs to copy them as text

alpine boot

Then, this is the dmesg log:

Since I followed all the instructions, my questions are: is there something more that I have to do in order to make it work? Did anybody get it work on 2B? I think yes since it is cited in the troubleshot section of the wiki, so I am missing definitely something.
