Boot console in a straight Debian install (UbiLinux UpBoard) #449

Closed skorpioskorpio closed 6 years ago

skorpioskorpio commented 7 years ago

All of the examples given seem to use some various /boot/.txt files specific to RPi or BeagleBone (...or...) distributions. I am curious what it takes to implement a boot console in a straight out Debian Jessy like distribution like UbiLinux for the Atom based UpBoard that does not have these files in it's distribution. These pages have been a great help in getting an AdaFruit 3.5TFT working (from X startup on) on these boards, however there is still several issues, this being one of them.

I don't know the UpBoard, but fbcon= controls which fbdev framebuffer fbcon connects to: https://github.com/notro/fbtft/wiki/Boot-console#enable-console

I don't understand which files you are talking about, since the kernel modules has to present for you to get the display working.

If the drivers are modules, the earliest you can load them is in initrd. If you want it to load before that, the driver has to be built into the kernel proper (zImage).

Closing issue since there has been no activity for more than 2 months. Reopen if needed.
