I rebuilt the image, with the proper layers, but still I get an
incorrect u-boot environment. Full u-boot serial output and boot log
follow below.
uname -a prints: Linux beaglebone 3.14.16 #1 Thu Aug 14 18:00:21 CEST
2014 armv7l GNU/Linux
(the kernel was built by the linux-ti-staging recipe)
The u-boot problem bootfile is set to uImage, and mmcboot uses bootm
instead of bootz.
Furthermore, once I correct these two values, it boots, but I see this
eventually:
Error opening /dev/fb0: No such file or directory
After a bit of investigation, it turned out that omaplfb wasn't loading
due to missing symbols:
root at beaglebone:~# modprobe omaplfb
[ 83.010309] omaplfb: Unknown symbol register_vsync_cb (err 0)
[ 83.016642] omaplfb: Unknown symbol unregister_vsync_cb (err 0)
Searching for this, I found
https://groups.google.com/forum/#!topic/beagleboard/dcLtpK7ZsX0 .
According to this, in the kernel log, I should set CONFIG_FB_DA8XX to
"y". Is this still correct for linux-ti-staging 3.14.16 ?
Layer git configuration:
All layers are in their daisy branches.
