[beagleboard] panel suspend


I have followed the instructions of
and installed Angstrom on my SD-Card.
I have set the bootargs as follows:

OMAP3 beagleboard.org # setenv bootcmd "mmc init; fatload mmc 0
0x80300000 uImag
e; bootm 0x80300000"
OMAP3 beagleboard.org # setenv bootargs "console=ttyS2,115200n8
console=tty0 roo
t=/dev/mmcb1k0p2 rw rootwait"
OMAP3 beagleboard.org # boot

It seems that the kernel is well found, but I have the following log
and then it just freezes:

[ 372.090942] cmel_oled43_panel: panel_enable end
[ 372.097991] regulator_init_complete: incomplete constraints,

Do you know where the problem is?



the link that I followed was



Actually i dont know y that problem occured but i have a basic
question.. y u have set console twice with ttys2 and tty0..?

tty0 is supposedly to see the GUI on DVI monitor…tty2 is to see it on touchscreen.
ttyS2 is to see it on your hyper-terminal.

sorry, you cannot see GUI on hyperterminal…you can only see the command line… :stuck_out_tongue:

I have resolved my problem. It was beacause I had locked the SD-Card and then put it in the beagle board slot. It seems that it needs to write back to the card in the process of booting the kernel.
The error that I was getting occures when the GPIO mux is set. I’ve found out that the SD-Card lock is also considered as one of the GPIO’s of the board. So, by removing the lock the problem will be solved.
