Hi all,
iMX51 + WinEC700.
The BSP is based on the BSP from Freescale.
Sometimes happens that at the OS start - after the bootloader - the screen stays blank (especially if i'm running with the batteries, with the wall charger i never see that).
If I check on the debug log i see the following:
1. correct

CKIH2_CAMP2 = 0 Hz

The screen is initialized between the USB detections (always..).
When I have the blank screen the log is:
...

That means that the LCD driver (and the next apps) is not loaded but i don't know why???
Any idea?
