hello,
on our custom AM335x board with a 3.5" QVGA, we are facing a typical issue
the following link about lcd controller mentions screen blanking time default of 10 minutes
http://processors.wiki.ti.com/index.php/AM335x_LCD_Controller_Driver's_Guide
but in our custom board we are getting random blanking time. we are using SDK 5.07 but we changed file system to timesys filesystem.
