I am using the ILI9341 driver with an 240x320 LCD and GUIX. It's all working, however, on occasion the system does not want to startup correctly and starts up with a Blank Screen. The backlight does turn on but no images are displayed. If I leave the unit on for a few moments and cycle power, the system starts up correctly. We have checked the hardware and don't believe it's hardware related.
I am using the g_respi_lcdc SPI Driver on r_sci_spi.
I have reduced the bit rate from 100,000 to 32,768 and have added a delays in the initialization sequence with no success.
Any assistance is greatly appreciated.
