I have added a KingTech LCD using RGB 24 bit parallel interface to the TMX320DM365 board using the J18, 19 and 23.
To enable backlight I need to activate the following enablers:
ENABLE_LCD_3V3
LCD_OE_5V
I have used the /usr/bin/mem_util with parameters
0x0b000000 b 0xC0 but when measuring on pin 2 and 10 on J18 are not showing 3.3 V and 5V respectively. There is however a constant 5V on pin 1.
I can toggle the LEDs using 0x04000010 b 0xFF and 0x00 so what is wrong with the parameters for 3V3 and 5V?
