I have just made a board for my own development reference.
The CPU is I.MX6 Ultralite. A TFT LCD is also connected to the LCD interface.
After sending out the gerber file to the PCB manufacturer, I found a mistake about the LCD interface.
I have wrongly connected the LCD's R[7:0], G[7:0], B[7:0] to the CPU's R[0:7], G[0:7], B[0:7].
I know that some CPU sends configuration via the RGB data bus, some others only sends RGB color data via the RGB bus.
I have little knowledge about the I.MX6 Ultralite CPU LCD interface. Would it send only color data via this BUS? If so, then my board would still be used a development board with wrong color displayed on it. Otherwise, the LCD will not display anything meaningful.
Anyone could give me a hint?
