Hi,
We make our own DLP4500 control board, but right now the flash is empty. My computer can not find the USB hardware so that I can't upload the configure file to flash using TI's 4500 GUI. I've tried to connect the "HOLD in BOOT" pin to ground, but the result is the same.
I also confirmed the original TI's 4500 lighting board, and put a jumper on "J18". The result is the same with my own board, and can not connect it with my computer via USB cable.
So, how to setup the configure file or says "boot loader" to a brand new control board with a empty flash?
Thank You!
