I am using beaglebone black with ubuntu(3.8.13-kernel). I want to interface 7" TFT-Lcd with baglebone black. I designed a hardware with tranceiver (buffer) IC74AVC16T245 which is connected to GPIO ports of beaglebone black. And 40 pin LCD connector is connected to output of tranceiver IC. OE pin is connected to ground. DIR pin is also connected to ground.
Now, I am facing a problem with hardware. If I connect this hardware with beaglebone black, beaglebone black is not booting only power led is on. When I remove that hardware, beaglebone black board is booting properly. I tested a hardware but I didn’t found any mistake. Can i get some guidance or idea to solve this problem?? Thanking you.
