Hi Nancy,

The log doesn't have the USB keyboard enumeration log which I asked.

Anyway, if attach this USB keyboard to a Linux PC, does the gets() application work on the PC?

Hi，

USB keyboard is working on the LinuxPc or windowsPC.

On this board ,first define SCANNER_DEV "/dev/input/event3"

fd = open(SCANNER_DEV, O_RDWR);

read(fd,&buff,sizeof(struct input_event))

In the /etc/udev/rules.d ,

SUBSYSTEM=="usb", KERNEL=="1-1", ATTR{idVendor}=="26f1",ATTR{idProduct}=="8801", SYMLINK+="input/event3"

but i can't get a correct info from the HIDkeyboard.

Hi

 Use a standard keyboard (levono keyboard),connect to my board, Still no input data

Kernel v3.2 is very old and no longer supported. Please ask the customer to test the latest Processor SDK v6.3.

Is it 64-bit for ti-processor-sdk-linux-am335x-evm-06.03.00.106-linux-x86 install.bin?I can't open it in Ubuntu12

I believe it is 32-bit. You need to install 32-bit libs on Ubuntu.

What is Ubuntu12? It sounds very old, the current popular versions of Ubuntu is 18.04 or 20.04.
