Hi Eason,

Can you show the output logs after executing the following command:

• Power on the TI J784S4 EVM board with default settings below of SW11 , SW7 and SW2
• 

• Enter the following command on the host machine.
  • sudo dfu-util -l

I suspect that the DFU sw settings are incorrect, because my Kaifan and my colleague's development board, using this SW setting, cannot recognize the DFU device

Now I have three TDA4VH_evm boards, using this pin setting, only one board can recognize the DFU device, the other two cannot recognize the DFU device

Hi eason,

You are using TI EVM itself right?
