No screen on Tegra B HDMI

Hi SteveNV,
without proxy I have completed the setup. Unfortunately, even after the flash of the latest driveinstall version the USB of the tegra B does not recognize anything. Also trying to connect with minicom does not receive any answer. Are you advised to start the repair process?

Hello, I’m facing the same issue.
I tried @wenwu.deng solution but it didn’t work for me!!

Does anyone know how to fix it?

Could you please a new topic and share all required info and logs to investigate furthur?
