J101 carrier board with Jetracer Pro AI


I’m trying to use j101v2 carrier board with jetson nano 4GB (taken out from reComputer) with Jetracer Pro AI racing car kit from Waveshare (JetRacer Pro AI Kit - Waveshare Wiki). I followed instructions to boot j101 from SD card, flashed the image from Waveshare (“Install Image” section on their wiki). According to description it’s custom image based on jetpack 4.5.

  1. Board boots up, but Wifi is not working - the wifi module can’t be found. It can be found just fine with the original SW flashed in eMMC. Any ideas how can I proceed here?
  2. How can I power the j101 from GPIO 5v pins? Official nvidia boards have power selector jumpers.
