I booted the iMX8 with a Apalis-iMX8_ToradexEasyInstaller_2.0b4-20200519 from sdcard. Because I could not get an Internet connection the only possible option to install was the ToradexEasyInstaller. After I installed the ToradexEasyInstaller. I could not get any output from the board neither from the hdmi port nor through the serial port so I tried to install an Image via Recovery mode but hat also did not work. The ./recovery-linux.sh fails at 24% with the output for Apalis-iMX8_ToradexEasyInstaller_2.0b5-20200519 :
Thank you very much! Now at least the recovery mode worked. However when I install an image and reboot I still do not have any output via serial port or hdmi.
