Hi there,
The red LED on the EspressoBin v5 stopped working at Version 20.11.
I opgrade from Armbian_20.02.0-rc1_Espressobin_buster_current_4.19.98
to the laetest version Armbian_20.11_Espressobin_buster_current_5.8.18.
Also not working with Armbian_21.02.0-trunk.18_Espressobin_buster_current_5.8.18.
On Armbian_20.02.0-rc1 to Armbian_20.05.2:
