Some good news testing Labrador 64 as an IoT gateway:
platformio and flashing through a ch341 work!
The ch341 is strangely broken on the raspberry pi 3 and works out of the box without errors on Labrador 32 bit and 64 bit.
Compiling and using platformio also seems much faster on the Labrador than on the Pi 3.
Great, good job!
I hope we can fix Ethernet and WiFi quickly, then the Labrador could be used to teach IoT in Brazil (WiFi accesspoint does work with the right masquerade modules on 32 bit, but Ethernet is also heavily broken on Labrador 32 bits).
