Re: RevPi not responding after re-imaging
Hi jonaswiberg, you can use a tool that writes and reads out the written image to prove that the eMMC is written correct. For example, you can use balena Etcher for this. Then, if the problem persists, you can use an HDMI monitor and a USB keyboard to check for erroneous behavior during boot and try...

Re: does RevPi Connect S support Using RS485 as a Serial Console?
Hi Peter, ttyAMA0 is the PiBridge and therefore cannot work. "ttyRS485" is a symlink that points to the actual UART. As this UART is only set later during booting, the target must be used. Query can be made with readlink /dev/ttyRS485 i.e. pi@RevPi99988:~ $ readlink /dev/ttyRS485 ttyAMA5

Re: Problems flashing RevPi Connect 4
Hey Steffen, many thanks for the detailed description and for posting it anyway - please don't hesitate to do so here, as it helps us and others to understand where the problems lie. The USB issue is complex. I have added it to the RevPi RPiBoot Checklist.

Re: RevPi Start nicht
Hallo Cedric und willkommen in der Revolution Pi Community! Was hat sich denn verändert seit gestern? Falls Dein Gerät nicht bootet, bitte prüfe, ob Du ein Micro-USB-Kabel verbunden hast. Wenn Du die Möglichkeit hast, einen HDMI Bildschirm anzuschließen, kannst Du den Bootvorgang betrachten. Sollten...

Re: WLAN Verbindung
Hi Verhoeven, momentan funktioniert die WLAN-Verbindung nur eingeschränkt. Mit 5.4 GHz sollte es funktionieren.
Edit: probiere diesen Kniff - damit funktioniert auch die 2.4 GHz WLAN-Verbindung bei uns:
