@droftarts Dear Ian, I made it. It worked. I used a DuetPi image and I could flash the 6HC. A bit tedious and I hope that the normal flashing works for the next firmware version. Many thanks for your help and guidance. Would not have been able to do it without you. Thanks.

@droftarts Dear Ian, your efforts are highly appreciated. However, I consider now to use my 6HC in SBC mode, since I bought a new raspberry. Then firmware updates hopefully become less of a problem since Bossa worked like a charm on your raspi OS.

@droftarts Hi Ian, yes, quite tedious to get the board back running. Just to confirm. Should I connect the Duet 6HC board via USB to the raspberry pi or should I use the flat ribbon cable, which was included with the duet board?

@Phaedrux Good morning, I organised myself a raspberry pi, but ran into the next problem and need your guidance.
I receive a fatal error installing Bossa on the board. I reinstalled the OS to the raspberry, but I get the same error and cannot continue. No idea what to do now. Here the error:

@Phaedrux Hi, currently no free raspberry pi. I have one older Intel based Mac.

Is there someone from Duet3d who has a solution for my problem, please?

@jay_s_uk I bought it directly from the UK.

@jay_s_uk Singapore

@jay_s_uk OMG. I hope Duet3d is working on a fix for Mac users… Is it possible to ask Duet to reflash my board or exchange it for me?

@jay_s_uk thanks again. It looks very complicated with MacOS and not sure if it works at all. Is there no other solution? I do not want to spend hours to get my printer up and running. I always use the latest stable firmware to avoid trouble… which did not work this time.
