Hello
I Have the Duet 3 6HC with a raspberry pi in SBC mode. Everything worked well until i accidently erased the firmware on my duet.For some reason I can't upload a new Firmware. I tried to flash it with the raspberry over ssh. I used Bossa but the responce was "Unkwown device at tty/ACM0". After that i tried to install Bossa on my pc. When I connected the duet to my PC, it's recognised as "Bossa Programming Port(COM5)". I can read the flash with the programm but i can't write anything. The Bossa programm gets stuck whenever i try to write anything. The responce that i get is "Writing Page 0 (0%)". No matter how long i leave the programm running, it won't progress. i even tried diffrent versions of the "Duet3Firmware_MB6HC.bin".
How can upload a Firmware again and acces my printer with the DWC?

PS: sorry I couldn't change the topic to FIrmware installation.

I have erased my duet 3 6HC with a jumper connector. Now I am not able to upload a new firmware. Whenever i plug it into my pc the port won't find the correct driver. I have already reinstallt them but it still won't work. I run my duet with a Raspberry Pi SBC. I tried to upload the new firmware with bossa with ssh but i couldn't download things from repos.

How can i restore the Firmware from my duet 3 6HC?

Edit:
How can i download bossa for the Raspberry Pi?
