Duet 3 6HC - Firmware Upgrade - Flash locked

MartinNYHC

Hi All,

just want to update my brand new Duet 3 6HC. Unfortunately BOSSA still doesn' work on newer Mac OS versions, so I used the command line tool bossac.

./bossac -p /dev/cu.usbmodem143101 -e -w -v -b /Users/martin.ziegler/Downloads/Duet2and3Firmware-3.1.1/Duet3Firmware_MB6HC.bin

Erase flash

Done in 3.619 seconds
Write 570776 bytes to flash (1115 pages)
[===                           ] 10% (118/1115 pages)
Flash page is locked

Even if I use the 'u' flag to unlock the flash it does not work.

Am I doing something wrong?

Thanks, Martin

AFAIR, if you use the Erase jumper then it should unlock the flash.

That's what I did. At least I think so

Placed the junper, powered up the board, removed the jumper and started flashing.

Thanks, Martin

Hm, could you try building one of the pull requests that is meant to potentially address that bug? Although getting stuck on flash locked isn't quite same symptom "everyone" else have reported. (save some hassle by only building the cli versionmake bossac)

Or you could try resorting to using a virtual machine running linux or windows (at least one other user had success with virtualbox + windows) I have used ubuntu and rasbpian with success as well.

Compiled the master branch and it works Thanks!

Compiled the master branch

awesome; it'd be great if you could leave some instructions for other mac users to follow, or upload a binary or something as every now and then this issue pops up and there aren't that many active members that are big on macs here.

MartinNYHC

Sure. What's the best place to upload the file? The forum doens't accept these kind of file type.

a zip file maybe - or any generic sharing service like https://wetransfer.com/ etc

Here we go....
