IMPOSSIBLE TO UPDATE BOOTLOADER TOOLBOARD 1LC
-
I can't update the bootloader of my 1LC toolboard.
My system (SBC mode) consists of a Duet 3 MB6HC version 3.5.0-rc.1 board, a Duet TOOL1LC rev 1.3 firmware version 3.5.0-rc.1 board.
I uploaded the files Duet3_CANiap32_MB6HC.bin, Duet3Bootloader-SAMC21.bin and Duet3Bootloader-SAME5x.bin into the firmware folder.
From the console I execute the command M997 B121 S3, but the bootloader always remains at version 2.4.
What am I doing wrong? -
@Gianluca what release are you trying to install?

@jay_s_uk
I currently have 2.4 and would like to install the latest 2.8 -
- Make quite sure that the version of Duet3Bootloader-SAMC21.bin in /firmware on the SD card is the version that you want to install.
- Use M122 B121 to check the VIN voltage measured by the tool board. The tool board will refuse to update the bootloader if the VN voltage looks low.
- Send the M997 B121 S3 command and watch the red STATUS LED on the tool board. If it flashes, count the number of them. If the firmware can't update the bootloader, the number of flashes will indicate the reason. See https://docs.duet3d.com/en/User_manual/Machine_configuration/CAN_connection#led-behaviour-and-error-codes.

@Gianluca I've just tried to upgrade a tool board with a 2.3 bootloader to 2.8 and it has failed too. I will look into it.

OK, I'm waiting for some news.
I was probably doing everything correct.
However, the bootloader is the latest corrected version (https://github.com/Duet3D/Duet3Bootloader/releases/tag/2.8), the voltage is 30.0V, and the status LED after the M997 B121 S3 seems to me to do 6 quick flashes and then back to one per second.
After M997 the hotend temperature reads 2000°C. -
@Gianluca I have confirmed and fixed this issue in the source code. See https://github.com/Duet3D/RepRapFirmware/issues/903.
If you wish, you may upgrade the tool board to the new firmware at https://www.dropbox.com/scl/fo/tjznycpk7bv7sj71p0ssl/h?rlkey=ac2zcmrirq51kvzrrtsrsfy6n&dl=0 (compatible with 3.5.0-rc.1) and then upgrade the bootloader.
