Duet3 Expansion Board 3hc blocks during downgrade
-
Hi,
I have bought a new duet3 with a duet3 expansion board 3hc. I installed the latest firmware 3.4.0 on both boards. The comunication works very well.
I need to install the firmware 3.1.1 because my printer has a custom firmware based on 3.1.1 version.
I have tried to install the firmware sequentially from the firmware 3.4.0 to 3.1.1.
First i update the expansion board firmware then the main board.
It's works very well from 3.4 to 3.2 then , when i update the expansion board from 3.2 to 3.1 (Duet2and3Firmware-3.1.1.zip package files) the expansion board stop working , and the status led don't blink , it seems like blocked.
Then to restore the board i have to do the hard reset (4 switches to OFF state ) and upload 3.4.0.
I don't understand what is the cause for this problem.
Can you give me a hand to downgrade the expansion board from 3.4 to 3.1? thanks -
@danielpetrea you'd be better off fixing the config to work with 3.4 rather than using 3.1.1 (it had issues with CAN-FD communication etc)
There shouldn't be anything that massively changes a config between 3.1.1 and 3.4 so what do you think wouldn't work with it? -

Hi Jay_s_uk,
Thanks for reply.
I understand but it's not only a custom config, it's a custom firmware so i need to use the version 3.1.1.
I can downgrade the main board from 3.4 to 3.1.1 and works very well, the problem is when i downgrade the expansion board from 3.2 to 3.1.1 and i don't understand the reason -
@danielpetrea it should downgrade but you will run into problems with CAN-FD comms. I also don't know whether the newer bootloader is backwards compatible
-
-
@danielpetrea it would involve the use of
S3in the M997 arguement but I wouldn't recommend downloading the bootloader, especially not to a version lower than 2.3 as there were issues with some of the timing code. And as I stated before, I also don't know whether the firmware is bootloader dependant -
@jay_s_uk i uploaded the bootloader 2.3 but when i upload firmware 3.1.1 the expansion board don't work (led status not blinking).
-
@danielpetrea i'm not sure what to further suggest then. maybe @Phaedrux can comment?
-
@jay_s_uk after uploaded the bootloader 1.3 on expansion board 3hc , the status led blinks 3 times.
Do you know what this is meaning? thanks -
@danielpetrea they're listed here https://docs.duet3d.com/User_manual/Machine_configuration/CAN_connection#led-behaviour-and-error-codes
3 blinks is Bad firmware CRC -
@jay_s_uk said in Duet3 Expansion Board 3hc blocks during downgrade:
s Bad firmware CRC
do you know what should be the cause to this error? i tried to install the firmware 3.1.1 with hard reset procedure (all swich off and then power on) but don't upload this firmware
-
@danielpetrea i don't i'm afraid. but as i've said before, all of the CAN-FD boards perform poorly using 3.1.1
-
@jay_s_uk i'm using this firmware with other machines and works well, i don't encountered CAN problems with 3.1.1.
What's the difference between Duet3 EB 3HC v1.0 and Duet Eb3HC v1.0.1 ?
Thanks -
@danielpetrea Anyone who can assit me to solve this problem? Thanks
-
Is there no way to bring the customized firmware up to date?

It sounds to me that the customised firmware for the 3HC doesn't have the CRC appended at the end of the build step.

Hi,
This error is generating when i try to upload the official release. First at all i want to install the official release then i proceed with the customized firmware. -
@Phaedrux
For this moment i'm not planing to update this firmware, i understand that is a good update but for now the timing don't alows me. I don't understand why this board is not retro compatible? There is any reason? -
Is the Duet3 currently running the Duet 3.1.1 firmware, or your custom firmware?
Can you provide a M122 and M122 B# for the 3HC when it is responding?
Can you please try uploading this zip file for 3.1.1 (as is, don't extract it first) to the system tab in DWC and allow it to update the firmware again.

At that point, what state is the 3HC in?
