3HC Boot Issues
-
I attempted adding a 30 second delay using G4 and still have had no luck.
-
@flavamuffin Did you try 3.3 beta 2?
-
@pkos I have yet to try that that. I will later today and see if it remedies the problem.

If you install 3.3beta2 on the expansion board, you will also need to use 3.2beta2 on the main board, otherwise you will get only partial functionality.
A symptom of the slow startup issue is that after powering up the 3HC, the red LED stays off for a noticeable period of time, several seconds or more. Do you observe that?

@dc42 I have updated to 3.3beta2 on both boards and the problem still persists. I presume the red LED you are referring to is the diagnostic one by the RJ11 ports. That one remains off for roughly a minute after startup. Before updating from 3.2.2 to the 3.3beta2 it immediately started flashing in time with the main board once lit. Now it flashes rapidly for about 1 second after it initially lights up before flashing in time with the main board. If I am wrong in my presumption about which LED you are referring to, and you do mean the one on the corner of the board next to the other LEDs; that one turns on immediately.

@flavamuffin thanks, I did mean the LED between the CAN ports. Which country are you in?
-
@dc42 I am in the USA.

@flavamuffin, I am still trying to track down what causes this slow startup issue on a few boards, but unfortunately I still do not have a board that exhibits this issue. So I am having to make guesses about what is causing it.
Please can you try the Duet3Firware_EXP3HC.bin file at https://www.dropbox.com/sh/dupd9u1xppr1om5/AADYg4guuj2n8LJokVqtK-C7a?dl=0. This should identify itself (using M115 B1) as "Duet EXP3HC firmware version 3.3beta2+2 (2021-04-16 07:53:14)".
If that firmware still shows the slow startup issue, please try the firmware at https://www.dropbox.com/sh/fgpjmta9fut21gb/AADgv9v7MRqywjFj9vOXLvOra?dl=0. This should identify itself as "Duet EXP3HC firmware version 3.3beta2+2-12MHz (2021-04-16 08:04:22)".
If that also exhibits the slow startup issue, please contact your supplier to have your board replaced under warranty.
By "slow startup", I mean that after applying power the red LED between the CAN connectors takes longer than about a second to start flashing.
Do not attempt to update the bootloader on your EXP3HC.

@dc42 Firmware version 3.3beta2+2 did not seem to have any effect on the problem. Version 3.3beta2+2-12MHz seems to have worsened the issue. It causes the board to take several minutes to initialize. I am going to start an inquiry with my supplier about replacing the board.
-
@flavamuffin, thanks for trying those. I authorize a warranty replacement for your board.

@dc42 Thanks for all your help! I hope you end up finding the cause for the issue.
