Software Reset whilst printing 3.2-1 Beta

[jay_s_uk]

@dc42
I left the printer on all night and did not have a reset.
However, I was printing a file this morning and complete access to the SD card was lost.
DWC reported that the file being printed was unreadable with an error code 1.
I was then unable to home the machine etc. I also attempted to re-read the SD card using M21 but DWC reported the card as unusable.

M21
Error: M21: Cannot initialise SD card 0: Card is unusable
Failed to get file list
Target drive is unmounted

After that, DWC started to complain that it couldn't write to its json file. All that was left was to reset the machine, at which point the SD card was available again.
Below is an output from M122 when the SD card was unusable but I'm not sure it tells you much.

Just had it lose the SD card whilst sat idle as well. Popping the SD card out and putting it back in give the same errors as before. M21 also doesn't work.

[jay_s_uk]

had another timeout that seemed to happen somewhere around the 45 minute mark. I will revert back to the other previous build for the moment

[dc42]

Thanks, it looks like resetting the SDHC controller isn't enough to clear the error when it occurs.

To restore access to the SD card, did you need to power down, or was a software reset (or the reset button) enough?

[jay_s_uk]

Using the reset button was enough. I didn't try an emergency reset

[jay_s_uk]

@dc42 Is there another build you would like me to try?

[jay_s_uk]

I've switched to SBC mode at the moment.
I can't have the 12864 display enabled though as it just constantly resets

@jay_s_uk said in Software Reset whilst printing 3.2-1 Beta:

If you think there is a problem with the 12864 display driver, please start a new thread about that.

Regarding the original problem, I have been assuming it is the internal SD card that you were referring to. Please confirm.

[jay_s_uk]

@dc42 yes, it was the internal sd card with the mini 5+ in standalone.
The reboots were becoming quite erratic, hence the switch to SBC

[jay_s_uk]

@dc42 I tried the updated firmware linked to in the other thread and managed to print a file, with the machine being left on after that.
On the second print, the SD card was lost again and the board did not reconnect.
I tried connecting to it via USB but I was not getting a response so I was unable to obtain an M122 output.
DWC also didn't connect and I got the HTTP rejected error.
Here is an M122 output after repowering the machine.
