' Not a valid input pin' after upgrade

General Discussion
1

HI, Been using Klipper with my Sidewinder X1 for about 8 months and it has been working great.

Today I upgraded the software and now the MCU shutsdown immediatly and the klippy log has the following messages in it.
“Transition to shutdown state: MCU ‘mcu’ shutdown: Not a valid input pin”
and
“error: MCU ‘mcu’ error during config: Not a valid input pin”

This was working fine before the upgrade, and I even had the BL-TOUCH configured and working.

I have checked through the config to make sure there was no typos, and double checked the pins, Can anyone suggest a way I can determine the problem pin as the klippy.log file doesnt help.

printer.cfg (4.4 KB)

klippy.log (27.0 KB)

This is the printer config from my sx1, and it works fine

Thanks, but I get the same message with your config… had to comment out the include statements but it still gives me the same message.

I would be curios to see what you have done in the included files though if you dont mind sharing.

4

I Post the files when i’am home.

Have you restarted the pi?

Note That i Have the pi as second mcu and the mcu is connected by uart

5

Yeah, restarted and even turned everything off.

Reverted back to the last commit of April and it works again. I Would still like to resolve this so I can move forward.

6

Did you compile and flash the MCU’s firmware after upgrading? Looks like there’s some room for improvement in the error reporting…

7

Flashed it, installed the new Host software. Same process I used to revert back.

Yeah, it looks like the code just goes into shutdown without any meaningful reporting. I took a look to see if I could work it out but the code just uses an unsigned int, and I could not see an easy way to determine the pin that was the problem.

8

It looks like there was an error in a recent commit. Hopefully it should be fixed now (commit 7fddc5a8).

Do you want the configs regardless?

10

Yes Please. I want to try a few things you appear to have working

Thanks

Thanks, I will try again and let you know if it didn’t fix it.

@koconnor That fixed it. Thanks
