MKS Robin Nano V1.2 Input Shaping LCD reboot loop?

Hi,

I have a Ender 3 V1, dropped in a MKS Robin Nano V1.2, and using firmware 2.1.2.1, (I also tried this with the 2.1.2.2 version, still had the same problem).

I just learned about input shaping and wanted to give it a try, however, when I try to enable input shaping in the configuration_adv.h file, the printer just gets stuck in an endless boot cycle. Been trying to search all night for a solution, seems there was a few bug fixes for SDSUPPORT for some boards, but I can't find anything explaining why when I enable input shaping that it just gets stuck in a reboot cycle where the TFT35 LCD screen (Set to the TFT_COLR_UI) just say boot, I see marlin, then black screen, then boot, marlin logo, black screen, etc ...

Anybody have any thoughts on how to fix this? I thought maybe it was RAM size, but it really doesn't seem to take up much according to the build complete info in VSCODE.

Thanks!

-Attached Config files for reference.

Hello, I have the same error
I have a Corexy with skr V1.4 turbo and lcd repreap discount.
When I load the firmware (I'm compiling it with Marlin's auto build) with Input shaper it gets stuck on the home screen, in an infinite loop.
If I comment on the input shaper lines, the firmware loads without problems.
I am loading the firmware via microSd.

2.1.2.2 is a bit of a lemon dont use it with input shaping, or a probe in the probe port that needs a pullup (ie bltouch and clones)

Thanks,

Seems to happen on 2.1.2.1 too, I suppose I can try to go farther back with input shaping, but with 2.1.2.1 and 2.1.2.2 I have the same issue.

I cannot completely confirm issue has gone away, however, switching to the original 2.1.2 version of Marlin will at least boot up and I don't get stuck in the boot loop.

Tested with 2.1.2, seems to be working, thanks for the help, wonder what is up with 2.1.2.1 and 2.1.2.2 that is not working with the Robin Nano board v1.2?

2.1.2.2 Input shaping reboot is meant to be fixed if you apply this patch [github.com]
