Sudden Connection Problems

Question

I tried changing a few things in the configuration.h but now octoprint constantly puts out the following error:

write failed: [Errno 22] Invalid argument' @ comm.py:_do_send_without_checksum:3490

Updating the Marlin version did not help I do have a second device named /dev/ttyS0 under the serial port tab

I also tried reflashing the image onto the pi. If I just flash it it works, but as soon as I update the marlin code it gives me the error.

Hi, this error is due to one of the file not update successfully.there are also a lot of files need to updated,so I have combined them to the new IMG files on july 16th  and have uploaded it to google drive and MEAG drive.https://github.com/markniu/PandaPi/wiki/How-to-Flash-img-&-WIFI-setup

That did work and i can connect to octoprint again.

But now only the X-Motor moves and all the others wont.

I've tried switching out the cables and drivers, but only the motor connected to X moves. I do not get any kind of error code.
