Bad command & Missing characters in Gcode since firmware upgrade

BlueDust

I assume the CRC checking is enabled by default. How do you enable/disable them?
Can you have the Duet2 log the pass CRC codes confirming it is good, and not just the failed ones?

A month or so ago, I remember having trouble uploading files with a pop up saying that the CRC failed.
I don't remember what I did to correct it, but just thought it was my slicer having issues. Happy to know this is actually a "thing" and it wasn't just me.

It's at the bottom left of the Settings/Machine Specific page of DWC 2.04.

If the CRC errors only occur if you upload while printing, then maybe we need to reduce the SPI transfer speed to the Ethernet module if you upload while a print is active, or else adjust the bus priorities.

Would be possible to somehow make the SPI speed user configurable? I've got two boards, one that I just stopped using because of this and another that only works as long as I'm not printing. Would be awesome to recover the other board and use it for something.
