Spider v3.0h7 not working after flashing klipper.

[vdelephimne]

Ok.
I have tried everything in the guide at least 5 times and nothing works.
Flashing seems to be fine file uploaded 100% I never get a connection after restart. No serial device listed /dev/serial/
I tried by SD card no change and yes, I re-flashed the bootloader per your instructions, I purchased your voron v2.4 kit hoping it would not be this much of an issue to get working. Your documentation is not the best I have seen. I am going to await your response and resolution to this issue.

you need to link this in your spider GitHub or your sales material on the H7 https://github.com/FYSETC/FYSETC-SPIDER-H7
Took me 2 days of trial and error because all I had was the reference for all you other spider boards. I found that by accident in a Google search. H7 has a different processor than the spider 3x
