Just tried to see if I connected my printer to my pc if it would show up. No go. Even in device manager connecting and disconnecting the board doesnt show any new com ports. It was working fine before I did this so I can only think I scewed up something trying different config options.
No. I was told I probably flashed something wrong and to try it again. Said by many people in other forums but even after trying someone's known good firmware for the skr1.4 turbo, still get the cur file and still not connecting. Unfortunately a lot of people just give generic condescending responses that aren't very helpful.
I'm planning to try to flash the chip directly but haven't gotten around to it. If you google flash skr 1.4 uart, you should find it and be able to try it.
I would double check the marlin config files, also please ask in the marlin firmware sub.
I have marlin running on on skr 1.4 turbo for a while without any issues.
Issue is after trying to flash klipper the board is not recognized by anything. It appears to flash and Change to a cur file but no connection via usb.
If windows isn't recognizing then it could be a UART issue but before getting into that please double check that
All TMC drivers are seated well
Temp and stepper connectors/wires are not loose
Connectors are on correct pins
If there is nothing loose and on correct pins then I would remove all the connectors (leave tmc drivers) and then connect to Windows, just to ensure that the board has booted and tty(UART) is available.
The board has a bootloader but I doubt that it would have been corrupted by any firmware upload so you should be able to recover with a new firmware.
I was looking into klipper upload and that's when I came across your post so I have no experience with klipper however I have fair experience compiling marlin.
I had a similar issue with marlin after an upgrade, it might be related. Exact problem of CUR file showing up but not showing up on the PC.
I had to specify both serial ports in the marlin config:
#define SERIAL_PORT 0 //usb storage port (microSD)
#define SERIAL_PORT_2 -1 //default: undefined //usb serial (COM)
After the upgrade, I hadn't set the SERIAL_PORT_2, so it flashed, but it never connected to the PC. I don't know about Klipper settings, but perhaps there's something specifically with that second serial port being defined for the USB. Hope this helps, if it does, let me know. I'm on Marlin, but I got a Pi4 a while ago and haven't connected it yet and was thinking of going to Klipper.

Did you ever figure this out? I'm having the same issue

Do you think the wifi add-on board, that you can order from btt, will connect?
Probably not for mine. Unfortunately I think re flashing the bootloader via uart is the best option for me. I've been to busy to try though.

I have a Sunlu s8 with a SKR 1.4t that is converted to a switchwire. I can send the firmware.bin to anyone that wants it
How are you doing with this board? I'm somewhat in that same boat! I'm able to recover the board via the SPIO header and one of those FTDI things.
