BigTreeTech SKR V1.3 + Marlin V2.1.x - sh.itjust.works

I have acted recklessly and now I need help. I tried to update my Ender 3 Pro with an SKR V1.3 to Marlin 2.1 and I tried to skip some steps. I couldn’t find a v1.3 example in the configurations repo so I used a v1.4 instead because it had the right processor. I changed some stuff over but didn’t give it a thorough look and I didn’t change the SERIAL_PORT 1 and 2 settings. When I tried to load the new firmware from the SD card the screen was blank and it hasn’t worked since. The firmware file changed to a .elf so it maybe installed? I wonder if I can even load via the SD if I’ve super messed up it’s serial config. I tried some other firmware versions plus BigTreeTech’s from 3 years ago but I don’t think they’re being read. If I’ve messed up those serial configs I wonder how I could undo it without the SD card. Help… P.s. does anyone have a copy of Marlin 2.1 that works with the SKR V1.3 or the config files for that board on the Ender 3 Pro? Catch you on the flip side 😎 👉👉

Messing up the serial configuration shouldn’t affect your SD card. SD cards typically run off SPI or SDIO whereas a serial port runs off a UART or a USB virtual comm port if the processor on the board supports that. They shouldn’t affect eachother.

I would confirm your serial settings are correct, flash it using the SD card, then hook up your computer to its usb port and see if you can send/receive commands over a serial console. If you can see stuff you probably just misconfigured your display settings.

Worst case you have to buy a $5 stlink off Amazon and flash it using JTAG which is guaranteed to work unless there’s some kind of physical damage

Thanks for the info. You were right it was the display settings. Look at me getting worried over nothing.
