Can't get Ender 5 Pro up update firmware via SD Card.



  • I added a BLTouch and wanted to also get rid of the TMC connection error message on my Ender 5 Pro with the 4.2.2 silent board.

    I compiled the firmware for Marlin Bugfix 2.0 and loaded the firmware.bin onto the root directory of a fresh formatted FAT32 SD card. Everytime it generates it gives the firmware file a unique name, so don't think it's a naming issue.

    It booted up normally without any indication the firmware was loaded and I confirmed through the display it wasn't. So, I downloaded the firmware.bin file directly from Creality and same issue.

    I even had the firmware generated as a .hex file to try and load it through the USB port with Cura. When I do that it says it loses communication and fails. Although right before then I can send the printer commands just fine.

    So, what could be the issue here? I'm thinking I may have a bad board that doesn't allow me to load the firmware on it.
