Update:solved. Downloaded the firmware for the wrong board.
I have an SKR Pro 1.2. Is there a comprehensive installation write up anywhere? I tried to update my firmware tonight and now in Marlin mode it just says Marlin Mode and doesn’t show X,Y,Z or menus or anything. In touch mode I can navigate through the menus but the steppers don’t respond. It was working before the attempted update.
I was installing the firmware for dual endstops. They’re not hooked up yet. Could that cause this behavior?
Attached is pic in Marlin Mode. In touch mode it says no printer attached. It seems the screen isn’t seeing Marlin in the SKR board. Also the info screen.
As a first step, I’d reflash the board. Start as clean as you can…fresh download of the firmware from V1 and different SD card, and make sure the SKR Pro is off when the card is inserted. The TFT has its own firmware, so having the menus displayed in TFT mode means nothing in terms of the SKR Pro board.
If you still have the SD card you used to flassh the board unaltered, check the filename of the binary. If the SKR Pro thinks it successfully flashed the board, it will rename the binary.
Thanks for the reply Robert. The file has been changed to CUR so it thinks it flashed the board. My concern is I’m not sure there’s any firmware on the micro sd card. I download the file, then I copy the firmware.bin file to the sd and power up the SKR. Do I need to unzip the downloaded file to a particular location, or is the only thing the SKR wants is the firmware.bin?
Now that I think about it, another possibility that matches closer to your issue is that you downloaded a firmware file for the SKR instead of the SKR Pro.
The firmware only wants the firmware.bin. There is no other magic or steps. My only thought is that the firmware.bin has been corrupted somewhere along the line. I’ve not seen your problem before on the forum. So assuming it is being corrupted:
Bad in the ZIP on the repository
Bad ZIP download
Bad unzipping the file from the ZIP file.
File issue with the harddrive it is being unzipped to
Issue with the SD card
Issue with SD card reader on the SKR Pro
There are things you can do to test/eliminate each of these. I don’t have an SKR Pro board, but I believe it has a USB connection for a memory stick. Perhaps it will flash from the stick to eliminate SD card issues.
