Katapult flashing issues on SKR E3 V2

General Discussion
1

I see this post is old but I’m hoping someone will be able to help me. I have flashed katapult onto my skr e3 v2.0 board and it will not show up when connected to my pi4b unless it’s in bootloader mode. When I try to flash Klipper onto it in bootloader mode it is failing every time, I have ensured that I followed the settings above and have looked in other threads and found nothing that works. If there is more information that I should attach please let me know.

If the device is already in bootloader mode it can be flashed with the
following command:
make flash FLASH_DEVICE=1eaf:0003
OR
make flash FLASH_DEVICE=1209:beba

If attempting to flash via 3.3V serial, then use:
make serialflash FLASH_DEVICE=1eaf:0003

Please don’t hijack an older thread.

Could you start a new request in “General Discussion” as this is definitely not a discussion for “Configs” with all the requested information. This includes your hardware set up including what is the host that you are using as well as a host and your klippy.log.

Looking at your comments above, you should explain how you loaded Katapult onto the SKR Mini E3 V2.

You appear to be using a wrong flash command:

Please pay particular attention to step 8 of my instructions:

Flash Klipper onto the modified SKR board using the standard flash command make flash FLASH_DEVICE=/dev/ttyACM0. Make sure to use the correct device name for your specific installation, for example it could be make flash FLASH_DEVICE=/dev/ttyACM1, etc.

When in doubt, please consult the official Klipper installation instructions.
