Connecting the board and bring it into flash mode

Step 1: Connect 24V (Power on the board)

Step 2: Connect USB-C cable to your Klipper device (usually Raspberry Pi)

Step 3: Push and hold the BOOTSEL button

Step 4: Push the RST button and hold 0.5 seconds

Step 5: Release the RST button, after 3 seconds, Release the bootsel button

Verify your device is in boot mode connected by running the following command:

lsusb

The output should contain an entry looking like 2e8a:0003 Raspberry Pi RP2 Boot

Flashing the firmware

Now we do not flash the fimware by directly copying it to the storage, but we flash it using the following command:

make flash FLASH_DEVICE=2e8a:0003

The output looks like the following - IF you are prompted (you might or might not) for a password, enter the password of your current user account.

Now restart your fystec-erb by disconnecting 24V - waiting some seconds and reconnecting 24V again. You should be able to see it as usual klipper device within

ls /dev/serial/by-id

Configuration

See ercf_hardware.cfg in this repository config folder.

Known issues

The mark of GPIO24 and GPIO25 is swapped, check the silk file here.
