## CAN Frequency Switching
|
|
|
|
First, connect to the host computer.
|
|
|
|
Recompile the firmware for the CAN communication device (U2C or Can Bridge) directly connected to the host computer and set the frequency to 1M to communicate with IDM.
|
|
|
|
Use the following command to query IDM's UUID:
|
|
```bash
|
|
~/klippy-env/bin/python ~/klipper/lib/canboot/flash_can.py -q
|
|
```
|
|
|
|
Download the required frequency IDM firmware and canboot overlay firmware from the cloud drive.
|
|
|
|
Execute the following command:
|
|
```bash
|
|
~/klippy-env/bin/python ~/klipper/lib/canboot/flash_can.py -f <path to canboot update firmware> -u <UUID obtained>
|
|
```
|
|
For example, `<path to canboot update firmware>` could be ~/Canboot 1M.bin. Fill in your data and remember to remove the `< >` brackets.
|
|
|
|
Wait for the execution to complete, then enter:
|
|
```bash
|
|
~/klippy-env/bin/python ~/klipper/lib/canboot/flash_can.py -f <path to new frequency IDM firmware> -u <UUID obtained>
|
|
```
|
|
For example, `<path to new frequency IDM firmware>` could be ~/IDM_CAN_8kib_offset_1M.bin. Fill in your data and remember to remove the `< >` brackets.
|
|
|
|
If you want to switch to USB communication, you can flash firmware with the USB label using the same method and solder the mode-setting jumper on the back of IDM to the side with USB.
|
|
|
|
## If you are currently using USB firmware and want to update or switch to CAN mode:
|
|
|
|
```bash
|
|
cd ~/klipper/scripts
|
|
~/klippy-env/bin/python -c 'import flash_usb as u; u.enter_bootloader("<your device serial port address>")'
|
|
cd ~
|
|
~/klippy-env/bin/python ~/klipper/lib/canboot/flash_can.py -f <firmware path> -d <your device serial port address>
|
|
```
|
|
|
|
The device serial port address refers to the address in the format /dev/serial/by-id/****. Please note that the serial port number for the second time should be different. Re-query it.
|
|
|
|
Fill in your data and remember to remove the `< >` brackets.
|
|
#### via DFU
|
|
if you managed to get your idm into dfu mode,
|
|
you can use the command below to upload canboot,
|
|
please note that this method is only applicable to canboot with usb communication.
|
|
if you are trying to upload canboot for CAN version,please use the second one(the command for main Firmware).
|
|
```
|
|
sudo dfu-util -d ,0483:df11 -R -a 0 -s 0x8000000:leave -D <Where The Firmware Is>
|
|
```
|
|
and the command below to upload main firmware
|
|
```
|
|
sudo dfu-util -d ,0483:df11 -R -a 0 -s 0x8002000:leave -D <Where The Firmware Is>
|
|
```
|
|
Fill in your data and remember to remove the `< >` brackets.Please note that these two commands are different |
