There are instructions on github for building and loading your own custom firmware, which is what I’m assuming you are trying to do here.
GitHub - Snapmaker/Snapmaker2-Controller: Snapmaker2-Controller is the firmware for Snapmaker 2.0 3-in-1 3D Printers.. I use VSCode to pack. If I have multiple firmware bins to load I do it with separate major packages, I don’t bother combining. The VSCode python pack modules has the ability to combine them, you’ll have to read through it if you need to use it.
Program compiled firmware to main controller
With PlatformIO CLI
After building, type below command in VSCode terminal
> pio run -t pack
Then you will get below firmwares in the folder (PROJECT FOLDER)/release :
-
firmware.bin: raw binary of firmware. -
firmware.elf: firmware with debug information. -
SM2_MC_APP_{xxx such as V4.0.0}_{xxx such as 20201222}.bin: minor image of module, can be used to generate major image -
Snapmaker_{xxx: version such as V4.0.0}_{xxx: date such as 20201222}.bin: major image which can be used to upgrade modules with USB stick
Finally, copy the major image to your USB stick and upgrade your machine follow the instructions in How to update Firmware section.
With Luban
You need to install Luban to package the compiled firmware.
First, Open Settings → Firmware Tool in Luban, upload the compiled firmware.bin , click Compile and Export . You will get a file with name like Snapmaker2_V3.2.0_20201117.bin , this is the packaged update file to be programmed.
Then, Update your firmware via USB follow the instructions in How to update Firmware section.
