ratos on prusa mini
hi everyone, I have a nice v-minion and a prusa mini and I'm happy with ratos, I wanted to try to convert the prusa mini to ratos, but between the manual and various forums, I don't understand how installing the firmware on the mini works. reference is made to an SD that the mini doesn't have (I imagine you mean USB), the card even in DFU doesn't allow me to install the firmware. Can anyone help me?

you need to break the appendix first.

Flashing custom firmware MINI | Prusa Knowledge Base
Every firmware version goes through intense testing to verify…
Yes i do this thing for go in dfu mode but if i try to flash by command line or by ratos config, have same result🤦🏻🤦🏻🤦🏻
when something doesn't work it usually prints an error, if you screenshot it there's better chance someone will know what's wrong
All right so you're gonna have to manually flash the board via dfu. That process is described in this part of the image @Prav posted although the process is a little different in RatOS. (i'm sorry about this being unmanaged and undocumented, since it's a user contribution and i don't own the printer i can't do much in terms of QA).
So before you run
make flash you're gonna need to run the ratos sscript to compile the firmware.
This is because RatOS identifies boards via custom chip_id's so it can be properly identified and updated automatically in the future (you only need to go through this process once)
So if you run
Then put your buddy into dfu mode and then run
You can confirm if the buddy boots succesfully into dfu mode by looking for 0483:df11 in the output from running lsusb
once it shows up in the lsusb, the above command should flash the board. Then power cycle everything and go through the configurator again and RatOS should register your prusa buddy.
