### Basic Information:
Printer Model: Prusa MK3s+
MCU / Printerboard:
Host / SBC
klippy.log
[klippy.log](https://klipper.discourse.group/uploads/short-url/sFsIFr4NQloYuaOIjQbOZx7TvIl.log) (73.2 KB)
_Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_
_ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _
### Describe your issue:
…I have installed Klipper and Mainsail onto the Raspberry Pi 3b. I went through the ‘make’ etc but when trying to flash the board I get an error make no rule to make target flash.
Is there another way to flash the board with the Klipper firmware?
And also is there a source for the ‘printer.cfg’ file for the Prusa mk3s+?
Many thanks and much appreciated with any help

Thank you for your reply. I tried the website that you suggested but it seemed out of date as some links wouldn’t work. I looked elsewhere where I found a similar ([Lab4450.com - Revive your Prusa Mk3s with Klipper 1/5 - Flash Bootloader](https://lab4450.com/blog/revive-your-prusa-mk3s-with-klipper-1-5-flash-bootloader/)), but it all went as detailed but still getting the same error!

See [Bootloaders - Klipper documentation](https://www.klipper3d.org/Bootloaders.html?h=avrdu#atmega2560) → you should use the respective `avrdude` commands as also detailed in the links above.

Have you seen [this](https://github.com/dz0ny/klipper-prusa-mk3s)? The configuration and instructions worked well for my MK3S+
