Hi

I wanted to update my Klipper firmware on the MCU. I configured everything correctly using

make menuconfig, as described here: Klipper (MOD) - KobraGoNeo Insights

Then I ran a make to get the klipper.bin file, which I renamed firmware.bin and copied to the SD card.

I then turned off the printer, inserted the SD card, turned on the printer, and waited 10 minutes.

I then turned off the printer and restarted the Klipper firmware in mainsail, but it’s still running the old firmware version 0.12. What’s the problem?

Try renaming the file to something you never used before, e.g. firmware1.bin

Hi

I tried, unfortunately without success.

Typically, such an issue is caused either by:

  • Boot-loop protection on the board, i.e., reusing the same filename
  • Wrong filename scheme
  • Wrong firmware settings during make menuconfig
  • Bad SD-card

I do not know this board well, so maybe @Catnippr has an idea.

Generally speaking, those TG mobos seem to be quite picky with the mSD cards, so I’d try different cards, preferably small cards, nothing bigger than 8GB for flashing.

Besides, just wondering @Sineos: does one have to keep the printer’s fw updated as well if there haven’t been any changes for that specific mobo one is using?

Not at all. The majority of changes only affect the host side, and Klipper will actively raise an error if there is a discrepancy between the host’s capabilities and the firmware’s capabilities. This then indicates the need to upgrade. Simply “following along” has no added value.

Such changes that necessitate a firmware upgrade are not specific to a particular board but instead affect general MCU hardware, functionalities, features, or certain MCU families.

That’s great, thanks!

Edit: means, if OP’s Kobra Go works just fine with the current Klipper version, then there’s no real need to update - so if flashing somehow doesn’t work now or OP doesn’t have/wanna get different mSD cards to try it out, then everything should still be fine.

Thanks for the help, but there is still a problem: if I want to use an ADXL chip for input shaper, it won’t work because the current Klipper version doesn’t match the version of the MCU.

This means I cannot perform an input shaper test.

So I have no choice but to get another SD card that is 2 or 4gb in size
