Describe your issue:

Cannot make firmware, comes up with errors
Sorry, new to Unbuntu and Klipper.

First issue is you have a modified version of the C file needed to build the firmware for your board. You need to revert to stock Klipper and try it again.

Git version: 'v0.12.0-180-g79930ed9-dirty'
Modified files: src/stm32/stm32h7.c

OK, that was installed from kiauh
Do I need to uninstall Klipper and re-install with kiauh or install Klipper from git?

I’m going to uninstall and re-install with kiauh and see what that does.

Uninstalled everything, re-installed everything using kiauh.
Same problem.

Do me a favor and run

arm-none-eabi-gcc --version

I think your build environment is getting confused somewhere, It’s trying to build with a bunch of different system calls it shouldn’t be.

6

arm-none-eabi-gcc (15:13.2.rel1-2) 13.2.1 20231009

7

Nothing after that? Like this…?

If not I think you’re trying to build with standard GCC which doesn’t have certain binaries needed for building for embedded systems.

Confirm for me that there is no text after your arm gcc version though first.

This in on a Lenov mini pc with AMD R7 processor

10

Try this…

sudo apt update
sudo apt install libnewlib-arm-none-eabi
sudo apt install binutils-arm-none-eabi
sudo apt install gcc-arm-none-eabi binutils-arm-none-eabi libusb-1.0 pkg-config

Those should have already been installed when you installed Klipper but I think you’re missing newlib at the very minimum.

After that try reflashing

Same problem trying to make

13

Is your board the H723 of H743 version?
And will you be using CAN or USB to connect?

You’ve got a GCC discrepancy somewhere but I’m no build system expert, easier for me to just compile the firmware for you and drop it here.

Kevin or someone more knowledgeable than me might drop along and fix the core issue, but I can get you up and running before then.

14

Please put such (long) code snippets between Preformatted Text tags!
That keeps the posts/thread more readable and clear.

H743 and usb

Thanks

Here you go, Let me know if it doesn’t work for some reason.

IIRC we have to use newlib v4.2 at most to compile current Klipper. I had the issue a couple days ago and had to downgrade.

18

OK, how do I downgrade to the 4.2 version?

19

It doesn’t show up on USB port
With Marlin firmware in it, it will show up by port or by ID
With the Klipper firmware it won’t show any ports or ID’s

I also have the BTT TFF50 touchscreen, it’s blank.
From what I understand it should show a menu in Marlin emulate mode from the BTT screen configuration.

It’s taking the firmware and saving it as .CUR file but acts doa. BTT had a two year old Klipper firmware on their site that acted the same. I assumed it was because the versions did not match up.

20

Which Ubuntu version are you using?

Generally speaking:

  • KIAUH installs all required packages to successfully compile and run Klipper on Debian-flavored Linux OS, e.g. Debian, Ubuntu, Armbian etc
  • If it does not, then something is very likely amiss on OS level
  • Personally, I would not try to continue until this is fixed. A corrupted OS can create so many reasons for the whole system to fail that a proper diagnosis is virtually impossible.
