Klipper build problem

[sabankaradeniz]

Hello,

First of all, thanks for sharing. When I try to build frimware in Klipper as you show in the guide. I'm getting an error. I am using Arduino Uno + Cnc Shield as card. On the Arduino Mega processors, I do not have any compilation problems.

same problem，hope somebody can fix it or share some successed firmware

Klipper3d/klipper#4938

The problem is that avr toolchain that comes in the latest ubuntu/raspberry pi packages is buggy.
Possible solutions are to use a toolchain version from the older OS releases (easier, described in the comments of issue above), to build and install a more recent toolchain (hard, also slow to build on RPi), or to use MainsailOS.

Btw somebody can build newer toolchain packages and publish them so others can just download and install. Building gcc is not an easy task, especially if building for another architecture (building for arm on a x86_64 host).

Hope someone will find it useful here is a hex file I compiled today on off the master branch of the 328p. I was able to compile and install it on a virtual box image on ubuntu 18. something was messed up with the version I built, it wouldn't install properly. I ended up finding this compiled version from Janurary: https://gist.github.com/kirill578/b9ac61f4df8c7ce80a17eebd76691649

hello i also have the same problem how do i convert to .hex file?

I really don't understand why #4938 had to be locked, this is poor form to say the least :\

In any case, I report that I was to implement the buster rollback for gcc

fix as per Klipper3d/klipper#4938 (comment) by orobardet

I'm on debian 12 on x86, running kiauth for klipper management

Add the line of text to /etc/apt/sources.list

deb http://deb.debian.org/debian/ buster main contrib non-free

then added text to /etc/apt/preferences.d/avr-buster

Package: avr-libc avrdude binutils-avr gcc-avr
Pin: release n=buster
Pin-Priority: 1001

then

apt update 
apt install avr-libc avrdude binutils-avr gcc-avr

went back to ~/klipper

Perhaps there is still some fat that can be cut off.

I would be happy with a klipper that only has heater controls, or only has stepper controls, or only acceleromater, or maybe even only endstop+rgb+fan

I will try removing the following and see what we're left with.

out/src/spicmds.o
out/src/i2ccmds.o
out/src/pwmcmds.o
out/src/stepper.o
out/src/avr/adc.o
out/src/avr/spi.o
out/src/avr/i2c.o

36K, still overweight by 10K
Same .config as above but I modified src/Makefile as follows

src-y += sched.c command.c basecmd.c debugcmds.c
src-$(CONFIG_HAVE_GPIO) += initial_pins.c gpiocmds.c stepper.c endstop.c \
    trsync.c
#src-$(CONFIG_HAVE_GPIO_ADC) += adccmds.c

#src-$(CONFIG_WANT_SOFTWARE_SPI) += spi_software.c
#src-$(CONFIG_WANT_SOFTWARE_I2C) += i2c_software.c
#sensors-src-$(CONFIG_HAVE_GPIO_SPI) := thermocouple.c sensor_adxl345.c \

#src-$(CONFIG_WANT_LDC1612) += sensor_ldc1612.c
src-$(CONFIG_NEED_SENSOR_BULK) += sensor_bulk.c

Plus I modified this section of /src/avr/Makefile

# Add avr source files
src-y += avr/main.c avr/timer.c
src-$(CONFIG_HAVE_GPIO) += avr/gpio.c
#src-$(CONFIG_HAVE_GPIO_ADC) += avr/adc.c
#src-$(CONFIG_HAVE_GPIO_SPI) += avr/spi.c

src-$(CONFIG_AVR_WATCHDOG) += avr/watchdog.c
src-$(CONFIG_USBSERIAL) += avr/usbserial.c generic/usb_cdc.c
src-$(CONFIG_SERIAL) += avr/serial.c generic/serial_irq.c

maybe some combination of removing endstop, debugcmds, stepper, trsync ... there might be something to get under that 27K limit ...

My hope was actually to find a configuration to get below 10K and control just two stepper driver or just one heater+thermistor, that would be perfect for my goal of a CH32V003 (0.30$ 48MHZ risc MCU with 16K) plus a W5500 ethernet driving only steppers or heater. but it might not possible at all.

Many thanks to the contributors to this thread to date.
Using 32bit bookworm on a Pi Zero W (not a Zero 2), I have, running Klipper installed using KIAUH, successfully compiled/linked the image for an Arduino UNO without having to revert to the buster version of the tool chain.
To achieve this, did require some trial and error editing the .config file for the very simple hardware required, just 2 steppers and a servo motor, making up a drawbot. Note that the image has not been flashed to the Arduino nor tested yet.
However, it has been possible at least to build the image using just the 32bit bookworm and the tool chain in that release.
