spidev_test

[pjanco]

Hi,
I like to use spidev_test tool:

https://wiki.st.com/stm32mpu/wiki/How_to_use_SPI_from_Linux_userland_with_spidev#Installation_on_your_target

I am following this guide for compiling the tool by developer package:

https://wiki.st.com/stm32mpu/wiki/How_to_build_Linux_kernel_user_space_tools

These are commands I have used:

cd ~/Distribution-Package/openstlinux-5.10-dunfell-mp1-21-03-31/build-openstlinuxweston-stm32mp157a-visionsom-hdmi-emmc-mx/tmp-glibc/deploy/sdk

./st-image-weston-openstlinux-weston-stm32mp157a-visionsom-hdmi-emmc-mx-x86_64-toolchain-3.1-snapshot.sh 

. /opt/st/stm32mp157a-visionsom-hdmi-emmc-mx/3.1-snapshot/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

cd ~/Developer-Package

tar xfJ en.SOURCES-stm32mp1-openstlinux-5.10-dunfell-mp1-21-11-17_tar.xz

cd stm32mp1-openstlinux-5.10-dunfell-mp1-21-11-17/sources/arm-ostl-linux-gnueabi/linux-stm32mp-5.10.61-stm32mp-r2-r0

tar xfJ linux-5.10.61.tar.xz

cd linux-5.10.61

for p in `ls -1 ../*.patch`; do patch -p1 < $p; done

mkdir -p ../build

make ARCH=arm O="$PWD/../build" multi_v7_defconfig fragment*.config

for f in `ls -1 ../fragment*.config`; do scripts/kconfig/merge_config.sh -m -r -O $PWD/../build $PWD/../build/.config $f; done

yes '' | make ARCH=arm oldconfig O="$PWD/../build"

cd ../build

make ARCH=arm uImage vmlinux dtbs LOADADDR=0xC2000040

make ARCH=arm modules

make ARCH=arm INSTALL_MOD_PATH="$PWD/../build/install_artifact" modules_install

mkdir -p $PWD/../build/install_artifact/boot/

cp $PWD/../build/arch/arm/boot/uImage $PWD/../build/install_artifact/boot/

cp $PWD/../build/arch/arm/boot/dts/st*.dtb $PWD/../build/install_artifact/boot/

make tools/spi

Whole kernel build looks fine.

But the very last command "make tools/spi" have this result:

  DESCEND  spi

Where is the problem?
