STM32MP1-Old-Kits: Building Linux Userspace Applications
This application note explains how to build a Linux userspace application from the Linux-hosted cross development environment and then to deploy the built executable on the target.
On the development host, install the prebuilt Yocto toolchain from here.
Activate the toolchain:
$ source /opt/st/stm32mp1-som/2.4-snapshot/environment-setup-cortexa7hf-neon-vfpv4-openstlinux_weston-linux-gnueabi $ unset CCACHE_PATH
Now the
CC
,LD
,CFLAGS
and the others standard build environment variables are set for cross-compilation for the STM32MP1 platform, eg:$ $CC hello.c -o hello ...
To deploy the build executable to the target, copy it to a USB Flash and plug in the USB Flash into any of USB connectors on the board:
$ mount /dev/sda1 /media $ cp /media/hello /tmp $ /tmp/hello Hello from STM32MP1-SOM! $
Alternatively, you could deploy your application from the host to the target using
scp
:Another way of deploying the binary to the target is the exporting the build directory as an NFS share. Having NFS configured on your host, run on the target:
