💾 portentax8-x8h7

This repository contains the kernel modules for interfacing with various IO devices via a special firmware running on the STM32H747AIIX/Cortex-M7 core.

This driver compiles against linux-imx:6.1.24.

Build/Deploy/Install

• Edit conf/auto.conf (vim conf/auto.conf)

# Extra options that can be changed by the user
-INHERIT += "rm_work"
-INHERIT += "buildstats buildstats-summary"
-INHERIT += "buildhistory"
-BUILDHISTORY_COMMIT = "1"

+#INHERIT += "rm_work"
+#INHERIT += "buildstats buildstats-summary"
+#INHERIT += "buildhistory"
+#BUILDHISTORY_COMMIT = "1"

• Clean the global state and rebuild x8h7 module

bitbake x8h7 -c do_cleansstate && bitbake x8h7

• Search for x8h7 kernel module location (find . -maxdepth 4 -name x8h7) within build folder (i.e. build-lmp-base)
• Rebuild x8h7 kernel modules with bitbake -c do_compile (force the compilation or configure with the modifications you just did in WORKDIR) (and withouth -c do_cleansstate)

bitbake -c do_compile -f x8h7 && bitbake -c do_install x8h7

• Copy files to Portenta X8

adb push deploy/ipk/portenta_x8/x8h7_0.1-r1_portenta_x8.ipk /home/fio

adb shell
cd /home/fio
sudo opkg install --force-reinstall --force-depends x8h7_0.1-r1_portenta_x8.ipk

or

adb push ./tmp-lmp_xwayland/sysroots-components/portenta_x8/x8h7/usr/lib/modules/6.1.24-lmp-standard/extra/*.ko /home/fio
adb shell
sudo rmmod x8h7_can
sudo mount -o remount,rw /usr
sudo mv *.ko /lib/modules/6.1.24-lmp-standard/extra/
sudo modprobe x8h7_can
