Or maybe Etienne can try to reproduce the issue with upstream kernel?
Building upstream kernel for Omnia and using it with OpenWRT / TurrisOS
does work, I am doing it all the time. Just take /proc/config.gz, put
it into .config of upstream Linux source, and then in make menuconfig
enable wifi drivers (since OpenWRT uses backports). You will get a
zImage which you can just replace in /boot. The modules you should put
in /lib/modules/KERNELRELEASE (all *.ko files directly in this
directory, without the directory structure created by make
modules_install). Basically
On omnia:
zcat /proc/config.gz
and copy the output to linux/.config
In linux/
ARCH=arm CROSS_COMPILE=arm-none-eabi- make menuconfig
enable wifi drivers in menuconfig and then
ARCH=arm CROSS_COMPILE=arm-none-eabi- KERNELRELEASE=6.3-rc2 \
make zImage
copy arch/arm/boot/zImage to omnia /boot
ARCH=arm CROSS_COMPILE=arm-none-eabi- KERNELRELEASE=6.3-rc2 \
make modules
ARCH=arm CROSS_COMPILE=arm-none-eabi- KERNELRELEASE=6.3-rc2 \
make modules_install INSTALL_MOD_PATH=MODS
mkdir MODS_FOR_OPENWRT
find MODS -name '*.ko' -exec mv {} MODS_FOR_OPENWRT \;
rm -rf MODS
and copy the *.ko files from directory MODS_FOR_OPENWRT to omnia,
directory /lib/modules/6.3-rc2
