[LoraWAN Gateway] BPI R2 with Debian and RAK833 over mPCIe?

I’m just about to buy this board (RAK833) to setup a LoraWan Gateway with my BPi R2. Is this possible with the 4.19.62-bpi-r2-main kernel or would I have to compile my own?

Here’s the exact Kernel I use:

root@bpi-r2:~# uname -r
4.19.62-bpi-r2-main

Maybe this helps you as well?

root@bpi-r2:~# find /sys/bus | grep spi
/sys/bus/platform/devices/1100a000.spi
/sys/bus/platform/drivers/mtk-spi
/sys/bus/platform/drivers/mtk-spi/bind
/sys/bus/platform/drivers/mtk-spi/unbind
/sys/bus/platform/drivers/mtk-spi/module
/sys/bus/platform/drivers/mtk-spi/1100a000.spi
/sys/bus/platform/drivers/mtk-spi/uevent
/sys/bus/spi
/sys/bus/spi/drivers_probe
/sys/bus/spi/devices
/sys/bus/spi/uevent
/sys/bus/spi/drivers
/sys/bus/spi/drivers_autoprobe

And finally, dmesg, where I can’t find anything… Maybe it’s just a misunderstanding and the mPCIe-Extension (RAK833) will work out of the box?

I read a the thread about SPI communication and that it is included as a kernel extension in an earlier version and I’m wondering if I need to do anything and if it will work before ordering the mPCIe Extension…

It would be my first kernel to compile, so please be kind :upside_down_face:

I have no lora,but i’ve done some changes for it for another user…don’t know if they were working

Here a dt overlay was created,but you can also add the nodes (content of overlay) to the spi0-node in mt7623n-bpi-r2.dts directly

If your device uses only pcie,i guess you don’t need to modify dts and only add driver in defconfig (maybe there is a separated item for pcie support)
