OpenWrt/LEDE feed containing packages (mostly LoRaWAN). There's a lot of SPI problems with the Linkit Smart 7688, so this won't run without some kernel patching - https://github.com/narioinc/mt76xx-spi-half-duplex-patch/. As such, I built my own openwrt based firmware from scratch and then uploaded it to my linkit. I needed this patch because any chunks greater than 16 bytes would cause a kernel panic (viewable by dmesg); as such the various lora gateway tests for spi were failing (https://docs.labs.mediatek.com/resource/linkit-smart-7688/en/limitations-and-known-issues).
I'm currently running the spi bus at 2MHz (within the lora gateway package) as I had concentrator start issues at 8MHz and 4MHz. The legacy packet forwarder appears to be working fine. The multi protocol packet forwarder recieves RF packets and forwards upstream fine, but seg faults on downstream packets (packets from the network server). It also seems to have a lot of unintended SX1301 resets -- I'd advise not attempting to use this and just sticking to the legacy packet forwarder.
