I'm looking to see if I can get some assistance porting OpenWRT to a new device. The NetGate (not Netgear!) SG-1000 https://www.netgate.com/solutions/pfsense/sg-1000.html
The device was originally a PFsense appliance, but never really worked particularly well and was very quickly end-of-lifed unfortunately.
So far I've managed to get both the upstream Linux 4.19 LTS kernel and Kernel 5.4 booting on the device with (mostly) complete hardware support. Admittedly I'm very new to ARM DeviceTree so I'm a bit out of my depth on some of it. I'm able to get a "full" Linux installation running via an NFS root, so I'm able to poke at hardware reasonably easily
The device itself seems to be heavily based upon the Ti TMDSSK3358 AM335x "Starter Kit"
Right now everything works, except for
No USB or USB OTG support
No SD card support. Only internal eMMC chip is detected
Ethernet only works if both NIC's are connected to active devices. If either device is unplugged, both NIC's stop responding until both are reconnected
A NetGate developer did provide me with an old "Yocto Linux" build based on LTS kernel 4.4.3-yocto https://intelminer.com/pflin.zip
The build does seem to work and boots to a minimal ramdisk. The DeviceTree image in it also (mostly) works all the way up to Kernel 4.19 with minimal patching. Unfortunately 5.x appears to have significantly refactored the DeviceTree layout and does not work with it
If anyone smarter than me with this stuff would be able to give me some tips on where or what to look for, I'd love to do everything I can to get this device included in the project
