Hello,
This board was shipped by Sercomm to the company i'm currently working at for development purposes, however it came preinstalled with an older (customized) OpenWrt version (Chaos Calmer if i'm not mistaken).
Since we really need Node.js running on it, i have to find a way to upgrade to OpenWrt 18.
Sercomm provided us with a confidential documentation of the board that was helpful enough to get most of OpenWrt 18 running on it - unfortunately i'm not sure whether i can disclose that documentation.
CPU: MT7621S
NAND Flash: 128Mbytes
DDR3 RAM: 256 Mbytes
Wifi 2.4GHz: MT7602E (via PCIe 1)
Wifi 5.0Ghz: MT7663E (via PCIe 0)
Bluetooth: MT7663E (via USB)
I made a lot of progress since yesterday and i'm happy that i got the two Wi-Fi chips (MT7603E & MT7662E) up and running. I've mapped the LEDs to the GPIO pins, same for the GPIO buttons, it's almost ready, except one thing.
The build process generates a squashfs-sysupgrade image and a initramfs-kernel and as expected, the initramfs-kernel runs just fine, however i need the configurations to persist over a reboot so i flashed the squashfs-sysupgrade and here's where the troubles started.
I've pasted the bootstrap process log starting from the kernel's effective bootstrap to the point it panics.
It seems it complaints about some magic number that's not being found by the JFFS2 system.
Am i missing a driver or the image i flashed was not packed the right way?
