I got my hands on an SDG 8733 and was wondering how to flash openwrt. I uploaded the kernel.bin file for this router in its upgrade interface but it continues to boot its own software. The sysupgrade.bin file gets rejected by the router.
I was wondering how I would go about flashing to openwrt.
I did manage to install openwrt kernel.bin then flash the sysupgrade but I did have to use UART with the routers serial connection. I followed: SmartRG SDG-8733 gateways (also 8733a, 8734)
Sound like you figured it out, but if you run into any issues please post here. I hope to allow upgrade to OpenWrt images via the upgrade interface soon so a console isn't required for initial flashing.
Hey @linuxsys (and others). I have this device and just created an SDG-8733 device page with the install instructions I followed on it. Hopefully it helps.
