@crispyoz I would order Omega2+, the 32M/128M. In fact, I read that the (+) is the recommended model for development. Still, could procure only Omega2 locally. Digikey would take take 2 weeks or so. Finally, plan to use the SMD version, with custom PCB and power. Though I was able to boot RPi Zero W with cross-compiled OpenWRT 18.06.8 last week, Omega2S(+) will be easier from the hardware perspective. I am happy with the progress made in the past few days. Really appreciate all your help.. Thanks again.
