run armbian on 64MB ram?
I wonder how much ram is consumed by kernel, system services and tmpfs on a typical armbian system? Rockchip rk3308G has 64MB ram packaged in cpu. A dirty cheap 4 layer board could have a cpu, a few discrete power chips, a mmc card slot, and a wifi/bt module, with a bunch of low speed io and two usb 2.0 port, one host and one otg. The cpu is quad core cortex A35, powerful and power efficient, compared to Pi Zero W or BBB.
Does that sound interesting for an iot node? Or it is too cri
The chip is targetted on smart speaker market, according to rockchip guys. They have a SDK based on v4.4 kernel and build root, with a lot of voice/audio processing packages. Probably 32 bit system recommended. I don't know whether zram could help a little on memory constraint or doesn't help at all. I will give it a try when I have a board.
Both rk3308 and its G variant have similar cores/performance to Allwinner A64/R18, but they are cheaper and easier (built-in ddr2 or 16 bit ddr2
