it gets really weird when doing echo "hello" > /dev/tty1 - the on-screen display is rather... garbled. i'll try a 3rd CPU Card later, and/or perhaps set up dual-output (via HDMI) to check that it's not the framebuffer that's corrupted. > Now if only the established players would see sense and support this effort > instead of dumping excess stock SoCs into newsagents on the covers of > magazines and causing scuffles in the aisles. :-/ yehhh you saw the report a few days ago by Make magazine, which showed that the cost of that $5 board is considerably higher: "Solving this lack of connectivity makes the cost of owning a Pi Zero increase greatly. It’s not just that you need a USB Wi-Fi dongle, you’d need a powered USB hub to have a Wi-Fi dongle, keyboard, and mouse (it only has one USB slot for peripherals; the other is for power)." http://makezine.com/2015/11/28/chip-vs-pi-zero/ further down, it shows that the only thing you need to operate the C.H.I.P is a $1 USB cable, to provide power. the alternative board - which is "only" $5 - requires a whopping *$19* of additional components in order to make it actually useful. l. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
