I'm using Tinkerboard with USB connected SATA HDD for 5 years as 24/7 server and had no similar issues with powering. The device is powered by dual USB socket power supply (1x USB to power TB, 1xUSB to power HDD via Y-USB cable). I would start with metering voltage or plugging cheap voltage monitor between power supply and TB. Try also USB power supply providing 5.2V instead of 5.0V It should also work when power is only provided to TB USB output (from external powered USB hub) I had similar issues with Raspberry Pi 3B - with similar configuration (USB 1xHDD 2,5") and main indicator of failure was undervoltage - (vgencmd indicated ) and changing power supply did not help. The only solution I've found for it was to programatically power cycle Raspberry Pi built-in USB hub every time when HDD was not available.

@ScottPthere are couple of sources for arm chromebooks, which partially support rk3288 hardware, I think there is still to come with mainline kernel 5.x if finally it will support remaining rockchip features (like mpp etc) and stabilize panfrost driver. Others obstacles were removed, and c100 (and some other chromebooks too) can work pretty well. I even could imagine some support for c100 from armbian - even as CSC, because most problems were resolved along with other 3288 issues on other boards. It's just the matter of finding interested people and basic testing.

bumping and resurrecting old thread. Looks like there is an interest to use chromebooks with linux, but most people face problems with fine tuning kernel to given hardware. I will try out hexdump's image on flip c100, and I hope this will be the first one kernel with bluetooth support for c100. Anyway if there are any news about c100 - feel free to share. I don't expect any sudden release of armbian for c100, but any suggestions how to make hardware working better with mainline kernel will be more than welcome. humble Armbian user on Tinkerboard
