Next step would be to get the Home Screen app auto started and find some way to get a "Home" button (to be able to switch between apps without completely closing them).
]]>Anyway, two things to note about the board are that the serial console uses 1.5 Mbps (which is different to the more common 115200 bps used by other boards), and uses a USB Type C connector for power (like the Raspberry Pi 4, but unlike older SBCs).
Downloading the Ubuntu image and writing it to a SanDisk Ultra 16 GB MicroSD card seemed to work fine to get it to boot. One thing I did notice was that the SSH server keys seemed to have been written to the image and not regenerated on first boot. The other thing to be aware of is that the kernel being used is fairly old (4.4.143) with mainline kernel support only starting to appear now.
One thing that appears strange to me is that total memory is only shown as "MemTotal: 432280 kB
" - I am not entirely sure what this isn't (much) closer to 512 MB.
Finally, power consumption seems to be quite good. With WiFi turned on, but otherwise completely idle, my USB tester shows the device using only around 0.2 W. Doing a "ping
" and it will go up to around 0.36 W. Reading from the MicroSD card also uses around 0.4 W. Keeping all 4 cores of the CPU busy and power consumption goes up to around 0.85 W.
On a slightly related note I have been looking at what level of support I get for my ODROID-C1 now. Unfortunately, there is still no HDMI output and no USB OTG support. Interestingly, HDMI output does work on NetBSD.
