I don’t think that serial access will help at this point. I’ve wiped the SD card and started over, and when I boot from the SD card using the standard 4GB image, everything works fine and I can access it over Ethernet. It just won’t flash completely (it seems to flash partially, meaning that I’ve lost the initial installation). Unless having access to the serial terminal might allow me to get it to flash?
Which doesn’t bother me—leaving the SD card in is no big loss—but what does bother me is that I have to force it to boot from the SD every time it loses power (right?). Is there any way to convince it to always boot from SD without having to hold down S2?
Based on that, it looks to be a 2GB eMMC, so when you try to flash it, make sure you are using a “2GB” image, and not a “4GB” image, as that will not fit…
Okay, so when I try to boot from that, the light comes on solid for several seconds, and then goes out. And the device isn’t showing up on the network.
Thanks. I think I’ll just stick with booting from the SD card for now. Maybe I can follow these instructions to make it boot from the SD by default. Unless someone knows a better way?
