Pogoplug V4 fails to boot 4.12.8 (1 reply)

I'll start by saying that whoever at Cloud Engines eliminated the "Enable SSH" option should be staked out in the warm, friendly sun to concentrate their sugars for the benefit of our hard-working friends, the ants. Connecting to the serial header on the V4 is a colossal annoyance. Then I went through three USB-to-logic-level serial adapters before finding one that the Pogoplug would condescend to speak to, all the time wondering if I'd fried the board while wiring on the serial port vias.

But I got the new u-boot loaded in, and then as usual everything went straight into the outhouse. I cannot get this board to boot any of my known working images for the E02, and I can't get it to boot the 4.12.8 distributed either. For the E02 images it hangs right after "OK, booting the kernel" and for the 4.12.8 it simply whines that it can't get the kernel image.

I have a working E02 which I'm using to generate the images and boot drives for the V4.

That said, here's the background.

This is pretty much a standard environment as distributed, with the exceptions
of dtb_file, load_dtb and machid.

==================================================================

/boot/dts/kirkwood-pogoplug_v4.dtb must be there; I generated the new uimage from it.

Suggestions will be gladly received.
