I have decided to bring up my 820c board. Before doing anything I plugged it in and checked that it was working, check. Holding the volume key and applying power takes me to Fastboot, so I should just need to load a new boot and rootfs and away I go…
So, I loaded the boot and roofs from the latest snapshot #297 http://snapshots.linaro.org/96boards/dragonboard820c/linaro/debian/297/ and sure enough the board sort of comes up, but it doesn’t get to the debian screen. Hmmm, maybe I need a new aboot and boot loaders, so using the flashall script I installed #43-linux from https://snapshots.linaro.org/96boards/dragonboard820c/linaro/rescue/latest/. This didn’t help.
Next I loaded snapshot #220 (with aboot from #43) and it comes up with no problem, so somewhere between #220 and #297 something changes. after many reflashes of boot and rootfs I have determined that the issue comes in between snapshot #222 (works great) and snapshot #223 (bad).
The console output for #222 is here: https://pastebin.com/Y4x5eGpe
On first boot after loading #223 it eventually comes up (takes over 600 seconds). See https://pastebin.com/CKL2V8S3 but if I reboot it doesn’t come up (or at least not in the 1300+ seconds I was willing to wait), see boot log here: https://pastebin.com/Cu2x1A9U
I looked at the build changes for #223 and a lot of packages have changed, as well as the kernel, from #222. http://snapshots.linaro.org/96boards/dragonboard820c/linaro/debian/223/
What infrastructure in the UFS have I missed changing to get the later snapshots to work?
Thanks in advance for your help.
