Accurate summary. > It is also my understanding that the recommended bootloader for > Freerunner is Qi and not u-boot. Well, that's a questionable recommandation. > The Freerunner appers to still be on sale, are new phones shipped with > a broken u-boot? When users get their Freerunner, do they typically > get a firmware update which will flash a new bootloader (Qi or u-boot)? As far as I know, all GTA02 phones are shipped with a broken u-boot. This may not be the case with the forthcoming GTA04 model. It should be a good thing to check before the GTA04 is mass-produced. When users get their Freerunner (GTA02), they can do whatever they want, including switching from u-boot to Qi. However, the "backup" bootloader remains a broken u-boot. > As I understand it, it's really easy to flash u-boot on a Freerunner, > and while it's not something we should be done lightly, it seems to > have been done in a relatively safe way, and there is only a little > chance that you would brick your hardware. Indeed. Plus, unless you somehow manage to overwrite the NOR u-boot, your device isn't really bricked, as you can enter NOR u-boot by holding AUX while booting. > My preference would be for Debian to: > * communicate on this u-boot bug and point at Qi/updated u-boot > binaries and at http://wiki.openmoko.org/wiki/NeoTool to flash it > (we should package it?)

I don't think we can make it much easier. Furthermore, the installer should rely on the bootloader that's available on all GTA02: the u-boot version stored in NOR. > * or fix installer images for Freerunner to be built using the > workaround described in the bug report (padding the image before > passing it to mkimage) It's the easiest, and IMHO, the cleanest way to do this. > Possibly a third way to address this would be if the Freerunner can > load the bootloader from e.g. serial or SD, bypassing the flash one? > If that's the case, we could provide installer media using a recent and > corrected u-boot.

I can understand that, and indeed, upstream is not keen on accepting such a workaround. I don't have a strong opinion on a freerunner-mkimage wrapper, but it isn't needed if we fix the really specific images we need boot. So, I guess this bug should be closed, and worked around in the really specific places we need to. Regards, Thibaut Girka.
