Re: [U-Boot] android fastboot support on U-boot
Resend, forgot to copy the list.

Hi shulin,
Now I working on porting android fastboot protocol to U-boot,does somebody add fastboot protocol patches to U-boot?
Can yopu please tell me what the "the android fastboot" protocol is?

"Fastboot is protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images."
I was already wondering how feasible it would be to have a board with USB slave behave like an USB memory stick to flash the firmware by simply copying a file from the host to it.

Yet another alternative for the problem already solved by DFU[1]? Damn, after some recent activity in this area again I was starting to raise my hopes that more people realize such a thing exists already :(
Thanks Detlev

OK, there appears to be U-boot support as well. It needs a util on the host, but for development purposes that would be fine.
A usb-storage like solution would be more flexible. It could have the option to poke around in a jffs2 image while still in u-boot. Very nice when the firmware doesn't boot or let you log in due to a small mistake in the image.
But I guess that jffs2 R/W support in U-Boot is a bridge or two to far :-))

Is that fastboot usb-storage based? From the wiki-page that you referenced I only see that you also need a separate host tool to use it. So that's not much of a difference, is it?

And maybe a bridge I would not invest time anymore as UBI+UBIFS seems to be the weapon of choice against the fallability of NAND devices.

No, the usb-storage based thing was something I had in mind as a solution for easy firmware update and manipulation.
The omapzoom project has a u-boot with fastboot support.

Beware, that the u-boot base rev is very old.
