This one is new and already merged into the linux kernel. This one is on my list once I have the fastboot part merged :) There should be an at91 udc driver in the uboot-usb git tree. The last time I checked, the at91 driver was in the next branch. >Any other hardware platforms that support the new style gadget >framework yet?

All drivers in u-boot are using the old style interface which is linux from the late 2.4 time frame or very early 2.6. The dwc3 for which I plan to have fastboot is a huge usb3 drd controller. Having two different codebases does not make much sense. >> The gadget implements the getvar, reboot, download and reboot commands. >> What is missing is the flash handling i.e. writting the image to media. > >You may have seen the DFU patches on this list recently.

I haven't seen it yet. From the protocol layer it is simple: You are told to receive X bytes. Once you sucked it up are told where you have to write it. The destination address is a partition name. So what I planned to do is to add the android partition format which is efi/guid based I think and then simply execute a "nand write data partition" command. If there is code that can be shared between DFU and this fastboot thingy then I'm the last person that does not want it. >regards >Stefan Schmidt Sebastian _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
