For something like USB serial or USB ethernet I fully agree with having it written in a way we use it together with fastboot and or DFU. If I remember correctly (On vacation, to lazy to check the code) we had the setup with USB serial running. The device started u-boot up with USB serial and DFU in run-time mode offering the additional interface. You could then connect via serial to u-boot and once you triggered the switch to DFU mode with dfu-util on the host we switched to full DFU mode and USB serial was gone. In addition to that we can offer a configuration to enter the DFU directly when a button is pressed during startup or such. So in summary I agree with your idea having the possibility to enable more then one. Just having DFU and fastboot enabled together made me wondering. :) regards Stefan Schmidt _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
