Hi everyone,

I'd like to know if something is going on regarding this topic ?

I managed to flash a yocto BSP with SPL with USB+serial with Fabio help,
but I found it a bit painful, and hard to automate.

- Go into serial console to reboot, interrupt uboot, and type bmode usb.
- Quit serial console
- Launch imx_usb_loader,
- Send u-boot.bin with ymodem (teraterm on windows, kermit on linux)
- Go back to serial console, interrupt u-boot
- Mount Usb OTG (ums 1 mmc 0)
- Flash wic.gz image
- Reset u-boot.

What is a bit annoying is the use of ymodem to load u-boot.bin.
Anybody has a cleaner solution ?

Thanks
