I don't understand this suggestion. How can I download the patch instead if including it
in buildroot since this patch does not exist anywhere. Theses patch are not commit in any git
right now.

Also you suggest me to include imx_usb_loader in warpoard_defconfig. I tried to
flash my uboot by using the imx usb loader from buildroot but is does not work :

[arthur warpboard_v5] sudo dfu-util -D output/images/u-boot.imx -a boot
dfu-util 0.8

I tried to update imx_usb_loader on last sha1 commit but same result.

To make it work I have to use an imx_usb_loader from github/warpboard which is different :
https://github.com/warpboard/imx_usb_loader/commits/warp/master

How can I integrate it ? Do I need to add a patch on imx_usb_loader package to use custom git ?

Thanks,
Arthur.
