Thanks Lucas. So, if I have a board which has only eMMC (no SD card). What would be your recommendation about programming it with Barebox? Currently, I program U-Boot via uuu utility and then from Kernel, I program Barebox on boot1 partition of eMMC (boot0 is not possible). I am trying at least to program Barebox in U-boot via ums, mmc write , ... but until now I am not successful. Do you have any experience or idea? (I had forgotten to reply-all and Barebox mailing list was not on my previous Email, so I send the Email again) Best, Reyhaneh On 12/12/19 11:24 AM, Lucas Stach wrote: > Hi Reyhaneh, > > On Do, 2019-12-12 at 10:13 +0000, Yazdani, Reyhaneh wrote: >> Hello everyone, >> >> I am trying to load Barebox to the imx8mm board via imx-usb-loader, but it stops >> in the middle.
