Trying to use the following to create the uboot acceptable image file for imx6ull:

hello_bare not linux, but baremetal or freeRTOS image

mkimage -n 'hello' -A arm -C none -a 0x80000000 -e 0x80002040 -O invalid -T kernel -d hello_bare u0

No idea - O and -T to choose which option. Available options are:

When I use -T imximage, error from mkimage:

- Can't open DCD file

Hi Joan Xie,

Thanks for your info.

I will try standalone again. Tried before, and if I did not miss anything, I remember if standalone app completes then the Uboot may get control again. This does not sounds what we want: we want the Uboot disappear after loading our app (barebone/freeRTOS) , isn't it?

Hi Guys,

Eventually I turned to barebox which looks like easier to use for some point of view.

Thank you!
