I'm not familiar with i.MX6. If your u-boot supported loading files from sd-card ( commands fatload mmc or ext2load mmc), you can copy uImage to sd-card fat/ext2 partition and modify bootcmd via serial console in u-boot. Or you can use booting via tftp.

Hi Ivan,
Turns out that the board we use already has u-boot. Do we still need to get a working copy u-boot? I added SPECS += uboot to the etc/specs.conf file. Ran make run/demo again. I now have image.elf and uImage. What's the next step from here? Just use dd command in terminal and copy the uImage to SD card?
What other u-boot arguments need to tweaked here?

Hello Aditya,
Yes, u-boot is board specific. You need to get sources of the u-boot, configure it and build for your board. After that setup bootcmd in u-boot (you can do it over serial console or hardcode it in board config). For booting image.elf you need enable CONFIG_CMD_ELF in board config. Genode build system can make uimage automatically. Just add SPECS += uboot to etc/specs.conf

Hello,
I'm trying to run Genode on an i.MX6. And I've tried copying uImage. But that doesn't seem to be enough. I came across this : http://comments.gmane.org/gmane.os.genode.devel/813
Your set of u-boot files, is it pandaboard specific? or can the MLO, u-boot.bin be copied to any device and booted?
What's the procedure of booting from using the image.elf? (So far, i ran mkimage and created a uImage file. But that's obviously not enough. What's missing?)
Thanks and regards, Aditya
