Hello, I am using an i.mx6 sabresd, on which I have to manually activate the HDMI. To do so, I use the following command on u-boot prompt :
=>setenv mmcargs 'setenv bootargs console=ttymxc0,115200 root=/dev/mmcblk2p2 rootwait rw video=mxcfb0:dev=hdmi, 1920x1080M@60, if=RGB24' The trick is that I have to unplug the HDMi before the kernel starts, and plug it after, but this is not the point. I'd like to automatize this by using a boot.scr (to help deployment on other i.mx). Si I have created a boot.txt : setenv mmcargs 'setenv bootargs console=ttymxc0,115200 root=/dev/mmcblk2p2 rootwait rw video=mxcfb0:dev=hdmi, 1920x1080M@60, if=RGB24' boot And I create the boot.scr using mkimage -A arm -T script -O linux -d boot.txt boot.scr. But, when booting, it makes a loop (boot make uboot reload the configuration, where it reads boot so it begin again). Without boot... no boot. I've tried a lot of possibilities : boot 0x120000000, bootm, bootz, with a lot of options, nothing works. What am I doing wrong ?
