I have a Freescale sabre, for which I have generate
core-image-x11 with yocto. Booting and using it with serial port is ok, but I can't use the HDMI display. The HDMI is detected by u-boot (I an see two tux on the hdmi display), but not after. Here are some informations given by u-boot :
U-Boot 2014.10+fslc+g5fd0b60 (Feb 27 2015 - 11:26:20)
CPU: Freescale i.MX6Q rev1.2 at 792 MHz Reset cause: POR Board: MX6-SabreSD I2C: ready DRAM: 1 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2 auto-detected panel HDMI Display: HDMI (1024x768) In: serial Out: serial Err: serial PMIC: PFUZE100 ID=0x10 Net: FEC [PRIME]
I have tried this in u-boot :
setenv mmcargs 'setenv bootargs console=ttymxc0,115200 root=/dev/mmcblk0p2 rootwait rw video=mxcfb0'
But it doesn't change anything, even if the modification can be seen in
/proc/cmdline after the booting ; and
setenv mmcargs 'setenv bootargs console=ttymxc0,115200 root=/dev/mmcblk0p2 rootwait rw video=mxcfb0:dev=hdmi'
makes the booting stopping at
Does anyone know how to support hdmi ?
