SBC-S32V234 board, HDMI not working

1、Is there anyone using SBC-S32V234 board? the following attached pic 1.

2、I want to display output to displayer via HDMI, but it does not work.  Does anyone can  give some tips?

There are things I have done

first I try to enable hdmi via kernel command

[    0.000000] Kernel command line: console=ttyLF0,115200 root=/dev/mmcblk0p2 rootwait rw debug video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24

It rejects the commands

[    0.221283] fsl_dcu 40028000.dcu: Invalid video mode string 'mxcfb0:dev=hdmi'.

second, I readthe s32v234 datasheet, there is no info about HDMI.

Then,  I read the SBC-S32V.user.manuall, It gives some info about HDMI(the attached pic 2), but still not enough to let me know how can I display via HDMI.

Please try to run following command in u-boot console (before start of linux). It should solve your problem.

This configures HDMI transmitter chip connected to i2c bus 2 of S32V234.

setenv dvi_on 'i2c dev 2; i2c mw 3f 8 35'
setenv bootcmd 'run dvi_on; run loadimage; run mmcboot'
sav
boot

Please let me know if this works of not.

Thank you!

Yes ,It works. 

thanks very much .

The whole steps are as follows:

1、first download the BSP 16.1 from here.

http://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32XX-LINUXBSP01D

follow the user guide, compile the  image for s32v234sbc machine. && dd fsl-image-auto-s32v234sbc.sdcard to a SD card.

2、boot up the board, using the SD card.

3、test the HDMI output via command "cat  /dev/urandom > /dev/fb0"
