[Meego-porting] DVI display not working for Beagle xM

[Sah, Shitij SISPL]

Hi,

There was one error in my previous mail. Changed console arguments were for the image compiled from Linux omap kernel tree. There was no change done for the Meego image.

1. Following are the board details captured from the boot log

No EEPROM on expansion board
Beagle xM Rev A

Hi
Can you shaer your beagle board details?

Also hope you have compiled and created new uImage from the steps
mentioned.

setenv dvimode 800x480-16 at 60

is this resolution as per your monitor?


Thanks

Rajeev

Hi all,



I have followed the instruction as mentioned in
http://wiki.meego.com/ARM/Meego_on_Beagleboard_from_scratch . Iam not
getting any display on the Dell monitor connected via HDMI-DVI cable.



First there were no kernel messages appearing on the serial terminal. It
was as if the kernel boot hangs after uncompressing the kernel . I had
to change the kernel boot arguments

console=ttyS2,115200n8 to console=ttyO2,115200n8.



After changing, only in the serial terminal kernel messages appear but
nothing on the monitor and after kernel message Freeing init memory:292k
no update on the serial terminal



Bootscript details are



echo "Booting MeeGo Community Image"

if test "\${beaglerev}" = "xMA"; then

echo "Kernel is not ready for 1Ghz limiting to 800Mhz"

setenv mpurate 800

fi

if test "\${beaglerev}" = "xMB"; then

echo "Kernel is not ready for 1Ghz limiting to 800Mhz"

setenv mpurate 800

fi

setenv dvimode 800x480-16 at 60

setenv vram 0:2M,1:2M,2:2M

setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm
0x80300000'

setenv bootargs console=ttyO2,115200n8 root=/dev/mmcblk0p2 rootwait ro
omapfb.vram=\${vram} omapfb.mode=dvi:\${dvimode} fixrtc
mpurate=\${mpurate}

boot



Where is the problem?



Thanks,

Shitij
