no output of gingerbread on beagle-xm

Parimal Naigaonkar

Hi,

I have gingerbread working on beagleboard-xm now and i have connected one lcd+touch screen through hdmi-hdmi cable as this lcd does'nt have dvi port on it.

I am not able to get any output on this screen.

I am using this script for making boot.scr;

#!/bin/sh

cat <<EOF > boot.cmd

if fatload mmc 0 80200000 uImage

then

echo ***** Kernel: /dev/mmcblk0p1/uImage *****

echo ***** RootFS: /dev/mmcblk0p2 *****

setenv bootargs 'console=ttyS2,115200n8 androidboot.console=ttyS2 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off mpurate=1000 omap_vout.vid1_static_vrfb_alloc=y vram=16M omapfb.vram=0:8M,1:4M,2:4M omapfb.mode=dvi:640x480MR-16 omapdss.def_disp=dvi'

bootm 0x80200000

EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute uImage.bin' -d boot.cmd boot.scr

i have gingerbread-dsp running on beagle-xm

now i am able to get output but it takes 15 mins to show home screen , till then it shows android logo

and after home screen comes it is very slow. actually nothing works.

How do i improve performance

my boot args are

#!/bin/sh

cat <<EOF > boot.cmd

if fatload mmc 0 80200000 uImage

then

echo ***** Kernel: /dev/mmcblk0p1/uImage *****

echo ***** RootFS: /dev/mmcblk0p2 *****

bootm 0x80200000

EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute uImage.bin' -d boot.cmd boot.scr

Since you say "gingerbread-dsp", you installed the prebuilt TI DVSDK package w/ Gingerbread?

Maybe try this variation I found on the TI-android userguide:
setenv bootargs init=/init console=ttyS0,115200n8 ip=dhcp rw root=/dev/mmcblk0p2 rw init=/init rootwait mem=256M androidboot.console=ttyS0 omapfb.mode=dvi:1024x768MR-16 omapdss.def_disp="dvi" (Change to your resolution)

Or:

You may try looking for answers on the IRC:

Hope this helps.
