The original boot arg in u-boot was:
mmcargs=setenv bootargs console=${console} ${optargs} mpurate=${mpurate}
buddy=${buddy} camera=${camera} vram=${vram} omapfb.video_mode=${dvimode}
omapdss.def_disp=${defaultdisplay} root=${mmcroot} rootfstype=${mmcrootfstype}
with dvimode=640x480MR-16@60
I changed the mmcargs to
mmcargs=setenv bootargs console=${console} ${optargs} mpurate=${mpurate}
buddy=${buddy} camera=${camera} vram=${vram} omapfb.video_mode=1024x768MR-16@60
root=${mmcroot} rootfstype=${mmcrootfstype}
After booting the beagle into linux I get:
beagleboard:~# dmesg | grep PVR
[ 84.306304] PVRSRV_PIXEL_FORMAT_ARGB8888
beagleboard:~# cat /proc/cmdline
omapfb.video_mode=1024x768MR-16@60 root=/dev/mmcblk0p2 rw rootfstype=ext3
rootwait
It's still the wrong pixel format. I also tries 800x600MR-16@60, and
640x480MR-16@60. Always the same pixel format.

Sorry, of course the /dev/pvrsrvXXX is successfully opend before, as you can
see here:
...
open("/dev/pvrsrvkm", O_RDWR) = 3
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
ioctl(3, 0xc01c670c, 0xbe9639ec) = 0
ioctl(3, 0xc01c6700, 0xbe9638c4) = -1 EFAULT (Bad address)
fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(4, 66), ...}) = 0
ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, {B115200 opost isig icanon echo ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x40021000
write(1, "PowerVR device not found\n", 25PowerVR device not found
) = 25
exit_group(0)
The file exists:
beagleboard:~# ls -l /dev/pvrsrvkm
crw-rw-rw- 1 root root 249, 0 Feb 14 18:10 /dev/pvrsrvkm
and the modules are loaded without a error message in dmesg.
Thanks,
Frank
