Thanks Robert, I had the Ubuntu demo image of Nitty 11.04 running on
my BB-xM Rev. C. Everything looks fine, except the cpu frequency:
ubuntu@omap:~$ sudo cat /proc/cpuinfo
Processor : ARMv7 Processor rev 2 (v7l)
processor : 0
BogoMIPS : 503.12
Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x3
CPU part : 0xc08
CPU revision : 2
Hardware : OMAP3 Beagle Board
Revision : 0020
Serial : 0000000000000000
and
ubuntu@omap:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/
cpuinfo_cur_freq
300000
ubuntu@omap:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/
cpuinfo_min_freq
300000
ubuntu@omap:~$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/
cpuinfo_max_freq
800000
Well, the omap3 is only running at 300MHz ?
So, I changed the mpurate to 1000 in the boot.cmd and updated the
booting parameters with ´. /boot/uboot/tools/update_boot_files.sh´ .
What I got from the bootlog:
[ 0.000000] Kernel command line: console=ttyO2,115200n8
console=tty0 root=/dev/mmcblk0p2 rootwait ro vram=12MB omapfb.mode=dvi:
1280x720MR-16@60 fixrtc buddy=none mpurate=1000
...
[ 0.125000] Switched to new clocking rate (Crystal/Core/MPU):
26.0/332/1000 MHz
...
But nothing really changed with the CUP frequency
Does anyone has an idea how I could change the CPU frequency? Thanks
for the hints in advance!
Best regards,
Hans
