[maemo-developers] Maemo5 on Beagle

Tue Oct 27 16:03:16 EET 2009

Hi all,

I have uploaded my kernel at  
http://gitorious.org/maemo5-sgx-beagle/maemo5-beagle-cvm . It is  
omap-pm kernel with beagleboard patch on top, as well as few patches  
to get Nokia SGX module going. Defconfig is at  
http://rcn-ee.homeip.net:81/dl/omap/beagle/v2.6.29-e63cf07-pm42.1/defconfig  
(answer 'm' to the PVR module when doing make oldconfig)

A compiled kernel can be found at  
http://www.daimi.au.dk/~cvm/repo/beaglepmsgx2.tar.gz. You will need to  
follow instructions on  
http://www.omappedia.org/wiki/Maemo_Getting_Started. When that is  
done, copy in http://www.daimi.au.dk/~cvm/sgx into /etc/event.d on the  
filesystem.

Current status we have is that it boots Xorg just fine, hildon-desktop  
starts, except it seems to insist on outputting on LCD interface and  
leave DVI and S-video blank. Anyone who can check if it actually shows  
something on that interface?

Debug tip: Observe your console log saying SGX 5, it means SGX  
succeeded in initializing.

Pitfall:  omap_pm_set_min_mpu_freq(&sgx_dev, vdd1); is commented out  
in drivers/gpu/pvr/services4/system/omap3430/sysutils_linux.c. If  
anyone knows of any patches that contain the MPU stuff, it would be  
much welcome.

Regards,
Carsten Valdemar Munk
