I have started with building kernel 2.6.37 (without applying any patches) since I always used precompiled image of this kernel (Android). I used omap2plus_defconfig from stable kernel tree of 2.6.37 as config file during this build. As of now, usb interface and ethernet is not up at normal conditions - this could be due to config file. Also, I need to get login command prompt on serial port - this could be some issue with getty command in /etc/init/ttyO2.conf. I will get debug logs after this. I will keep posting as there is any progress in this.
Do I need to apply any patches for beagle board to this kernel to get this working?
