Re: [beagleboard] ULCD7 Not working on Ubuntu
Hi again, Just let you know about a quick solution on this issue. Try to use request_irq() instead of request_threaded_irq(), this solves the issue and you will get the irq function called when press the screen. However, you need to modify the remaining part of driver file to handle press sequences in a proper way. Regards, Ozgur.

Re: [beagleboard] ITU-R BT 656 compatible camera interface
Hi there, I just would like to share my experience on enabling BT.656 support in BBxM where Kernel 3.7.13 (stable-kernel) is in use. The changes made were inside of omap3isp and board-omap3beagle. Basically bridge and bt656 parameters were missing. The parallel bridge needs to be disable to collect YCbCr8 input data. In order to do these configuration in ccdc_config_sync_if() and ccdc_configure() functions, you can check out the latest version of ispccdc.c in TI Kernel distribution.

Re: [beagleboard] Ubuntu SGX Install issue
Hi, I have BB-xM and just want to check SGX acceleration.

However, when I run test scripts in /usr/bin/armhf/es5.0 in BB-xM, I am getting an error says error while loading shared libraries: /usr/lib/libsrv_um.so: file too short. Then, I have realized that there is no .ko (bufferclass_ti, omaplfb, pvrsrvkm) and also libsrv_um.so file size is 0 in the filesystem in BBxM. What did I wrong? Any help would be greatly appreciated.
