Driver built without XOrg support. And Qt libs are built with -no-xcb option, so it's not about XOrg. I don't know how Qt draws windows without any OS window system, but Qt 4.8 works great with QApplication::GuiServer option and draws windows by itselves. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Creating The SGX Driver For Ubuntu 14.04
Not shure if it's better to create new theme.. I'm trying to build sgx drivers for 3.8 kernel. I know that there is a lot of disccusions here about that, but I can't find any exact information here. What I have: BeagleBone Black + element14 LCD7 cape RobertCNelson bb-kernel kernel, branch remotes/origin/am33x-v3.8.13.x + patch to create (un)register_vsync_cb functions for SGX code to compile. Graphics SDK 5.01.01.01 from TI. Everything compiles good. But on insmod pvrsrvkm.ko I got this: http://paste.org/73324 (Lines started by MVC: are added by me for debug reasons) 1. If I understand correctly, pvrsrvkm crashed on line 575 here: https://github.com/RobertCNelson/ti-sdk-pvr/blob/5.01.01.01/Graphics_SDK/GFX_Linux_KM/services4/system/ti335x/sysutils_linux.c#L575 when trying to map memory from TIMER7 region. devmem2 0x4804A054 (SYS_TI335x_GP7TIMER_TSICR_SYS_PHYS_BASE = 0x4804A054) gives bus error and abort on non-linefetch. Am I right thinking that sgx driver wants to use timer7, but it's disabled? 2. Exactly same scheme works good with 3.2 kernel from element14 and same GFX SDK, modules load good, demos from /usr/bin/SGX work good. But timer7 is disabled too and devmem2 on it gives exactly same error.

Re: [beagleboard] Re: BB-View cape problem
After 5-7 reconnections of BB-View in expansion slot it looks better, but not 100% ok. I think, the problem is that expansion connectors on BBB and on BB-View has bad electrical contact.
