Part Number:TDA2EXEVM
Tool/software: Linux
Dear Sirs:
When using VSDK 03_03_00_00, I found there is no Linux video frame buffer inside it. And even when we enable the frame buffer inside the DRM the system is still no frame buffer. After we use the dra71-evm.dtb and set DISPLAY_ON_A15_LINUX from 0 to 1 in omapdrm/oma_drv.c , the VSDK can see the frame buffer device(/dev/fb0) in the Linux and it can use frame buffer to display. This is the way PSDK Linux Automotive used.
However, if using in this way, it will cause the VSDK assertion or the kernel crash in interrupt if we start the VSDK demo case later.
Just want to know: How we can use both VSDK and Linux frame buffer device to draw the GUI without any assertion or crash. Can you point me a way to do it?
