RE: a quesion about using dsp/bios link

Kashin lin, I assume you are trying to communicate between ARM & DSP using DSPLink. You can refer to sample applications provided with the DSPLink release as a reference for how the APIs can be used. The sample applications are available within the /dsplink/gpp/src/samples and /dsplink/dsp/src/sa

Thank you Ashuari, Could you or somebody tell me how I would go about setting the virtual resolution for the frame buffer. Just looking through the davincifb.c code it doesn't seem obvious. The IOCTL commands don't seem like they can accomplish it. Is there any written documention on the davincif

RE: Suggestions on image display

Ok, I've figured out how to set the Virtual Resolution using ioctl commands and/or fbset utility. Now I'm having a hard time understanding the yres_virtual parameter. The xres_virtual parameter seems to be doing what I think it should. For example if I have an 720x480 image being displayed on the

Kashin Lin, The method doesn't really differ that much ... By using our own make system, we enable easy building on different targets, and also enable the same build system to be used for Linux-based build. However, we use the same tool-chains & DSP/BIOS. The final generated executable when you b
