To change the amount of memory from 256 MiB to 128 MiB you must have the jpeg demo codec server sources. If you only have the x64p file you won't be able to work with 128 MiB. Once you can rebuild the x64p file from sources you will need to make changes to the TCF file to change the memory map. You need to recompile dsplink - changes need to be made to CFG_Davinci.TXT. You need to load the cmem driver, and dsplink file with different parameters. You will have to change the "mem=120M" to something else, like "mem=56M", or "mem=90M" depending on how much DSP memory is needed, in order to limit the ARM's use of memory and leave the rest for the CMEM, DSP, and DSPLINK. There is no need to change the ARM application.

But my devboard only has 128M ddr, I need to rebuild the server. Does anyone know how to config the sever tcf and cfg file for this demo? regards gli _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
