HI,
I use readwrite example to send an image from ARM side to DSP side for compression. I combined a codec with readwrite dsplink example from TI. My dsp executable file is nearly 7MB so I changed the memory map (see attached file). It appears that the application is running well until ARM side tries to load dsp executable on dsp side (PROC_Load ?) but i can't be sure

I'm using Ubuntu 10.4 and TI MAKE system to build sources using DSPLink, both for GPP and DSP
EVM : DM6467T
CCSv 4.1
DSPLink 1.64
DVSDK 3.1
C6000 7.0.1 compiler
Windows 7 pro 64 bits
Any help would be great
Thanks,
