Hi, I meet a problem when I use Jpeg library( Build ID: 2.00.002) in my project.
My code is bellow which very simple, I do it as the demo from “dm6446_jpegenc_2_00_002_production\packages\ti\sdo\codecs\jpegenc\app\Client\Test”.
－When I run this task in DSP side without DSPlink environment, the .out file is loaded via emulator from JTAG, the While-loop can run continuously.
－But When I run this task in DSP side with DSPLINK, which means boot from arm and two cores run together, the program crashed after soon. I doubted that maybe the DSPLINK configuration is incorrect on my project. Then I used the dsplink demo from “dsplink_1_30_08_02\packages\dsplink\dsp\src\samples\scale”. I add my code in the function “static Int tskScale()” , before the DSPLINK related code” status2 = TSKSCALE_create (&info);”. It crashed as well. Of course, I have checked the stack size and heap size, and enlarge it if it’s too small. Besides, I know the program crashed in "IIMGENC1fxns->process" by invoking the “abort()” function.
