hi ,guys

I keeping geting this error when I run my program on bf537

Data access misaligned address violation

- Attempted misaligned data memory or data cache access.

the program where it crushed:

while(n<40){

getImage(buffer,width,height);----function get a char buffer

grad(gra,buffer,width,height);---calculate gra based on buffer

sumvalue_small(gra,width,height,&number);----calculate number;

printf("number is %d\n",n); ---printf out loop number;

-----crushed here when n=39;

sprintf(str, "%f", number);

fprintf(pFile,"%d %s\n",n+1,str);

n++;

}

fclose(pFile);

Does anyone know what might happened?

Thanks

Pengcheng

You should be able to track down exactly what line of source is causing the problem.
