dm6446 vs omap3530
hi,everyone: I see that dm6446 contains a 300Mhz ARM and a C64x+ DSP, while omap3530 contains a 600Mhz ARM and a C64x+ DSP. Dm6446's DSP is a little stronger than omap 3530. DM6446 is much expensive than omap 3530, is it right? But I think omap3530 is better than dm6446. Could someone give me a explanation why dm6446 is better? -- Thanks, Zhenfeng Ren ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
Re: when port a software , bus error
hi, Thanks for your answers. Now, I have changed the member variable in struct to make sure that the alignment is correct. -- Thanks, Zhenfeng Ren ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
when port a software , bus error
hi, everyone:
Just like the code as below:
1 #include algorithm
2 #include stdio.h
3
4 #pragma pack(push, 1)
5 typedef struct _test_c
6 {
7 char m;
8 int data[10];
9 }test_c;
10 #pragma pack(pop)
11
12 int main()
13 {
14 printf( sizeof test_c is %d \n, sizeof(test_c));
15 test_c test;
16 for(int i=0; i10; i++)
17 test.data[i] = 9-i;
18 //int data[10]={9, 8, 7, 6, 5, 4, 2, 3, 1 , 0};
19 std::sort(test.data, test.data+10);
20
21 return 1;
22 }
This code can work on X86, but cause bus error runing on Davinci(My
board is DM6446, GCC 3.4) .
I know the problem is:
std::sort(test.data, test.data+10);test.data is not 4-Bytes aligned.
The software I want to port uses structs liking test_c a lot.
Could anyone give me some advice ?

How to run DMAI Based GStreamer ?
hi,everyone My EVM is DM6446 with DVSDK 1.3 downloaded form TI website. The codes I compile are from https://omapzoom.org/gf/project/gstreamer_ti Gstreamer is compiled successfully except plugin mad(libid3tag.so.0 cannot find one symbol). I try many avi files, and I failed all. The video and audio files in DVEVM 1.10 cannot be played ,too. Can anyone give me an example how to use this gstreamer ? Or is there a commom video files used for testing? -- Thanks, Zhenfeng Ren ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
