For Richard's declarations I get .data .global _inited .align 1 Wed, 28 Oct 2009 10:17:11 GMT richardmms http://tech.groups.yahoo.com/group/trimedia/message/11821 http://tech.groups.yahoo.com/group/trimedia/message/11821 The formatting seemed to be lost last time I sent this message - so I'll try sending it again...

But this is bit confusing. ... True. ... This is where I'm seeing problem. My 6MByte arrayis not initialized & is size is not reflected Wed, 28 Oct 2009 09:18:07 GMT Mahesh http://tech.groups.yahoo.com/group/trimedia/message/11818 http://tech.groups.yahoo.com/group/trimedia/message/11818 Hello, Thanks for your responses, but I still have some doubts. ... But how can I initialize an array of 6 Mbytes. I tried that using static array_name[6MB]; Wed, 28 Oct 2009 08:40:08 GMT harm_verhagen http://tech.groups.yahoo.com/group/trimedia/message/11817 http://tech.groups.yahoo.com/group/trimedia/message/11817 ... should be int temp[10]; // .bss are all zeros too. zero bytes Wed, 28 Oct 2009 08:37:39 GMT harm_verhagen http://tech.groups.yahoo.com/group/trimedia/message/11816 http://tech.groups.yahoo.com/group/trimedia/message/11816 initialized data ends up in your .data segment uninitialized data ens up in you .bss segment. .data segment ends up taking space in your image. .bss does not Tue, 27 Oct 2009 17:51:13 GMT Chuck Peplinski http://tech.groups.yahoo.com/group/trimedia/message/11815 http://tech.groups.yahoo.com/group/trimedia/message/11815 I think Alfred is right. Why not figure out how much memory is used by seeing how much is available on the heap after the program starts? Call malloc with Tue, 27 Oct 2009 16:44:08 GMT Alfred Lee http://tech.groups.yahoo.com/group/trimedia/message/11814 http://tech.groups.yahoo.com/group/trimedia/message/11814 I would make a guess that the compiler is smart and knows about the declaration without initialization and took a shortcut to save the address and size and Tue, 27 Oct 2009 15:38:38 GMT Mahesh http://tech.groups.yahoo.com/group/trimedia/message/11813 http://tech.groups.yahoo.com/group/trimedia/message/11813 An array of size 6 Mbytes is gloabally declared in a C file (of course not initialized) & used also. If I run tmsize on .o of this file it doesn't show that Fri, 23 Oct 2009 14:27:44 GMT Chuck Peplinski http://tech.groups.yahoo.com/group/trimedia/message/11812 http://tech.groups.yahoo.com/group/trimedia/message/11812 The CTF file is in fact an instruction trace. If you can identify where the 5th and 7th frames start and end, you can edit that file. How about if you edit Fri, 23 Oct 2009 05:45:15 GMT Mahesh http://tech.groups.yahoo.com/group/trimedia/message/11811 http://tech.groups.yahoo.com/group/trimedia/message/11811 Hi, I was looking for some help on tmact usage. Is it possible to generate data for particular frame from ctf file using tmact -r option. Like, I've ctf file Wed, 30 Sep 2009 22:16:23 GMT Chuck Peplinski http://tech.groups.yahoo.com/group/trimedia/message/11810 http://tech.groups.yahoo.com/group/trimedia/message/11810 My suggestion is to contact your local NXP sales rep and ask him or her what it takes to get started on the newer PNX1005.
