Hi, I'm having some problems with a mixer sw component. Debugged for a while a started to doubt whether maybe hw might be the cause. I found one interesting...
Hi Harm. Logging this as a TCSHelp issue (rather than TMUG) will increase the chance that someone at NXP takes time to investigate. Logging here means that...
... function ... Thats exactly what I also thought. Its like those cache operations before/after painting the border are not happening. it seems those cache...
... Which is exactly what was happening. I found that tmdlMbs2 sometimes reports a done callback _before_ the corresponding task is actually finished. ...
I use usb over PCI in tm1500, and all hardware detect go corrent, but the pci int have some trouble. I use the INTA, and int the interrupt handler, it says: ...
I use shared memory to transfer video from Host PC to Trimedia board accross PCI bus. I find that: Data write to shared memory will significantly increase CPU...
Is the CPU load increase on PC side or DSP side? Assuming DSP side, is it overall increase or increase in time spent reading the just written data? I believe...
May be we use different terms? There is cache copyback. After this instruction completes, dirty cache is forced written to memory. And then there is cache...
PC CPU load increased. Sharedmemory return a Pointer which is considered as a normal memory pointer. but write to this region result longer time than a normal ...
Perhaps I have not express what I mean. The problem is:when use rmb, all read request should be done, and when use wmb, all write request shoud be done, the...
Yeah, I think a cache copyback of all data that need to be copyback and a cache invalidate of all data that need to be invalidate should work, but I have not...
um, your while loop is only over the print statement. You only read one character? If that's not it, are you running this on a PCI hosted system? Does ...
This may be closer to what you intended? i = getc(image); while (i != EOF) tmDbg_Print (DBG_ROOT, DBG_ALL_FLAGS, "%c", i); i = getc(image); } Best Regards, ...
Test show: Windows XP is affected. windows 2003 may too. But Windows 2000 pro is OK, it seems windows 2000 shared memory no difference with normal memory. I'am...
I have test dynboot on tm1500, I change _TMLINKTYPE to dynamic in tmdbg_jtag1500.bat, it seems ok, but when I download the image to the board, it crashed. ... ...
I found the answer: this overhead is used for containing a part of administration for the particular memory block. And size of this extra block of memory...
I assume it doesn't cause any problem. You are simply getting more memory than you requested. So it is not a problem. I don't know the actual reason for...
Following the poll on whether to participate in the Mississippi State University eGroup survey, we decided to do so. The survey, if you want to do it, is at: ...
... The overhead is the biggest in the MpCached type memspace. (the shared memspace). The reason is that both the actual user buffer _and_ the administration...
I use sharedmemory to transfer video data from PC to PNX board. It run OK on Core2Duo platform running windows 2000 pro/server. But it will crash after 1 - 12...
Of course, any memory allocation will have some overhead. malloc()/free() will have the lowest overhead. It has the corresponding drawback of lack of control...
If I have to guess, it's the SMP that's the trouble. The ISR must be written much more carefully with proper spinlocks to work correctly on SMP machines....
Absolutely speaking, the lowest overhead is to allocate a large chunk of memory and manage yourself. You can take advantage of how you use your memory to save...
How can I download my application program to nor flash using pci bus without using jtag? Hardware reference information as follows: 1¡¢Main processor is...
Very simply put, you first have to be able to access the Flash, e.g. run a Flash format test. If that works, you simply modify the exProductionBurn target...
