Hello, I’m using the PCI in C6455 in the design to upload the data to PC and there is one bug in me design. Here is my problem, when I watch the data I write into the memory space of PCI through the memory window of CCS3.3, I found the data is right, the pictures are as following:
The data is from 0x0001 to 0x3fff as shown above. But when I write the data to a file in PC, the problem comes, there is an extra 0x0D in front of 0x000A, 0x010A, 0x020A and 0x030A. Thus there will be 2053 bytes in the file while actually I write only 2049 bytes. You can see the data as following:
So, here is my problem, can anyone tell me how to find out where the problem comes? Can you recommend me any tools to watch the data read from the DSP through PCI?
This problem has been solved after I open the file with the command "ab+" instead of "wt+", it means to store the data in binary instead of text.
But I still want to know how to watch the data read through PCI bus, any tools can I use?
TI does not supply test equipment such as what you are asking about. I believe the term for this equipment is "bus analyzer", so you will want to search the web for companies who make equipment like what you have asked for.
