Hi everybody, I'm working with 6711 dsk and CCS2. I'm trying to profile my code with DSP/BIOS statistics accumulators. In my program I handle file I/O with probe points. For some unknown reason, that doesn't seem to work (the cpu repeatedly crashes). Has any of you experienced this? Any clue? Is it possible to hand file i/o with DSP/BIOS? Can you give me same simple source code to do this, or a reference I could look at? TIA Federica Legger |

Hi Federica, I believe you should try using rtdx instead of probe points for file io. Probe points require the cpu to halt every time the file io transfer takes place, which may be affecting your program. There is some examples using rtdx for reading and writing to files in the ti\tutorials\dsk6711\hostio1 & 2 directories. The text for the tutorial can be found by going Help->Tutorials in CCS. And selecting Using DSP/BIOS->Getting Started with DSP/Bios-> Connecting to Virtual I/O Devices in the Help Window. Hope that helps. -Ron -----Original Message----- From: fedelegger [mailto:] Sent: Wednesday, March 20, 2002 4:02 AM To: Subject: [c6x] using files with DSP/BIOS Hi everybody, I'm working with 6711 dsk and CCS2.
