ECG implementation on TMS320VC5505 EVM

Raghu Vishnubhotla

Hi,

I have 2 questions on ECG daughter card for VC5505.

1. J22 is a 2x11 double row male header on VC5505 EVM which is used to interface the ECG front end daughter card and VC5505 EVM. But the corresponding female on the daughter card is 2x10. I have the ECG daughter card as well as the digital stethescope daughter card. both seem to have the same problem.

2. To run the ECG DSP software in debug mode, the instruction mannual asks to copy a .gel file from the CD. But no such file is there on the CD. I've checked the myti software page as well, but the the files required for software intallation seem to be missing.

Thanks

Raghu,

#1) J22 pins 21 and 22 are to be left unconnected when ECG daughtercard is installed. Not sure why the extra pins are on the EVM, but not needed for ECG or Digital Stethoscope.

#2) I found the gel file in folder \C550X Software\Output on my machine. Have you looked in this location?

Regards.

#1) thanks.

#2) Cant find the folder on the CD. The CD shows only an exe file and the application report document.

Raghu,

I doubled checked the CD contents for the VC5505 EVM and found that the gel file is installed with the Target Content. The installation folder is usually is determined when you install the contents of the CD. For me it is located under CCS3.3 folder in \boards\evm5505_v1\gel. The other location I told you must have been from an early internal release.

Regards.

Hi ,

There seems to clash in the terminology used in the instruction mannual (http://focus.ti.com/lit/an/sprab36a/sprab36a.pdf), and the one that are actually present in the target. For example, the mannual actually says that there should be a bootimagecreation zip folder. but I wasnt able to loacate it. The only that looks close is EVM_samples @ the location \CC_studio_v3.3\evm5505_v1\demo.

Basically , this is the first time i'm programming a DSP. If you can guide me through the installation , because the information in the mannual seems to be misleading.

Thanks

Raghu
