In-System Source and Probes Usage

You can use it for any purpose that fits your application. I've used it (together with In-System Memory Editor) for calibration and test. Unfortunately, there's no documented API in the Altera JTAG stack for Source&Probe and other virtual JTAG functions. So Source&Probe capabilities practically depend on the effort your willing to spend to understand the interface.

Can you guide me how i can use it to program the external memory. Do u have any idea?

In my application, I have a Source&Probe parallel interface (address, data, r/w and manual override of regular function) to the respective components in the production design. But it's an FPGA, where a few ten multplexers and registers don't count. I see a problem with short resources in EPM240.

Thanks,

Which document? There are BSDL files for any JTAG capable device, also for MAX II.

sorry for late reply. I was out of station. Please find the attachment in which it shows that the MAX II does not support boundary scan JTAG.

You may want to refer to the recent Altera documents rather than an Application Note that was apparently written before MAX II production start. The said document also don't mention Cylone II, Cyclone III etc. Do you conclude, they have no boundary scan function.

Thanks for info. I will check out the link. Thanks.

Hi all,
