HSMC debug header cyclone III dev kit

[Altera_Forum]

Hello, 

 I would like to use the HSMC debug header supplied with the Cyclone III dev kit but there is no datasheet showing its internal connections. Is there someone who know where i could find it?  Thank you

If you already have the kit you should have got a CD with documentation about this. Otherwise, go to  

http://www.altera.com/products/devkits/altera/kit-cyc3-embedded.html#documentation  At the bottom of the page you can download the reference manual which shows the HSMC pinout. The schematic, also downlandable from this page, also shows it.

I also like to use the HSMC Debug Header, especially for GPIOs. But I can't find any information about the Debug Header itself. Its easy to get the HSMC pinout on the Altera development board (in my case the DK-DEV-3C120N). But my problem is, to get the assignment from the HSMC pinout to the pinout of the breakout board (HSMC Debug Header). 

 Had I have missed some details? Or can someone help me with that?  Thanks in advance Modellpilot

A breakout-header schematic is included with 3C120 Dev. Kit, check if it's the same!

I have a DK-DEV-3C120N but I did not found any similar file or schematic. But I checked the pinout of my breakout-header according to your schematic and it looks good :)

Hi,  

I have seen the posts of FVM. I have a query about the HSMC and it would be helpful if i get some guidelines on the same.   1) Can the HSMC debug connector be used directly as an GPIO ?  2) If the above is possible then how do the map the pins on the FPGA to the HSMC debug pins ? (no relevant data regarding the CIII kit on the reference manual )  please let me know in this regard.   Sreeram

The FPGA-to-DebugHeader mapping can be seen by combining the said schematics with Dev.-Kit reference manual, that shows the mapping of HSMC extension connector to FPGA.

FvM, thanks. Your replies are really useful esp for self learning student like me. 

 Sreeram, in the Cyclone III Development Board Reference Manual, check the "Board Components: Communication Cards and Interface Ports" under HSMC, pg 2-53. It maps the schematic signal name to the Cyclone III device pin number.

Thus Bank3 cant use as GPIO on the breakout-header.  Please advice if I interpret it correctly.
