I just download a project:
https://github.com/xcore/sc_jtag
But when I build the project in xTimeComposer, I got error:
Error: Undefined reference to 'jtag_pin_TCK'
Error: Undefined reference to 'jtag_pin_TMS'
Error: Undefined reference to 'jtag_pin_TDI'
Error: Undefined reference to 'jtag_pin_TDO'
Where are those pins defined? Thanks!
(I want to do boundary scan, and read this post:
https://www.xcore.com/forum/viewtopic.php?f=26&t=1704
and find the project above!)
problem with project "sc_jtag": undefined JTAG pins?

If you cannot locate them in any of the source files, they may be defined in the XN file.

This project does not have a declaration for the jtag ports/pins at all. (There is a todo line somewhere).
But there are only extern declarations for the ports. So, you can specify the ports manually.
I guess this project does similar things than the xtag2 boards do. So, this jtag pins are gpio pins from the code point of view.

Yes, I found those pins from XTAG2 schematic: add the port definitions manually, and compile successfully.
So far, the program runs(I connects XTAG2 to sliceKit board), but get number of taps: 0, (which is wrong, should be 1)
Just curious: when somebody developed the codes, haven't they tried to compile and do the basic debugging and testing?
