Hi snakeyong,

All the information you need to program your own XTAG2 should be on this page:

https://github.com/xcore/proj_xtag2/tree/master/doc

Let us know if anything isn't clear in the instructions.

The JTAG connections are brought out with space to put a header on the bottom edge of the board, you should be able to find these in the schematic. You will however need another XTAG-2 to program your blank device. The XTAG-2 is manufactured with a chip pre-programmed with the bootloader and so avoids this step. If you need the latest bootloader firmware I recommend submitting a support request via the XMOS support ticket system on xmos.com and we can provide it to you.
