hello Is there any example of how to add JTAG port support into own non-SOPC builder design like I can directly access SPI config port? For example I want to read/set own register word from an own JTAG tool. thx rick

But still unclear now what those JTAG IR exactly do: 0000001100 0000001101 0000001110 Any more documentation about this? Or is this some high-security risk NDA stuff? thx rick

Used 0000001100 last night for shifting out own shift register content successfully... As the TCK/TMS/TDI signals are also available in the module... probably this would mean I could also use unused IR codes with own TAP controller? Now have to wait for EBV Finland returning my other NIOS board for signal capturing (o; greets rick

Great for boundary scan flashing and testing since you can add your own ir/dr definitions and get/set/reset individual boundary scan registers.> > the 0x0E is defenetly "the" USER instruction it should be 'Open' when device > is unconfigured..Hmm..might be NIOS2 config gets switched back residing in SPI during discovery (o;> > the JTAG pins are not all directly accessible so you can not add your own > Instructions > but on the Altera you can monitor full traffic on the JTAG that passes by > (that is not available on Xilinx at least pre V4)How about Lattice? rick
