Debugging 4 nios II cores

[Altera_Forum]

Hi , 

 I have made a system with 4 NIOS II cores each with its level 1 jtag. One core is connected to the JTAG UART.  My understanding according to the documentation is that i can debug multiple NIOS cores at the same time using the NIOS II SBT. I have previously done so for 2 NIOS cores.   But in the 4 NIOS core case when i try debug the software project for the 3-rd core i still only get 2 valid debug targets.( which is for core -1 and 2 )  Since i have 4 nios cores shouldn't i get 4 targets to choose from in the debug configuration.  I am using Quatrus II 9.1 with sp2 web edition and NIOS EDS 9.1 . Any help would be appreciated   p.s Just wondering if i am correct in assuming that adding JTAG UARTs would not be necessary to add valid debug targets

Hi All, 

 I have attached screenshots of the sopc system and the targets shown in the Nios EDS. As can be seen i only get 2 targets to attach to rather than the expected 4 targets for the 4 CPU's..  I have checked this in a Quatrus II 10 subscription edition as well ( same problem ) so it seems to be an issue with the system i have built.  Any help would be appreciated

Hi, i also meet problem in multi-core debugging, have you solved it?
