hi all,
I am trying to debug a custom board using KDS 3.0.0 and a segger j-Link ultra+. The board have a Kinetis mk20dn512 device connected in a jtag chain with altera device.
I don't have an hardware problem since I can use PE-Micro debugger in this configuration, and I also can use the segger debugger on this board if I am using the IDE from IAR.
The problem is when I am trying to open the debugger I am getting the following error log
SEGGER J-Link GDB Server V5.10c Command Line Version

Connecting to target...ERROR: Bad JTAG communication: Write to IR: Expected 0x1, got 0x5 (TAP Command : 10) @ Off 0xF.
ERROR: Could not connect to target.
Target connection failed. GDBServer will be closed...Restoring target state and closing J-Link connection...
Shutting down...
I tried adding the option -jtagconf 0,0 since the kinetis device is the closer to the TDO pin on my board, but I've got the same error
Please advise,
Best regards,
Zohar
