Dear Community,

Please find the reproduction steps (i.MX6Q):

Power cycle the board
Stop at U-Boot prompt


./JLinkGDBServerExe -select IP=192.168.2.72 -device MCIMX6Q6 -endian little -if JTAG -speed auto -noir -noLocalhostOnly

(gdb) target remote localhost:2331
(gdb) hb *0x17800000
(gdb) c


Boot Linux


GDB halts on the address:
Breakpoint 1, 0x17800000 in ?? ()


At this point I do want to start the other instance of GDB Server (for Core #1):

./JLinkGDBServerExe -select IP=192.168.2.72 -device MCIMX6Q6 -endian little -if JTAG -speed auto -noir -noLocalhostOnly -scriptfile ~/work/J-Link-PRO/MCIMX6-core-1.JLinkScript -port 2334 -swoport 2335 -telnetport 2336 -logtofile -log ~/aaa.txt


Unfortunately, it is not possible (after following the above steps) to start
multiple GDB server instances to use Ethernet as the connection medium.


However, I can start multiple instances with '-select USB' switch passed (instead
of -select IP=).


Is the connection to multiple GDB Servers supported with ETH (IP=192.168.2.X) or
is it only working via USB (J-Link PRO has both USB and ETH ports)?


Please find attached aaa.txt log file.



Note:
The MCIMX6-core-1.JLinkScript is from
linode.boundarydevices.com/jlink/MCIMX6-core-1.JLinkScript


With the above setup (debug steps) the guidelines/scripts from
wiki.segger.com/I.MX6DQ
are not working.


Thanks in advance for your help.
