I am able to connect to my Speedgoat target machine after target reeboot. But after running it for 10 min or more, connection is lost. I am using Matlab R2019b and Simulink Real-Time Version 6.11 (R2019b).
Here is the response from slrttest (after target has been running for a while).
### Simulink Real-Time Test Suite
### Host-Target interface is: TcpIp
### Test 1, Ping target computer 'TargetPC1' using system ping: ... OK
### Test 2, Ping target computer 'TargetPC1' using SLRTPINGTARGET: ... OK
### Test 3, Software reboot the target computer 'TargetPC1': Error using slrttest (line 160)
TargetPC1: Port is not open

Hi Mats,
Could you make sure that no other host PC or MATLAB release is trying to connect to the target? Are you using a direct connection, or do your target and host PC communicate via a LAN?

Hi Dimitri,
Ping reset brings my connection back. Thank you very much!
