I use the ttyACM0 ( COM3 port in my PC) to enable MAVLink and ttyS2( TELEM2 in PX4 and COM4 in my PC) for the external mode. The Following image is my model configuration setup :
I was able to build the firmware successfully. However, when I run the external mode, it got a error and said the following ( compied from diagnostic windows) :
Program: [================== ] 90.6%
Program: [=================== ] 97.0%
Program: [====================] 100.0%
Verify : [ ] 1.0%
Verify : [====================] 100.0%
Rebooting.

Have you checked the baud rate? Make sure that it is in line with the external mode baud rate (921600).

Hello Mahanti,
I encountered this issue with Pixhawk 2.1 Cube. Can you resolve this problem ?

I had same problem, and this is how I solved it.
In my case, I created new empty folder, and then in MATLAB I moved my Current Folder to that new empty folder.
Then it worked.
