Hi,

If you are downloading any application, please on the program button from the Quick Panel options. 

If you are trying to use the debugger, then, please click on the Attach_Jlink or Attach_Kitprog3_Miniprog4. Please check the below document for more details for source code level debugging.

Thanks,

Thanks for your reply.

Problem is about disconnecting serial port when i try  to download application at ModusToolbox

Error message is "Serial port not detected... & Download failed"

I don't know why it is caused bacause it was not problem until last week.

Of course i checked documentations regarding set-up to solve problems but it was failed.

Hello Dheeraj.PK,

I have the same issue with my CYW920721M2EVK-02.  The board programmed without issues.  Seeing these log messages after launching "[code example name] Attach_KitProg3_MiniProg4"
