I am trying to write to multiple microcontrollers at the same time with MWU16 using a USB hub.In the case of simultaneous writing to multiple microcontrollers, is there a way to know which microcontroller became NG when any one of the writes became NG?
The fact that the writing was NG is displayed as an error in the Status of the Connection List field of MWU16. If you double-click the line that displays ERROR, the green LED on the corresponding on-chip emulator will blink for 5 seconds. It is the microcontroller to which the on-chip emulator is connected is NG. See "3.210 Connection List Fields" in the MWU16 User's Manual.
