On the 9s12 there was a dedicated pin for downloading firmware but on the MCX-N there seem to be a multitude of ways to program the device.&nbsp;</P><P>We will be using an external interface either one from PE Micro (which we use for the 9S12) or the MCU-Link. Should I bring out the UART pins of the MCX-N to connect to the external debugger? Will this also provide the debug function as well as firmware download?</P><P>I will be using the 100 pin LQFP part and don't want to dedicate more then a couple pins for programming / debug.</P><P>Any suggestions / diagrams would be appreciated.</P> Mon, 14 Oct 2024 12:57:05 GMT https://community.nxp.com/t5/MCX-Microcontrollers/MCX-N5x-Programming-Connections/m-p/1973361#M1773 Sagetech 2024-10-14T12:57:05Z https://community.nxp.com/t5/MCX-Microcontrollers/MCX-N5x-Programming-Connections/m-p/1974492#M1779 <P>Hello, my name is Pavel, and I will be supporting your case, I reviewed your questions, and <SPAN data-teams="true"><SPAN class="ui-provider a b c d e f g h i j k l m n o p q r s t u v w x y z ab ac ae af ag ah ai aj ak">I believe you might have a confusion with the ISP and the SWD.
