I have tried to program the MCU using Flash Magic tool, but it was not working and showing Failed to autobaud error. I also tried to program the MCU using JP3 UART pin and the result is the same (not sure this way is correct or not).</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="nxp error.PNG" style="width: 673px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/243450iAE260C6912CDD2F5/image-dimensions/673x99?v=v2" width="673" height="99" role="button" title="nxp error.PNG" alt="nxp error.PNG" /></span></P> Tue, 03 Oct 2023 09:24:48 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Enquiry-on-Programming-LPC5536-MCU-in-ISP-mode-using-Flash-Magic/m-p/1733014#M54263 Cheok98 2023-10-03T09:24:48Z Re: Enquiry on Programming LPC5536 MCU in ISP mode using Flash Magic tool https://community.nxp.com/t5/LPC-Microcontrollers/Enquiry-on-Programming-LPC5536-MCU-in-ISP-mode-using-Flash-Magic/m-p/1733046#M54264 <P>If you have disabled your JTAG/SWD interface, you would need to start it into ISP mode (System Mode), to go into the ROM bootloader and prevent your application from taking control.</P><P>I don't know your board/MCU, usually you need to set a specific jumper.
