Then, provided I keep the board powered and plugged into the link, I can stop LPCxpresso and start Keil with the CMSIS DAP selected as debugger and off I go. But Keil can't find the debugger from a power up of the board directly - and neither the debugger or the com port appear as devices to the (windows) computer that I'm running on.</P><P>Is there a way to cause the init of the debugger and serial port without using LPCxpresso to boot it?</P><P>I've also pinged ARM because this sounds like a driver issue in part (which is not the MCUXpresso fix if anyone is following that thread - it doesn't help).</P> Tue, 02 Mar 2021 18:12:52 GMT https://community.nxp.com/t5/LPC-Microcontrollers/CMSIS-DAP-UART-and-KEIL/m-p/1238844#M44105 ianholmes 2021-03-02T18:12:52Z https://community.nxp.com/t5/LPC-Microcontrollers/CMSIS-DAP-UART-and-KEIL/m-p/1249985#M44390 <P>Hello,</P> <P>How about this case now, yes, I think you can find help from KEIL support.</P> Tue, 23 Mar 2021 02:49:32 GMT https://community.nxp.com/t5/LPC-Microcontrollers/CMSIS-DAP-UART-and-KEIL/m-p/1249985#M44390 Alice_Yang 2021-03-23T02:49:32Z
