Without crystal you have to use internal RC oscillator.</SPAN><BR /><SPAN>Of course switching to ISP is always using internal RC oscillator, so empty chips are working without problems with JTAG/SWD.</SPAN></BODY></HTML> Wed, 15 Jun 2016 17:26:27 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Does-JTAG-work-without-external-oscillator/m-p/516195#M1541 lpcware 2016-06-15T17:26:27Z
