I think it may be a chip issue.How to solve this problem?Thanks.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:42:01 GMT https://community.nxp.com/t5/LPC-Microcontrollers/lpc4357-crash-at-204Mhz-at-the-beginning/m-p/557642#M15448 lpcware 2016-06-15T18:42:01Z Re: lpc4357 crash at 204Mhz at the beginning https://community.nxp.com/t5/LPC-Microcontrollers/lpc4357-crash-at-204Mhz-at-the-beginning/m-p/557643#M15449 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by mc on Sun Jul 05 16:54:47 MST 2015</STRONG><BR /><SPAN>Hi,</SPAN><BR /><SPAN>The frequency should be increased in steps.
