Double check your memory map usage by both cores.</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>LPCXpresso Support</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 19:01:15 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Multi-core-project-error-with-USB/m-p/576290#M19410 lpcware 2016-06-15T19:01:15Z Re: Multi-core project error with USB https://community.nxp.com/t5/LPC-Microcontrollers/Multi-core-project-error-with-USB/m-p/576291#M19411 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by turiB on Fri Feb 12 07:42:38 MST 2016</STRONG><BR /><SPAN>Thank you for the reply.
