Even if you could, there is no way for you to run from there.</SPAN><BR /><BR /><SPAN>As LPC4370 is flashless, you either run from RAM, SPIFI or external memory.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:27:59 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543775#M12753 lpcware 2016-06-15T18:27:59Z Re: Programming LPC4370 https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543776#M12754 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by mshrestha789 on Tue Mar 10 07:29:16 MST 2015</STRONG><BR /><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I read from user manual that for flashless controller, boot code can be store in the internal ROM memory and the ARM processor will start its code execution from this memory. So how do we do that? Can you please guide me on this. Do we need external memory to download and run code? </SPAN></BODY></HTML> Wed, 15 Jun 2016 18:27:59 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543776#M12754 lpcware 2016-06-15T18:27:59Z Re: Programming LPC4370 https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543777#M12755 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by TheFallGuy on Tue Mar 10 07:44:09 MST 2015</STRONG><BR /><SPAN>You must have misunderstood the manual.</SPAN><BR /><BR /><SPAN>There is a boot ROM in the chip. This is ROM and is impossible for you to change.</SPAN><BR /><SPAN>For a flashless part, such as the LPC4370, you have to use external flash to store your code. There is an alternative of booting from USB using DFU, where code is downloaded to internal RAM - but you need a host connected to USB so that it can dfu-boot your device.</SPAN><BR /><BR /><SPAN>Maybe you want to use one of the parts with internal flash, such as the LPC4357?</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 18:28:00 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543777#M12755 lpcware 2016-06-15T18:28:00Z Re: Programming LPC4370 https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543778#M12756 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by mshrestha789 on Tue Mar 10 08:38:52 MST 2015</STRONG><BR /><SPAN>Ok Thank you so much. Yes I misunderstood the manual. Now I'll interface SPIFI flash memory and try again. </SPAN></BODY></HTML> Wed, 15 Jun 2016 18:28:01 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Programming-LPC4370/m-p/543778#M12756 lpcware 2016-06-15T18:28:01Z
