Is there any conflict b/w code on on-chip and code on external flash. And now I replaced the controller with new one it is working fine in on-chip mode so is there any configuration to do for not to use on-chip memory. </SPAN></BODY></HTML> Wed, 15 Jun 2016 18:06:50 GMT https://community.nxp.com/t5/LPC-Microcontrollers/how-to-program-off-chip-memory-without-using-on-chip-memory/m-p/524264#M6900 lpcware 2016-06-15T18:06:50Z Re: how to program off-chip memory without using on-chip memory https://community.nxp.com/t5/LPC-Microcontrollers/how-to-program-off-chip-memory-without-using-on-chip-memory/m-p/524265#M6901 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by mc on Thu May 29 09:06:17 MST 2014</STRONG><BR /><SPAN>Hi Shekar,</SPAN><BR /><SPAN>How did you program external memory?&nbsp; How are you splitting code between internal and external memory? Does it show the memory address which cannot be accessed?</SPAN><BR /><SPAN>More detail will be required to understand the problem. Can you also post your project? Did you try programming external memory with newly replaced chip?</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 18:06:51 GMT https://community.nxp.com/t5/LPC-Microcontrollers/how-to-program-off-chip-memory-without-using-on-chip-memory/m-p/524265#M6901 lpcware 2016-06-15T18:06:51Z Re: how to program off-chip memory without using on-chip memory https://community.nxp.com/t5/LPC-Microcontrollers/how-to-program-off-chip-memory-without-using-on-chip-memory/m-p/524266#M6902 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by SHEKAR MJ on Thu May 29 20:59:14 MST 2014</STRONG><BR /><SPAN>My code size is around 1.2MB so I dont want to use on-chip memory So I m dumping all program to external flash SST39vf1601 which is having 2MB size&nbsp; through JTAG So If I again want to put modified code It is showing cannot access memory So is there any setting or configuration to do check the attached images.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:06:51 GMT https://community.nxp.com/t5/LPC-Microcontrollers/how-to-program-off-chip-memory-without-using-on-chip-memory/m-p/524266#M6902 lpcware 2016-06-15T18:06:51Z
