Hello,

With the following link I saw how you can place functions in a different flashbank.

https://www.lpcware.com/content/faq/lpcxpresso/coderodata-different-flash-blocks

But when I have a lot functions this is quite some work to add this to all of them.
Would it also be possible to define for an entire file it has to go there?

Hello gvandenbosch,

At the moment i am struggeling with the same. We have a spifi flash memory where we want to put certain parts of our code. Actually i am looking for a solution where we can put whole files or maybe even folders (all files in it) to a certain flash area.

Does anyone experience with this? Would be of great help!

Thanks!

If you are using LPCXpresso IDE, then please see:

I am not using LPCXpresso IDE but Eclipse with own basic LD file in there.

From your answer I understand it is possible, do you maybe have a pointer how to do this within a LD file without LPCXpresso?

I tried the following, but once the code jumps there it breaks:

MEMORY
{
  ROM1 (xrw)     : ORIGIN = 0x1A000000, LENGTH = 512K
  ROM2 (xrw)     : ORIGIN = 0x1B000000, LENGTH = 512K
  RAM (xrw)       : ORIGIN = 0x10000000, LENGTH = 32K
  RAM2 (xrw)   : ORIGIN = 0x10080000, LENGTH = 40K
}

.text2 : 
  {
  . = ALIGN(4);
  _stext2 = .;        /* create a global symbol at data start */
  
  ./test/test.o 
  . = ALIGN(4);
    _etext2 = .;        /* define a global symbol at data end */
  } > ROM2

Cheers,
Gerard

You have put the ENTIRE file into the text2 section (code and data). You need to do something like this, you to put just the code into that section:

./test/test.o(.text*)
