Dear all, i have LPC1758 abd a structure fixed in rom like this:


__attribute__ ((section(".myText"))) const uint8_t arText[200];


Tastiera_Lcd_Debug_memory.ld:
..........
  MyText   (rx) : ORIGIN = 0x00068000, LENGTH = 0x8000 /* 32K */

Tastiera_Lcd_Debug.ld:
..........
.myText : ALIGN(4)
{ *(.myText)
} > MyText


When I program the flash entering in debug, the text array is initializated to 0x00, how can I not initialize the rom array ?


Thanks

OK Thanks Solved the problem with:

.myText (NOLOAD) : ALIGN(4)
{ *(.myText)
} > MyText

Assuming that you want to leave whatever values are already stored at that location, you should give the section the NOLOAD attribute in the linker script.
