I tried and build a project, with different CRP_WORD constant, see below
code snippets:
[FONT=Courier New]main.c:[/FONT]
:
[FONT=Courier New]#include <cr_section_macros.h>
#include <NXP/crp.h>
//__CRP const unsigned int CRP_WORD = CRP_CRP2;
__CRP const unsigned int CRP_WORD = CRP_NO_CRP ;[/FONT]
:
then I compared the result .hex files, I found the only difference is at
address 0x2FC: (As expected)
[FONT=Courier New]///// CRP_WORD = CRP_CRP2
:
:1002D000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF2E
:1002E000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF1E
:1002F000FFFFFFFFFFFFFFFFFFFFFFFF21436587BA
:
///// CRP_WORD = CRP_NO_CRP
:
:1002D000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF2E
:1002E000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF1E
:1002F000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0E
:
[/FONT]
But, when I built another project, with different CRP_WORD constant,
I got identical .hex files. I also found that at address 0x2fc, the space
seems are occupied by the object codes, not remained empty like pervous
project does:
[FONT=Courier New] :
:1002D0001080000080B582B000AF074A074BD358AA
:1002E0001A1CBB1D1A80044ABB1D1988044BD1502F
:1002F000BD4602B080BDC04600000250188000001C
:[/FONT]
What was wrong?
Any hints would be appreciated!
PS. My development tool is LPCXpresso v4.1.0
Both projects use CMSISv1p30_LPC11xx
