Hi,

i'm programming LPC2468 CPU. I'm tryng to enable CRP without success.
I choice the correct level protection in the CRP.c file and added the symbol
in the symbol directive. I also enable "Enable Code Read Protection" in linker script
section but seem to have no effect. Reading the hex file seem that the setting of
the CRP is not set correctly (my choice is CRP_NO_ISP    0x4E697370) point but however the CRP don't work. I post the hex file that show that there is no CRP enabled:

:1001F000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0F

my CRP in correct memory location, but when i program my CPU by FLASHMagic and i
