LPC804 MCU has CRP (Code Read Protection) function.
The CRP is located at address 0x0000 02FC, and there are different security levels NO_ISP/CRP1/CRP2/CRP3.
How to program security configuration? Is it only through ISP mode?
It can also be configured in the project project, as shown below in the MCUXpresso IDE, to enable CRP:
Configure CRP in the MCUXpresso project.
• Define appropriate CRP values for settings
• Use a custom script to configure the linker to place this constant at the CRP memory address (0x2FC), below defining the constant assigned to its desired CRP level. The attribute directive ensures that the linker places the constant (CRP_WORD) in a special ".crp" section of memory, the reference code is below.
#define CRP_NO_CRP 0xFFFFFFFF
#define CRP_NO_ISP_MAGIC 0x4E697370
#define CRP1_MAGIC 0x12345678
#define CRP2_MAGIC 0x87654321
/**Note: When setting CRP3, the read and write of the device will be locked**/
/*** #define CRP3_MAGIC 0x43218765 ***/
#define CURRENT_CRP_SETTING CRP_NO_CRP
__attribute__ ((section(".crp"))) const uint32_t CRP_WORD = CURRENT_CRP_SETTING;
