Compiler/CC2540: What is the exact location of SNV area in cc2540?

I expected to see the SNV area on last two pages starting from 0x3F000 to 0x3FFF as CC2540-BLE-Document says. But in the .map file, I see that it starts from 0x3E800 (i.e. a page earlier). If so I'm wondering what is the content the last page (starting from 0x3F800)?

The flash lock bits are stored there. See hal_board_cfg.h:

// The last 16 bytes of the last available page are reserved for flash lock bits.
#define HAL_FLASH_LOCK_BITS 16

Hi,

Thank u for your answer.

i ask, if the only think that i need to do is adding the - #define HAL_FLASH_LOCK_BITS 16 in hal_board_cfg.h file?

Thanks

Thank you for your response. You are saying we are allocating 2K for keeping just 16 bytes for flash lock?
