Flash Vector Table

This table contains the reset value of the stack pointer, and the start addresses, also called exception vectors, for all exception handlers. The first 15 exception vectors are necessary system exceptions, followed by a variable number of Interrupt Request (IRQ) vectors. The location of this table is fixed to address 0x00000000. At bootup time, the RTOS kernel will run a first function to initialize the Hwi module.

For more information about the vector table format, please refer to Cortex-M0 Vector Table.

For more information on the kernel boot process and first functions, please see FreeRTOS (RTOS Kernel) Overview.

Customer Configuration (CCFG) Table

The CCFG is placed at the end of the last flash page and lets the customer configure various chip and system parameters in the Customer Configuration (CCFG) table. The CCFG table is defined in ccfg.c in the provided examples. Parameters can be determined in the SysConfig (*.syscfg) file through the TI Devices → Device Configuration options. The last (sizeof(ccfg_t)) bytes of the CCFG sector are reserved by the system for the CCFG table. By default, the linker allocates the unused flash of the last flash page to the application image for code and data use.

See the CC23xx SimpleLink Wireless MCU Technical Reference Manual for details on CCFG fields and related configuration options, including how to set the CCFG to disable access to internal flash memory contents.

Note

The CCFG cannot be relocated, and must reside at the end of the last page of flash. Consult the CC23xx SimpleLink Wireless MCU Technical Reference Manual for more information.

Note

If SET_CCFG_ERASE_CONF_CHIP_ERASE_DIS_N is set to 0 it’s not possible to do mass erase.
