This is the buffer used to copy and restore the content of each SRAM section under test. The first SRAM_SEC_SIZE bytes of SRAM are reserved for the buffer. The address specified for data memory objects must be 0x800000 plus the SRAM start address.

volatile uint8_t checkerbrd_buffer [SRAM_SEC_SIZE] __at(
    0x800000+ CHECKERBOARD_BUFFER_OFFSET
)

Returns

uint8_t checkerbrd_buffer [SRAM_SEC_SIZE] checkerboard buffer
