User manual
5.1.1 Criterion for Valid User Code
5.1 Memory map after any reset
When ISP mode is entered after a power on reset, the IRC and PLL are used to generate
CCLK of 14.748 MHz. This may not be the case when ISP is invoked by the user
application (see
The Flash portion of the boot block is 8 kB in size and resides in the top portion (starting
from 0x0007 E000) of the on-chip Flash memory. After any reset the entire boot block is
also mapped to the top of the on-chip memory space i.e. the boot block is also visible in
the memory region starting from the address 0x7FFF E000. The Flash boot loader is
designed to run from this memory area, but both the ISP and IAP software use parts of the
on-chip RAM. The RAM usage is described later in this chapter. The interrupt vectors
residing in the boot block of the on-chip Flash memory also become active after reset, i.e.,
the bottom 64 bytes of the boot block are also visible in the memory region starting from
the address 0x0000 0000. The reset vector contains a jump instruction to the entry point
of the flash boot loader software.
Criterion for valid user code: The reserved ARM interrupt vector location (0x0000 0014)
should contain the 2’s complement of the check-sum of the remaining interrupt vectors.
This causes the checksum of all of the vectors together to be 0. The boot loader code
disables the overlaying of the interrupt vectors from the boot block, then checksums the
interrupt vectors in sector 0 of the Flash. If the signatures match then the execution
control is transferred to the user code by loading the program counter with 0x0000 0000.
Hence the user Flash reset vector should contain a jump instruction to the entry point of
the user application code.
