26.7.11 IAP Status Codes
26.8 Debug notes
26.8.1 Comparing flash images
Depending on the debugger used and the IDE debug settings, the memory that is visible
when the debugger connects might be the boot ROM, the internal SRAM, or the flash. To
help determine which memory is present in the current debug environment, check the
value contained at flash address 0x0000 0004. This address contains the entry point to
the code in the ARM Cortex-M0 vector table, which is the bottom of the boot ROM, the
internal SRAM, or the flash memory respectively.
26.8.2 Serial Wire Debug (SWD) flash programming interface
Debug tools can write parts of the flash image to RAM and then execute the IAP call
"Copy RAM to flash" repeatedly with proper offset.
