Introduction
The standard DVK Debug Adapter not only serves
development needs, it may also be used in production for in
circuit programming, thanks to the scriptability of its
supporting software. This application note describes this
usage mode.
Hardware Requirements
Figure 1 shows the DVK Debug Adapter and the debug
connector pinout. Customer hardware needs to make
provisions to connect at least GND, PB6, PB7, DBG_EN
and RST_N to the debug adapter. PB3 is recommended, but
not strictly required. The customer circuit may either be
powered from the debug adapter (provided it requires less
than 50 mA), or be powered by customer circuitry. In the
latter case, customer circuitry must ensure that the device is
powered during the entire programming process.

Software Usage
Axsem provides a command line tool that makes the
programming process fully scriptable. In order to run the
commands described below, a command shell must be
opened (Win+R cmd8 under some versions of Windows).
The basic command to program the microcontroller
FLASH memory is as follows:
axsdb.exe −−oldkeys key −−newkey key −−flashprog file
file is the file name (including the path) to the file
containing the microcontroller code. It may either be an Intel
Hex file (extension .hex), an OMF−51 file (extension .omf),
or an UBROF 10 file (extension .ubr). The file is usually
located in the bin\Release subdirectory of the
AxCodeBlocks project. If using SDCC, either the .hex or the
.omf file may be used interchangeably. If using IAR ICC,
then only the .ubr file is generated.
key is a 64 bit hexadecimal number (format
0x0123456789abcdef). This option locks the debug
interface to unauthorized access. After this command
succeeds, the debug interface may no longer be accessed
unless the key number is known. It is strongly recommended
that customer chooses a random number for key and keeps
it secret.
The command returns success / failure status as exit code.
The exit code is stored in the pseudo variable %errorlevel%.
It is 0 on success and 1 on failure.
Another useful command is the following, which sends a
reset pulse to the microcontroller:
axsdb.exe −−hwreset
If it is desired to reset the key of a locked microcontroller,
the following command can be used:
axsdb.exe −−oldkeys key −−newkey 0xffffffffffffffff
−−flashprog file
It is important that whenever the flash is programmed,
−−oldkeys key1,key2... is given with all possible keys the
microcontroller could be locked with. Otherwise,
calibration data is lost.
