Core device configuration tool
------------------------------
Core device access tool
-----------------------
The artiq_coreconfig tool allows to read, write and remove key-value records from the :ref:`core-device-flash-storage`.
The artiq_coretool utility allows to perform maintenance on the core device:
It also allows to erase the entire flash storage area.
* read core device logs;
* as well as read, write and remove key-value records from the :ref:`core-device-flash-storage`;
* erase the entire flash storage area.
To use this tool, you need to specify a ``ddb.pyon`` DDB file which contains a ``comm`` device (an example is provided in ``artiq/examples/master/ddb.pyon``).
This tells the tool how to connect to the core device (via serial or via TCP) and with which parameters (baudrate, serial device, IP address, TCP port).
When not specified, the artiq_coreconfig tool will assume that there is a file named ``ddb.pyon`` in the current directory.
When not specified, the artiq_coretool utility will assume that there is a file named ``ddb.pyon`` in the current directory.
To read the record whose key is ``mac``::
$ artiq_coreconfig read mac
$ artiq_coretool cfg-read mac
To write the value ``test_value`` in the key ``my_key``::
$ artiq_coreconfig write -s my_key test_value
$ artiq_coreconfig read my_key
$ artiq_coretool cfg-write -s my_key test_value
$ artiq_coretool cfg-read my_key
b'test_value'
You can also write entire files in a record using the ``-f`` parameter. This is useful for instance to write the ``idle`` kernel in the flash storage::
$ artiq_coreconfig write -f idle_kernel idle.elf
$ artiq_coreconfig read idle_kernel | head -c9
$ artiq_coretool cfg-write -f idle_kernel idle.elf
$ artiq_coretool cfg-read idle_kernel | head -c9
b'\x7fELF
You can write several records at once::
$ artiq_coreconfig write -s key1 value1 -f key2 filename -s key3 value3
$ artiq_coretool cfg-write -s key1 value1 -f key2 filename -s key3 value3
To remove the previously written key ``my_key``::
$ artiq_coreconfig delete my_key
$ artiq_coretool cfg-delete my_key
You can remove several keys at once::
$ artiq_coreconfig delete key1 key2
$ artiq_coretool cfg-delete key1 key2
To erase the entire flash storage area::
$ artiq_coreconfig erase
$ artiq_coretool cfg-erase
You don't need to remove a record in order to change its value, just overwrite
it::
$ artiq_coreconfig write -s my_key some_value
$ artiq_coreconfig write -s my_key some_other_value
$ artiq_coreconfig read my_key
$ artiq_coretool cfg-write -s my_key some_value
$ artiq_coretool cfg-write -s my_key some_other_value
$ artiq_coretool cfg-read my_key
b'some_other_value'
