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

||||
