$ artiq_coreconfig -f idle_kernel idle.elf
|

$ artiq_coreconfig write -f idle_kernel idle.elf

To read the record whose key is ``mac``::
|
||||
|
||||
$ artiq_coreconfig -r mac
|
||||
$ artiq_coreconfig read -k mac
|
||||
|
||||
To write the value ``test_value`` in the key ``my_key``::
|
||||
|

$ artiq_coreconfig -w my_key test_value
|

$ artiq_coreconfig -r my_key

$ artiq_coreconfig read -k my_key

|

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 -f idle_kernel idle.elf
|
||||
$ artiq_coreconfig -r idle_kernel | head -c9
|
||||
$ artiq_coreconfig write -f idle_kernel idle.elf
|
||||
$ artiq_coreconfig read -k idle_kernel | head -c9

|
||||
|

You can write several records at once::
|
||||
|
||||
$ artiq_coreconfig -w key1 value1 -f key2 filename -w key3 value3
|
||||
$ artiq_coreconfig write -s key1 value1 -f key2 filename -s key3 value3
|
||||
|
||||
To remove the previously written key ``my_key``::
|
||||
|
||||
$ artiq_coreconfig -d my_key
|
||||
$ artiq_coreconfig delete -k my_key
|
||||
|
||||
To erase the entire flash storage area::
|
||||
|
||||
$ artiq_coreconfig -e
|
||||
$ artiq_coreconfig erase
|
||||
|
||||
You don't need to remove a record in order to change its value, just overwrite
|
||||
it::
|
||||
|
||||
$ artiq_coreconfig -w my_key some_value
|
||||
$ artiq_coreconfig -w my_key some_other_value
|
||||
$ artiq_coreconfig -r my_key
|
||||
$ artiq_coreconfig write -s my_key some_value
