The firmware license is the license which is required for operation of each DHD core or DSP frame.
Usually, the cores will be delivered without a firmware license. This firmware license will be sent via e-mail.
After loading the firmware license into the device it is permanently stored in a separate flash memory. The firmware license will not be stored on the microSD card.
Note
An invalid license code allows unlimited operation of a device for 600 operating hours, this corresponds to 25 days non-stop operation. After that, the message License invalid is shown in the module display. Apart from this message, the mixer operation is still unlimited. After 800 hours of operation without license, the system is interrupted by a random reset approx. once per hour.
