To save signals on an SD card, the target hardware details must be specified.
In your model window, open the Configuration Parameters dialog box, go to the Hardware Implementation pane, and select the name of the target hardware from the Hardware board list.
In the Hardware board settings pane, expand Target hardware resources and select SD card logging.
Select Enable MAT-file logging on SD card option.
For C2000™ hardware boards, it is advisable to limit the data points for the signals to be logged as C2000 hardware boards have limited memory. In case of memory allocation failure, set *Limit data points to last* to lesser than |512| value.
For F2803x, F2805x, F2833x, F280x and Concerto(35x and 36x) processors, select *Save format* as |Array| to avoid memory overflow.
From the SPI module list, select the desired SPI module.
The default values vary based on the Hardware board selected.
From the SPI baud rate list, select
Inherit from SPI settings - Inherits the
value from the Desired baud rate in
bits/sec set in the corresponding
Maximum achievable supported by the inserted SD
Card - The baud rate for SPI interface is
automatically selected based on the SD card inserted on the
C2000 hardware. In this case, the Desired baud
rate in bits/sec set in the corresponding
x pane is
