to E2Prom has not been completed), remove power from the DSPB, disconnect the ICP1 and
reconnect power to the DSPB.
B. Writing to E2Prom – Burning custom SigmaStudio programs to non-
volatile (non-temporary) memory
This step writes your custom program to non-volatile memory on the DSPB, which ensures that your
custom program runs on the DSP upon a new boot. This is essential for long term use, because when
you are connected to SigmaStudio testing configurations, that current program is stored in memory that
is volatile or temporary, meaning it is lost when there is a power cycle. If you find that your program is
lost on a power cycle, it means you have not written the program to E2Prom.
IMPORTANT – This step will erase the stock configuration of the board! This means that the default
functions of POT1-4 will reprogrammed or removed, depending on the SigmaStudio project that is
loaded.
There is a project file on the websi te called “Stock_Firmware.dspproj” that will restore the
original firmware if you need It.
1. If choosing to do this step, it is highly recommended to tie one of the potentiometers of the
board to a master gain control (demonstrated in “ Creating a basic SigmaStudio project for the
DSPB ” above). Without this, it will not be possible to control gain without reconnecting to
SigmaStudio.
2. By this step, you should have successfully created a project and programmed it onto your DSPB
during the same session of SigmaStudio during which you will be writing to E2Prom. If you have
not successfully used the “Link Compile Download” button, you must before moving foward.
3. Right click your “ADAU1701” block and click “Write Latest Compilation to E2PROM”
4. In the window that opens, make sure the settings match what is in the screenshot below (they
are the default settings), and press OK.
a. NOTE: The ICP1 switch’ s position must be at ‘1’ for this to work properly. If you get to
this point and realize it is set to ‘2’, you might be required to refollow the ICP1 sigma
studio connection guide again in order to write to E2Prom. Alternatively, try pressing
the reset button on the ICP1 after switching to ‘1’.
