Hello,
I'm having difficulty storing a custom DSP program so that it remains when the board is turned off and on again. I did this:
1. remove selfboot jumper
2. programmed DSP with SigmaStudio
3. powered down the board
4. replaced selfboot jumper
5. powered up board
The music sounds terrible with a high pitched zing until I reprogram with SigmaStudio, then it sounds good again (until it restarts).
What am I doing wrong?
Thanks,
David.
Hi David,
is your program deployed from SigmaStudio? I mean: Are you sure SigmaStudio programmed the DSP? If something fails, SigmaStudio often does not throw an error. You just notice that it does nothing.
Did you also program the EEPROM. Just programming the DSP doesn't program the EEPROM, you need to do this seperately.
Best regards,
Daniel
Thanks Daniel - I eventually figured out the problem. I needed to power up the board after I'd removed the selfboot jumper (step 1.5 above). Seems kinda obvious now.
