ADAU1452 doesn't start execution of program
Hi there, I've designed a custom PCB with an ADAU1452 DSP. There is also a Linux SOM, a Codec for ADC/DAC and two MAX98397 on the PCB. Right now I'm trying to get the DSP to work. I've programmed a ba

DSP Core not run
Dear, I have already used the ADAU1452 DSP in several designs. But , for a new design I have a problem with the DSP core. I am using SPI communication to the DSP slave comms port and I try to read reg

ADAU1467 - CORE_STATUS = 0
I recently received our new digital audio board which is equipped with an ADAU1467. We have an external master clock signal running at 24.576MHz, 3.9V pk-pk. Verified that we have the master clock on

Need to expand SigmaStudio State C beyond 9999999 bytes
Hello, We are developing a product using SigmaStudio 3.12 for SHARC and the 21489 DSP. We are planning on using an external SD RAM (512MB) for a pooled audio delay. Here is an earlier thread: Running

How to access to the parameters values?
Hi all, I'm still in a stuck mode, trying to understanding the DSP world. I own a 21489 demo board. By the Sigma Studio I drawn a schematic and by the CrossCore ES I'm writing C code to control some i

ADAU1452: core status paused
Hi, on a custom design I'm not able to make the ADAU1452 to work since the core is always in pause state. By reading the register CORE_STATUS 0xF405 the returned value is 2. The same design on the eva

ADAU1772 core_fs bits
Hi, I'm refering to ADAU1772 data sheet rev.C and SigmaStudio 3.11 to confirm the operation and noticed that if I creat project file, the core_fs bit is set as 96kHz. And I can't find a control to cha

MultiPurpose pin jitter on ADAU144x
I'm finding that I can't get a stable fast (10kHz) square wave out of the MultPurpose pins on my ADAU1445. My scope is telling me it's rock solid 10kHz but I see it scooting around. When I use the pin
