ADAU1467 not programming with SPI and TCP/IP.
Hello
I’m a bit lost in trying to find a solution why the DSP is not programming with my own written software.
My setup: Sigmastudio+ 2.4.0 TCP <->connected with my own board <-> SPI <-> EVAL-ADAU1467Z.
When I try to make a download with the USB tool (Delivered by the board.) everything works fine! The DSP is returning 0x02. I captured the DataStream and added this to this topic. When I do the same at the TCP side, the DSP is always return 0x03, when I review the datasheet it means “Core is in sleep mode (the core may be actively running a program, but it finishes executing instructions and waits in an idle state for the next audio sample to arrive). This state occurs only if a sleep instruction is explicitly called in the DSP program.”
What do I wrong? When I capture the SPI data between myboard and the DSP the data looks the same as I download with the USB tool.

Hello JDWBE,
I guess you are reading the CORE_STATUS register (0xF405) right?
It's normal and expected to get the value 0x3 as the result. But I'm not sure why you are getting 0x2.
when you read this register, and if it says ''the core is not running'', then the core is not running. you should have to check for the reason in that situation.
All the other values can happen during operation and do not mean there is a problem. In your case, when you read the register, you get the 'core is sleeping' and when I tried with a pass thru program in my eval board, I also got the same.
The core status of 'core running' means it is running the program. Once the program finishes running for the sample period. The core will go to sleep to wait for the next frame interrupt. So, if the program is small, it is actually difficult to catch the core when it is running the program, it is easy to catch it as it is sleeping since the majority of the sample period it is done with the program and it's sleeping and waiting for the next interrupt (because our program is very small).
if you want to verify if the core is running, then add a DC cell and readback cell in your schematic and try reading the readback cell's value or simply put an LED blink program and see if the core is running continuously.
If you are reading back the correct value or LED is blinking normally, then there will not be a problem.
If you still have an issue, then you can try using sigma studio 4.7 once and see how it behaves.

Harish
Many thanks for your answer and suggestion.
Another thing that is not yet clear for me.
What is the correct way to answer on a “Read Request format”?
For example:
SPI communication from controllerto DSP: 0x01, 0xF4, 0x05, 0XFF, 0xFF. Response from DSP to controller: 0xFF, 0xFF,0xFF, 0x00, 0x01. Do I need the send the 0xff as well in the data payload? Or only the 0x00, 0x01?
Data length of 0x02 and 2 bytes of payload.
After some debugging and switching to Sigmastudio 4.7. I’m stuck.
When I try to debug I got some problems with translation. See attachment. When Sigmastudio fires a saveload, the data inside sigma and Wireshark is not the same?!
What do i wrong?
