ADSP-21569 EZ-kit RESET after power on

Hi Sprak,

You have to connect the Sigma Studio USBi connector as shown in the below image.

Please provide the below details, this will help us to assist you further:

1. Is this the first time whether the heat up issue occurred after re-plug the Sigma Studio SPI connection in EV-21569-SOM board?
2. Whether this heat up issue occurring without connecting the Sigma Studio SPI connection also?

Also, check the jumper in SOM. If all fine, possibly there may be Hardware issue.

Hi Nishanthi,

For your questions:

1. It is not the first time re-plug, I have using this borad for half year, and this issue just happened.

2. It will be occurring without connecting Sigma Studio SPI connection.

3. The jumper in SOM only connected POWER, no anything else.

Thank you so much for assistence.

Hi Sprak,

From your response, we suspect that there could be some hardware issue in your setup.

Could you please answer the following questions, in order to accurately determine the cause for this issue:

1. Please share us the screenshot results of ICE Test utility. ICE Test utility can be used to test for faulty JTAG connections, as well as testing your hardware configuration.

2. If you have access to any other SOM/carrier board, could you please replace each other and check whether same heating issue occurred or not.

3. Please refer "Jumper and Switch Settings" in the below system evaluation manuals and ensure the jumper and switch settings are set correctly in the EV-21569-SOM and EV-SOMCRR-EZKIT boards:

4. Please let us know whether you have purchased the board directly from Analog Devices or from distributor.

Awaiting for your reply.

Hi Santhakumari,

Thank you sincerely for answering me. For your questions, 

1. ICE Test utility result as below.

2. I put the ISSUE SOM board to a new carrier board, the RESET light doesn't on. And I put the new SOM board to the ISSUE CARRIER board, the reset and hot issue comes up. So I think the carrier board is the problem.

3. For ISSUE SOM/carrier board when I put JP1 tu default possion, all the power is down and no issue happened.

4. I got this board directly from Analog Devices for applications development.

Thank you again for helping.

Best Regards,
