Technical issues about ADSP-BF518BBCZ4F16

Hi,

We are an IC programmer manufacturer, and we are trying to support ADSP-BF518BBCZ4F16 for one of our customers.

However, we are facing technical issues while developing ADSP-BF518BBCZ4F16, need your help to provide some suggestions.

Firstly, the attached picture is our socket adaptor circuit, please help to check if there is anything need to be modified.

Secondly, We used SPI mode to send read ID command (0x9F) to the IC but got no response from the IC. Do you have any idea with this issue?
