Other Parts Discussed in Thread: ALP, DS90UB971-Q1

971 EVMs are not being detected over USB. I have tried this with 2 971 EVMs. If we connect the 971 EVM via aardvark, we are able to detect it. Please see the snapshot below of the scenarios

Hi Navtej,

Welcome to E2E!

Could you clarify which EVM you are referring to and re-upload the snapshot you mentioned? I do not see it in the original post.

Thank you!
Best Regards,
Ashley

Hi Navtej,

Thanks for the clarification - no problem! I have re-assigned this thread to our FPD-Link team who owns this EVM and they can assist further.

Regards,
Ashley

Hi Navtej,

The DS90UB971-Q1 and its EVM are NDA devices. We do have a product page on ti.com with limited information on the 971 device, but would prefer not to discuss this NDA device and EVM in detail over the public forum.

Could you reach out to a local TI FAE and ask them to post your question on your behalf in our internal NDA E2E forum?

Best,

Justin Phan
