Hi @diegargon |
|
Just mention i buy your device months ago, coral work fine but only show one, 00:00.0 Host bridge: Intel Corporation Xeon E7 v4/Xeon E5 v4/Xeon E3 v4/Xeon D DMI2 (rev 01) |
|
@diegargon with
If nothing helps, please contact for adapter replacement |
|
Will check report that now, and probably take some photos |
|
there is about 3 contact that seems looks good, one is missing. is not right? or is missing for some other reason |
|
Missing some (unused) contacts on TPU card is totally fine. You can use official images as reference to compare with |
|
and the one missing in the adapter? the reference image seems have all contacts |
Hello.
