The product is Bay Lake CRB (Fab 1 Rev B) with an Intel Atom Valleyview 2 processor. The "Lordship Beach" AIC displays POST code 012F. The processor and the PMIC card have been reseated, however the issue still remains.
Thank you for contacting Intel Embedded Community.
Could you please provide pictures of the Customer Reference Boards (CRBs) labels and markings, also of the processor topside markings related to this situation?
Could you please clarify if you made any change in the configuration of the CRBs (such jumper position modifications, memory changes, or others) associated with this condition?
We are waiting for your answer to these questions.
I have a few photos of the board labellings and markings, shown below. I don't currently have a photo of the processor markings, however I can get those to you tomorrow. The CPU is well stuck to the bottom of the clamping mechanism with thermal paste and I haven't attempted to separate it from the mechanism so as not to damage the CPU BGA or the interposer on the board.
None of the jumper positions or DIP switch positions have been altered as far as I know.
Thanks for your update.
Based on the provided information, could you please clarify where you acquire the affected CRB?
Could you please explain if the processor showed on your last communication is the one provided with the CRB showed on your communication of yesterday or you change it?
We are waiting for your clarification.
Thanks for your reply.
We suggest verify that the processor is compatible with the CRB. This processor seems to be a sample device based on the few markings showed in the attached picture. Due to this fact, please address this verification by filling out the Embedded Samples Feedback form that can be found at:
By the way, the showed CRB is related to Cherry Trail or Bay Trail-T family devices.
It is important to let you know that unfortunately the Cherry Trail is on the "off-roadmap" and its support is for limited manufacturers. For this reason, this processor family is unsupported by this channel. Click on Cherry Trail website to learn more about the specifications of this family at the following website:
However, you can send your consultations related to this CRB by filling out the form stated at:
Thank you for the information. I have filled in the Embedded Samples Feedback form asking about the compatibility of the processor with this CRB and I am awaiting a response. Out of interest, do you happen to have to hand the specifications of this engineering sample processor? Also, would it be at all possible to see a list of POST codes for this board? I understand if this information is unavailable to me.
Thanks for your reply.

On the other hand, we would like to have the information related to Cherry Trail devices but unfortunately it is out of scope of support.
Due to this fact, please address your question of this type to the last website mentioned on our previous message.
