EVMK2H: EVM startup issue

Kaustubh Kulkarni

Part Number: EVMK2H

A student ask,

" We purchased the EVMK2HX from your store but when running we always get message: "SoC Power Failure" while booting. We followed the instructions for re-flashing the BMC, we did it but without success. The kit still appears with the same problem and we are not able to connect to the board (we do not have IP) and to work with. We really need the find an answer why the board freezes and does not work even though we follow the workaround solutions and how to repair it. "

Could anyone help me this?

Thank you.

Check your board revision and see if the following workaruond will help:
wfcache.advantech.com/.../EVMK2HX_Rev4_0_Known_Issues.pdf
"2.5 SOC Power Fail
 Description: During power on of the board the UCD controller will detect a fault and will
abort the power on sequence
 Workaround:
1. Occasionally a successful “power on” will occur if multiple power cycles are
performed.
2. A script is in development to enable a field update to correct the UCD settings.

Management_Field_Update)
 Plans for a fix: Correct configuration will be programmed in future builds of EVMs "
