Hi all,

The LCD displayed  "Main Power Failure" on K2HEVM. My rescue steps as follows.

1. Update BMC to latest version 1.0.2.5

    Here was my console log.

2. Update UCD module

     I encountered "I2C Operation Timeout" when wanted to update the configuration files.

     Here was my console log.

May I say this K2HEVM need to request Advantech for repair process? Thanks in advance.
