TMDX654IDKEVM: Board revision

Part Number: TMDX654IDKEVM

Hi Team,

Can you please help us with our customer's inquiry below.

I noticed in your documentation that there are four difference revisions A, B, E3, and E4. How do I know what revision board I have? Below is some information on the boards on 3 of the 5 boards I will work on getting the 2 last boards information. I need to find out what revision the boards are either A, B, E3, or E4 so I can reference the correct BOM and procedure for working threw the hardware clock issues. 

Board 1
OPN# TMDX654IDKEVM
SL# 44214P810083

Board 2
OPN# TMDX654IDKEVM
SL# 44214P810172

Board 3
OPN# TMDX654IDKEVM
SL# 44214P810223

I am trying to get the hardware clock to since with the internet. The instructions starting on page 75 for the known clock issues don’t seem to match my board of where they want me to change out resistors. I am reviewing ti-devkit-userguide SPRUIM6A – OCTOBER 2018 – REVISED NOVEMBER 2020 and the circuitry shown in the pictures locating the resistors do not match the locations of the physical resistors on my board. Is there a different updated set of instructions.

Please see the attached info. I need to be able to connect to the internet with ethernet and the hardware clock match with the software clock, do you have a procedure for my board?.
