AFE7920EVM: Access to the LMK registers

Part Number: AFE7920EVM
Other Parts Discussed in Thread: AFE7920,

Hi Team,

I was wondering if there is a way in Latte to log the content of LMK registers, in a manner similar to what is already being done with AFE7920 registers.

At the moment in my script there is command 'lmk.logEn=1', but in the text file generated by Latte I am not able to identify if anything there contains LMK information.

Could you provide any insight on this?

Kind regards,

Željko

    Hi Željko,

    We suggest using TICS Pro (https://www.ti.com/tool/TICSPRO-SW) and not latte to generate the register configuration sequence for LMK parts. 

    Regards,

    Hi Vijay,

    Can you please provide some kind of TICS Pro setup file matching the LMK device on the AFE EVM?

    Honestly, in the first instance we just need a complete list of all the register writes that AFE EVM generates, and if Latte supports this feature I would prefer to use it first.

    Additionally, is there any kind of tutorial on how to work with TICS Pro and AFE7920EVM, especially since the connection to the on-board LMK is via FTDI?

    Introducing TICS Pro to the mix may result in additional debugging, as we are not aware how to setup the LMK device via TICS Pro in exactly the same way AFE does it.

    Kind regards,

    Željko

    Hi Zeljko,

    To readback the LMK writes in the AFE79xx GUI you can follow the instructions below.

    1. Add “lmk.logClassInst=logDumpInst” at line 154 in the devInt.py script.
    2. In EVM bringup script, add line: “lmk.rawWriteLogEn = 1” anywhere before line:” AFE.deviceBringup()”
    3. After running bringup the LMK writes will be logged as below.
