Dear Team,

We received the attached problem description from one of our customers who is facing some communication issues with the TPS65982-EVM.

Could you please advise?

Thank you in advance.

Kind Regards,

    Mo,

    It looks like the FW running on your EVM is pretty old. The Version Register is returning 0x01.01.00 and the latest FW Version is 0x01.11.02

    We only increment to odd digits in the minor Rev. (i.e. 01.01, 01.03, 01.05,...) but this still means the FW is 5 Minor revisions old. Those commands may not have been supported in the 01.01.00 FW build and this is why the part is returning '!CMD'.

    Can you try using FW generated in the latest TPS6598X-CONFIG Tool?

    Hello,

    if we understand correctly, firmware (boot code) is embedded directly in the chip memory and application code is embedded on external flash memory? Version register is for this bootloader code or for application code?

    We tried flash our second hardware (chip with older firmware version (0.08.10)) with firmware generated from your tools.
    Flashing procedure went (probably) ok, but application doesn't boot properly ( [6:6] Region0Invalid True, [7:7] Region1Invalid True):

    Did you follow the directions for overwriting the Flash IC memory directly using a TotalPhase Aardvark, as described by the TPS65982-EVM User's Guide?

    I also cover this topic in a training video on the new TPS6598X-CONFIG Tool, titled TPS65982 Config Tool Upgrade - SW & FW Training
