Original question:

BQSTUDIO: Problem using BQstudio with AMD computers

BQSTUDIO: issues on AMD platforms?

Part Number: BQSTUDIO
Other Parts Discussed in Thread: EV2400, , BQ76952, BQ34Z100
Dear Team,

We are running into a problem regarding BQstudio. We recently purchased a new company laptop. We find that for some reason BQ studio does not run at all. It seems unable to auto-detect any device that is connected to EV2400, we've measured it on a scope and it doesn't even attempt to communicate over I2C.
The peculiar thing is, if we connect any other laptop (we've tried 3 different models hp/dell/msi + an old desktop) they all work fine.
The main difference we could find is that the new laptop has an AMD cpu, everything used before that is Intel based.
Which leads us to wonder; does BQstudio have trouble with AMD platforms? We are using an AMD Ryzen 7 at the moment. The windows 11 install is only a few weeks old. We are using the same version of BQstudio as on the intel-based laptops/desktop, but nothing seems to be working.
It does seem to detect the EV2400 as 'HID' device in the device manager, similar to the intel laptops. But that's about the most we managed to squeeze out of the thing.

Does anyone at TI recognize this issue with AMD platform/chipset/driver etc? On the other hand, if you recognize this issue as something else entirely, please let me know.

Thanks!

    Hello Thijs, 

    Are you able to run bqStudio, and it is just not auto detecting the gauge you have connected? Can you please send an image of bqStudio when you load it and of the error? If bqStudio is loading fine and the only issue is that the gauge is not being autodetected, then I suspect the issue is that you just do not have the correct bqz file for the gauge you are using in the "config" folder of the bqStudio repo. We have tested bqStudio just now on a device with an AMD processor and bqStudio loaded fine. 

    Regards, 

    Jonny.

    Hi Jonny,

    Thanks for verifying it runs on AMD. We are using Zen3+ (7735hs), can you recall what you tested on?

    We can start the environment, but we never see the EV2400 do any attempt at auto-detecting. Usually we see some I2C bus traffic when we launch BQstudio. On this machine it does nothing.
    We are using "BQSTUDIO-TEST Version: 1.3.124 Release date: 03 Nov 2023" on a clean windows 11 install. 
    When we saw issues we installed https://www.ti.com/tool/download/SLUC291/01.00.00.00 as well.

    We tried IC's BQ76952 and BQ34Z100. On other machines these work when we install the BQstudio test version.

    One pretty weird thing; if we launch Bqstudio by just selecting a device from the list, the programmer is detected as a EV2300. Perhaps this is what is causing our issue? We still have no clue though, since we didn't follow any different steps for setting op BQstudio on this machine

    Hope we can resolve the issue. Thanks for your support!

    Hello Thijs, 

    This was tested on an AMD Ryzen 7 processor. What version of the EV2400 FW are you using? The latest version is v0.32 and can be downloaded here. Additionally, can you show how the EV2400 is enumerating in device manager? 

    Regards, 

    Jonny.
