TAS2555YZEVM: PPC3: Loading I2C Parameters & Initialization in 'Tuning Mode' gets stuck -> Restart PPC3

Part Number: TAS2555YZEVM
Other Parts Discussed in Thread: TAS2555

Hello, all together in this forum,

we got a Problem with the TAS2555YZEVM and PPC3 V3.1.4:
Initialization of the TAS2555 in ROM Mode 1 or ROM Mode 2 works fine, but when initalizing it in Tuning Mode, PPC3 gets stuck.
First, PPC3 is sending a huge mass of register content through the I2C.

After ~1minute PPC3 seems to have finished the I2C stuff and then gets stuck in the 'Updating Components' stage of the process:

What can i do to fix this problem. Anyone else concerned with this? Any experiences?
Any help is appreciated.

Kind regards

    Update: I found this thread

    e2e.ti.com/.../687280

    dealing with the issue. Thanks to Matsumoto-San's findings i reinstalled the PPC3.

    But after downloading it gets stuck with this message:

    How shall i deal with this issue? Apparently it's not a download problem, but how to handle the 'Component File Version doesn't match' - error?

    Any help is appreciated.

    Kind regards

    Hi Andreas,

    Can you provide an email address so I can contact you offline? Or you can also send me a message to: ivan.salazar@ti.com

    Our SW team is currently working to fix this error during PPC3 installation, in the meantime:

    • We can provide a previous version of the installer
    • Or you can download and install Matlab Compiler Runtime separately, if it is already installed you can check if it is configured correctly following the attached slides

    Hello, Ivan,

    thank you for your fast reply. I will try to manually install the MatLab runtime compiler. And use your
    slides to fix the env. vars. if needed.
    Besides, my email address is
    a.paulin@csslabs.de.
    So you can send me the previous version of the installer in case it doesn't work.

    I'll keep you informed how things run..

    Kind regards

    Andreas Paulin
