Relevancy between silicon errata and these issues

Hi

Do you think TM4C silicon errata(www.tij.co.jp/.../spmz850f.pdf) occur issues below?

- makes booting slower

- makes beep sound lower

- makes USB connecting unstable

- makes timer counting slower

We guess it has some relevance with SYSCTL#22, SYSCTL#23.

    Yuji,

    The Errata (spmz850f.pdf) lists the workarounds for SYSCTL#22, and SYSCTL#23.Please use the workaround, then check if the issues occur again.

    QJ,

    Thank you for your reply. I agree with you, but it is difficult to identify whether this errata occur these issues or not. Because, these issues occur on low probability originally. I think this errata causes the frequency to be faster. Do you think is there any probability(or any case) of this errata causes the frequency to be slower?

    Regards,
    Yuji
