Hi Team,

I have few questions regarding stm32h7 errata.

  1. Errata 2.2.21, Can silicon revision 'V' support a cpu frequency of 480 Mhz ? If yes, why is it showing 'P' for v revision.

  2. Can I please ask if there is a fix in the HAL for the below given SPI errata  (from 2.22.2 to 2.22.6)?

    Hi,

    1. >stm32h74

    is no cpu .

    I have H743 , can reach 480M ; and H7S3 , can reach 600M .

    So ask exactly for a model...

     

    2. fix or no fix or "workaround" should be clear from the errata, specific to the cpu model+revision.
