AM62A7: Workaround for Errata in MCU+SDK

Part Number: AM62A7

Hi Support team,

Could you please confirm if workarounds for the following errata are already implemented in MCU+ SDK?

 If yes, please specify the MCU+ SDK version where these were introduced:


i2310 — USART: Erroneous clear/trigger of timeout interrupt
i2311 — USART: Spurious DMA Interrupts
i2431 — BCDMA: RX Channel can lockup in certain scenarios
i2436 — BCDMA: BCDMA RX_IGNORE_LONG setting in RX CHAN CFG register doesn't work

Thanks and Regards,
Gurumoorthi K

    Hello Gurumoorthi K,

    Errata i2310 has been fixed in MCU+ SDK version 09.02.00 and is automatically handled by the UART driver . No customer action is required.
    Errata i2311 requires customer attention to ensure proper configuration of UART FIFO trigger levels when using DMA operations in the Application side . Use power-of-2 trigger levels for the software workaround .
    Errata i2431 and i2436 do not apply to UART operations as the MCU+ SDK UART driver uses PKTDMA channels instead of BCDMA channels.

    Regards,

    Anil.
