MSP432E401Y: Does errata ETH#02 exist in MSP432E devices?

Part Number: MSP432E401Y

I notice that simplelink_msp432e4_sdk_4_10_00_13/source/ti/drivers/emac/EMACMSP432E4.c contains the following errata work-around:

    /*
     *  This is a work-around for the EMAC initialization issue found
     *  on the TM4C129 devices. This can be found in the silicon errata
     *  documentation spmz850g.pdf as ETH#02.
     *
     *  The following disables the flash pre-fetch (if it is not already
     *  disabled).
     */
    ui32FlashConf = FLASH_CTRL->CONF;
    if ((ui32FlashConf & (FLASH_CONF_FPFOFF)) == false) {
        enablePrefetch = true;
        ui32FlashConf &= ~(FLASH_CONF_FPFON);
        ui32FlashConf |= FLASH_CONF_FPFOFF;
        FLASH_CTRL->CONF = ui32FlashConf;
    }

However, MSP432E4 SimpleLink™ Microcontrollers Silicon Errata SLAZ709 – October 2017 doesn't list errata ETH#02.

Not sure if either:

  1. EMACMSP432E4.c doesn't need to apply the ETH#02 errata work-around, because the errata has been removed from the MSP432E devices.
  2. The errata exists in MSP432E devices, but has been omitted from the published list of errata.

    Hey Chester,

    I'm not sure so let me go look into this.   From my perspective, I think #2 is much more likely as my understanding was the Ethernet IP was borrowed from the TM4C. 

    Any harm in leaving the workaround in the driver for now while I try and confirm one way or another? 

    Thanks,

    JD

    I don't see any harm in leaving the workaround in the driver for now.

    Hey Chester,

    I haven't forgotten about this question, I'm still trying to get a confirmation on this one way or another.  

    Thank you for your patience during the summer holidays!

    Thanks,

    JD
