AM62L: AM62L - eMMC boot Fail issue

Jothi Mathi

Part Number: AM62L

Tool/software:

As per the Errata i2473 Boot: eMMC boot may fail, outlined in the “AM62Lx SitaraTm Processors Silicon Errata, Silicon Revision 1.0” document, the recommended workaround is to utilize eMMC boot via UDA.

In our SOM design, we support only the reduced pin count boot mode, where eMMC boot is limited to the MMC0 (eMMC) Boot Partition. While we have provisions for booting from a microSD card—which we are currently utilizing—eMMC boot support is mandatory for us. Currently, we do not have an option to enable eMMC boot using UDA.

We would like to confirm whether this erratum will be addressed in the next silicon revision and if eMMC boot using the boot partition will be supported in the reduced pin count mode.

Regards,
Jothi Mathi D

    Hi Jothi,
    Yes, the issue is fully rootcaused, and the fix is being implemented for next silicon revision.
    Yes, the eMMC boot from boot partition (once the issue is fixed) is supported via reduced boot pin configurations.
    Best,
