i.mx6 Quad Core intermittent boot issue

Hi,

Hello All,

We have built custom hardware with i.mx6 quad core processor and MMPF0100F0AEP as PMIC.

we have built 500 boards and we are observing the same issue in 100 boards.

We have also done similar trials on our hardware and still the same issue exists.

What is the solutions for this? It is very urgent.

Regards,

Srinidhi jois

Hi Jois,

We are aware of a boot up issues on the MMPF0100 on revisions Pass1.0 through Pass1.2, typically if power is removed from the board and reapplied within ~ 2 minutes. On MMPF0100 revision Pass2.0 this issue was corrected. For more details, see the PMPF0100 ERRATA, Issue #ER19: http://cache.freescale.com/files/analog/doc/errata/MMPF0100ER.pdf

Just make sure that you have a new revision of the MMPF100 or you would need the workaround mentioned in the errata document.

This boot-up issue can also be related to the POR configuration, try to extend the POR to meet the RTC_XTAL stability as mentioned in this community thread: https://community.nxp.com/thread/382025

I hope this helps.

Have a great day,
Jose
