Hello all,
regarding the overdrive mode for the M7 Core described in the datasheet page 28 of the i.MX RT1176 I wanted to ask if there is a recommended way of booting the chip.
CONTEXT:
As for our BSP in our company we do this in a more inelegant manner initializing all the clocks including the core core in overdrive and after that then we do adapt the RUN-Mode-voltage for VDD_SOC_IN through an external PMIC. We did not observe any problems untilll now, but still I would like to ask again, what would be the official recommended way - if there is any - and if the way we do it does disturb somehow the further operation of the chip?
Thanks for helping me out!
Kind regards,
Isaac L. L. Yuki
Hi @illy777
Thanks for your question, it is confirmed that Overdrive mode is normal as shown in our datasheet, please note make sure external PMIC can works well during this period.
No any official way, actully it depends on different dedicated applications. If you want to consider the power consumption or use internal chip power , you need to make some optimizations.
B.R,
