Hi community,

 

I want to know how to stop I2C communication from i.MX6 to MMPF0100 after boot.
I know sometimes i.MX6 communicate with MMPF0100 by I2C automatically after boot.
However, rarely this communication cuase a problem on a custom board.
So we want to use I2C communication to MMPF0100 when only u-boot works for changing MMPF0100 output voltage.
In other words, we want to prevent I2C communication to MMPF0100 after Linux kernel is booted.
Could you let me know how to do it?

 

Best Regards,
Satoshi Shimoda
