Regarding multiplexed function of i.MX6UL

[surendrajadhav]

Hello,

i.MX6UL has got Booting options where 24 LCD lines are used. At the start up, state of these pins are polled to select the booting device. However out of these, first two pins I have to use for I2C function where I need pull up on these lines. So if I put pull up on these lines, it will lead to disturb the booting mode. However datasheet and pin mapping excel suggest I can use I2C as alternate function also. Let me know how to handle this.

One more query was I am using PMIC PF3000 for powering the i.MX6UL. Can you review my PMIC and processor connection in the attached image?

Regards,

Surendra

Hello,

1.

  I think, it is necessary to use other pins for I2C signals, if

pulling up of the affected BOOT_CFG signals influences on

boot parameters. Other option - use fuse configuration

for boot.

  You may create request to get schematic for i.MX6UL with PF3000 ;

Your pictures quality is difficult for consideration.
