How to set drive strength of parallel display port on i.MX6

[camz]

We are driving a display using the parallel0 display port of the i.MX6, but when we observe the signals on a scope, we see that there is some overdrive on the signals.  How can we adjust the drive strength of these IOs when configured as a parallel display port?

I have attempted to change the drive strength settings for these pins as GPIO, but it does not appear to have any effect (I'm guessing that this only applies when then are configured as ALT5/GPIO).

Cheers,

Camz.

Hi Martin

one can try to change pad settings DSE,SPEED,SRE,

they take effect in any iomux setting, not only for gpio.

Also one can try to add small series resistors.

Best regards

igor
