IMX6UL One nano second delay

[balasubram]

Hi,

I have IMX6ul based custom board and i want to generate 1 nano second delay in kernel driver. I tried with ndelay(), hrtimer APIs  using gpio toggling but delay goes to microseconds? How can i proceed for this?  Is it possible use timer registers directly in my kernel driver? If so please provide samples.

Hi BALA

I am afraid it is not possible to use timer for such small delays, probably

one can try to add some nop operations in code.

Best regards
igor
