I know this pin is used in QSPI even after disabling the QSPI I am unable to toggle the GPIO what is the reason.
And this the sane pin I'm using for I2C that's not working.

Hi Karthik,
The P0.22 is by default, as you mentioned, used for QSPI. In order to use them for other purposes, you need to cut SB15 and short SB25 as mentioned here:

Have you done this?
