Part Number: AM4376

Hello,
I am working on a project based on the AM4376 + RT Linux, we have our own custom hardware board,
we successfully ported Uboot and RT kernel, next i tried to control GPIO from user space (/sys/class/gpio), i can control most of all available/free GPIOs, but i am facing problem to control GPIO0[3] and GPIO0[27].
I checked the DTS file for the pin defination entry in any node, but no where it is defined.
Using the command line I checked gpio info and it is showing "sysfs" "output" but control actions (High,Low) not reflecting on GPIOs.
Please find the attached output of 'gpioinfo' command.
I also checked hardware by porting TI RTOS and using that I can configure and control GPIO0[3] and GPIO0[27], so I assumed that hardware is working.
Please suggest any other way to test it and make it fucntional...
Regards,
Piyush Ghatole
