J721S2XSOMXEVM: Pinmux: Unable to update pinmux configuration in Baremetal code running on R5F

Part Number: J721S2XSOMXEVM

Tool/software:

Hi,

I am trying to modiy the pinmux configuration of certain pins, but for some reason the configuration isn't effective.

For example I configure T26(GPIO0_12) using the following line in my program after board init(after default pinmux config)
HW_WR_REG32((0x0011C030), PIN_MODE(7) | ((PIN_INPUT_ENABLE) & (~PIN_PULL_DISABLE & ~PIN_PULL_DIRECTION)));
Now when I execute this program on R5F(main R5F) (mcu2_0 on J721S2), and see the Registers, even after execution on above line, I still see the Pinmux configuration is still showing the default config.

Do I miss something, or do I need to do something else?

Thank you.

Best,
Moses
