Cannot seem to set GPIO on LX2160A

[userland]

Hi

I've been trying to write to the GPIO registers on the LX2160A through Trace32, right out of reset.

I can change the GPDIR registers, but whenever I try to change any GPDAT that, has been set as Output, nothing happens.

GPIO4 configuration

Here's how the GPIO4 base registers looks like (the only thing I've touched is Pin16 in GPDIR)

How do I make it work?

Please configure RCW[EC1_PMUX], RCW[EC2_PMUX], RCW[USB_EXT_PMUX], RCW[GTX_CLK_PMUX], RCW[SDHC1_DS_PMUX] as "0b01" to configure pin configuration as GPIO_4.

@yipingwangdoes NXP support a uboot update that enables GPIO?
