Cannot see GPIO registers in MCUXpresso IDE

Hi, trying to debug project on LPCXpresso54608 Dev. board (LPC54608J512ET180 MCU from NXP) and cannot see GPIO registers. I want to see the content of all the ports and pins of GPIO, but in the "Registers view" I see only Registers r0 - r12, sp, lr. pc and so on... (see the pictures). Cannot see GPIO here.


I see GPIO only in "Peripherals", but when I try to check this option here I get always "Remote communications error" and then "No registers found for GPIO". Then MCUXpresso IDE stops working and doesn't see target anymore. I need to reconnect dev.board again and restart MCUXpresso.

All other options under "Peripherals" are working - e.g. "ADC", "LCD" and "IOCON".


How can I see the content of GPIO registers in MCUXpresso?
