Accessible leds GPIO pin numbers on LS1046ARDB

Hello

Trying to control the accessible LEDs on LS1046ARDB via Linux userspace following this information:

 https://www.kernel.org/doc/Documentation/gpio/sysfs.txt 

I know that NXP SDK supports SYSFS possibility GPIO using  from userspace, and I've configured the kernel with COFIG_GPIO_SYSFS.

The issue is, that in order to actually control LEDs/GPIO, I need to know the pin numbers of the board GPIOs.

I did not manage to find any information about the board schematic or even GPIO pinout list.

Can someone help please?

By default (RCW from the NXP LSDK) there are no GPIO signals configured on the LS1046ARDB - refer to the U-Boot log and the QorIQ LS1046A Reference Manual, 3.4 Signal multiplexing details.
