U-BOOT LED DRIVER

Hi Guys,
I want to control user led on u-boot source files. How can I control user led on u-boot board_late_init() function? Please advise. Simple led blink example code is enough for me.

Best regards

You can refer to u-boot/cmd/gpio.c and set the gpio of the led directly in the function.
