Hi:
    I have change u-boot-fslc from branch "patches-2014.01" to
"patches-2014.07" this week.

    I notice that gpio_get_value( ) always return 0, no matter I set the
bit 0 or 1.

    when I test gpio by adding #define CONFIG_CMD_GPIO in
uboot_src/include/configs/mx6sabresd.h
and using gpio toggle <gpio_pin> to toggle gpio for 3 ~ 4 times, it will
failed to change the gpio polarity.

    Does anyone have the same issue on i.mx6Q sabreSD board?

Wally
