Can't drive GPIOs

    Hi, 

    I've tried to drive GPIO_111 as explained in the documentation in user space and it works. 

    But I've tried to do the same for GPIO_0,7,15 and 2, but it is not working : 
    For 0,7 and 15, I put the value 1 with the GPIO as output but the pin voltage doesn't go to 1.8V. 
    For the GPIO_2, I cannot export it. 

    What should I modify in the BSP configuration to enable these GPIOS? 

    Thank's

    Can you please provide the pin numbers for the GPIOs you are trying to drive? Based on the DM3730 SOM-LV:

    GPIO_0 - TWL_nINT, used to signal interrupts from the PMIC, not available externally
    GPIO_2 - SYS_BOOT0, not available externally
    GPIO_7 - uP_UARTA_DTR
    GPIO_15- HSUSB1_D2, not available externally

    So I am unsure what you are trying to do.
