Can not update pin mux ?

[bianchi]

Hi Everyone,

I try to compile a cape but I can't change pinmux, does anyone have the same situation ?
It's already loaded on SLOT but not doing the job :
root@beaglebone:/lib/firmware# cat $SLOTS
 0: PF----  -1
 1: PF----  -1
 2: PF----  -1
 3: PF----  -1
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,cape-universal
 5: P-O-L-   1 Override Board Name,00A0,Override Manuf,EBB-GPIO-Example
root@beaglebone:/lib/firmware#
dmesg :

/{
       compatible = "ti,beaglebone", "ti,beaglebone-black";
       part-number = "EBB-GPIO-Example";
       version = "00A0";

       fragment@0 {
             target = <&am33xx_pinmux>;

             __overlay__ {
                  ebb_example: EBB_GPIO_Example {
                        pinctrl-single,pins = <

                                0x074 0x37  // P9_13 PINS$29 GPIO0_31 = 31 Input Mode7 pullup

                               /* OUTPUT  GPIO(mode7) 0x07 pulldown, 0x17 pullup, 0x?f no pullup/down */
                               /* INPUT   GPIO(mode7) 0x27 pulldown, 0x37 pullup, 0x?f no pullup/down */
                        >;
                  };
             };
       };

      


Thanks
