Beware of electronics engineers programming <--- LOL
I read on the lists about not being able to load the audio cape dtbo on
4.1.14-bone-rt-r17
I disabled the onboard HDMI in Uboot
I tried with failure just to see if the audio cape will load

I have a project that will eventually use the mcasp0 and am trying to
write an overlay to set all pins
so i figured i would try to set the mcasp0 pins and it fails
I also have a tough time just setting random GPIO pins which i cant
quite figure out
so far i can get the UART1, UART4, UART5 and I2C1 loaded correctly from
one file
now its just GPIO pins and the mcasp0
this is the snippit of the gpio stuff that dont work, rest of file below
removed for clarity
mygpio0_pins_default: mygpio0_pins_default {
pinctrl-single,pins = <
0x150 ( PIN_INPUT | MUX_MODE7 ) /*
(A17) spi0_sclk.gpio0[2] */
0x154 ( PIN_INPUT | MUX_MODE7 ) /*
(B17) spi0_d0.gpio0[3] */
0x164 ( PIN_INPUT | MUX_MODE7 ) /*
(C18) eCAP0_in_PWM0_out.gpio0[7] */
0x20 ( PIN_INPUT | MUX_MODE7 ) /*
(U10) gpmc_ad8.gpio0[22] */
0x24 ( PIN_INPUT | MUX_MODE7 ) /*
(T10) gpmc_ad9.gpio0[23] */
0x28 ( PIN_INPUT | MUX_MODE7 ) /*
(T11) gpmc_ad10.gpio0[26] */
0x2c ( PIN_INPUT | MUX_MODE7 ) /*
(U12) gpmc_ad11.gpio0[27] */
>;
};
fragment@5 {
target = <&mygpio0>;
__overlay__ {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&mygpio0_pins_default>;
};
};
even with ALL the GPIO pins commented out the cape does not load even
though overlay compiles correctly
you would think that since no pins are being set the uarts and i2ci but
would be set.
any help would be appreciated
