Hello all,
I have a question regarding SC_P_SCU_GPIO0_00, did someone try to use it as a LSIO_GPIO?
I tried to use it as following
SC_P_SCU_GPIO0_00_LSIO_GPIO2_IO03 0x06000060 /* WAKEUP_TRIG */
GPIO2_I03 {
gpio-export,name = "WAKEUP_GPIO";
gpio-export,direction_may_change = <0>;
gpio-export,input = <0>;
gpios = <&gpio2 3 0>;
};
it appears in sys/class/gpio but always reads low, I tried configuring it as output and drove it high but when I measured the voltage on the pin it was 0 V. I am trying to eliminate the possibility of this being a common problem that people faced with this particular pin. Did someone try to use it before and was successful in doing so?
Hi Ahmed
one can try settings as in fsl-imx8qxp-mek.dtsi pinctrl_hog: hoggrp MCLK_OUT0, "GPIORHB":
fsl-imx8qxp-mek.dtsi\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel
and use latest L4.14.98 with all patches
Best regards
igor
