Hi everyone,
I am using custom imx6ul board. I installed linux ptp and make change on "fec_ptp.c" . And also I made changes on dts file to get pps out but ı couldn't get pps out . Can someone help me.
Here my dts file :
"""
pps {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pps>;
gpios = <&gpio3 2 GPIO_ACTIVE_HIGH>;
echo-gpios = <&gpio3 8 GPIO_ACTIVE_HIGH>;
echo-active-ms = <200>;
compatible = "pps-gpio";
status = "okay";
};
pinctrl_pps: ppsgrp {
fsl,pins = <
MX6UL_PAD_LCD_DATA05__ENET2_1588_EVENT2_OUT 0x000010B0
MX6UL_PAD_LCD_HSYNC__GPIO3_IO02 0x000010B0
>;
};
"""
Here my config file:
""""
CONFIG_PPS=y
CONFIG_PPS_DEBUG=y
#
# PPS clients support
#
# CONFIG_PPS_CLIENT_KTIMER is not set
CONFIG_PPS_CLIENT_LDISC=y
CONFIG_PPS_CLIENT_GPIO=y
#
# PPS generators support
#
#
# PTP clock support
#
CONFIG_PTP_1588_CLOCK=y
""""
Here my fec_ptp.c :
"""
val = readl(fep->hwp + FEC_TCSR(fep->pps_channel));
val |= (1 << FEC_T_TF_OFFSET | 1 << FEC_T_TIE_OFFSET);
val &= ~(1 << FEC_T_TDRE_OFFSET);
val &= ~(FEC_T_TMODE_MASK);
val |= (FEC_TMODE_TOOGLE << FEC_T_TMODE_OFFSET);
"""
Thanks in advance!
