HI All,
I am trying to enable UART2 on beaglebone black.
I have made below changes in am335x-bone-common.dtsi file but I am not able
to see any prints related to UART2 in dmesg logs.
uart2_pins: uart2_pins {
pinctrl-single,pins = <
AM33XX_IOPAD(0x954, PIN_OUTPUT_PULLDOWN |
MUX_MODE1) /* spi0_d0.uart2_tx */
AM33XX_IOPAD(0x950, PIN_INPUT_PULLUP | MUX_MODE1)
/* spi0_sclk.uart2_rx */
>;
};
&uart2 {
pinctrl-names = "default";
pinctrl-0 = <&uart2_pins>;
compatible = "free-electrons, serial";
status = "okay";
};
I recompiled the dts file and generated new dtb, and loaded this dtb file.
but no luck.
when I grep for the uart's in dmesg log it showing only one uart
ubuntu@ubuntu-armhf:~$ dmesg | grep uart
[ 0.526979] omap_uart 44e09000.serial: no wakeirq for uart0
what could be issue.
Thanks & regards,
Madhu
