Other Parts Discussed in Thread: AM4372
Tool/software: Linux
Hi,
I am having custom board and i am using ti-processor-sdk-linux-rt-am437x-evm-04.02.00.09 . am437x-gp-evm.dtsour board has wlan (wg7831 module) connected over mmc3 interface and it requires slow clock to be enabled from the processor C24 pin XDMA_EVENT_INTR1 . In muxmode 3 it is configured as CLKOUT2 .
I have done following changes in my dts i,e. am437x-gp-evm.dts in kernel
&am43xx_pinmux {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&clkout2_pin &wlan_pins_default &gpio_pins &ddr3_vtt_toggle_default &unused_pins &debugss_pins>;
clkout2_pin: clkout_pin {
pinctrl-single,pins = <
AM4372_IOPAD(0xa74, PIN_OUTPUT_PULLUP | MUX_MODE3) /* xdma_event_intr1.gpio5_6 CLKOUT2 */
>;
};
after this changes i don't see any clock generated from the processor.please let me know if i am missing any configuration in kernel or should i enable this clock in u-boot to enable 32khz clock on that pin.
Regards,
vimal
