Other Parts Discussed in Thread: CDCE913,
Hello,
1. Customer used AM3359 dual MAC: RGMII and RMII。CDCE913 provides 50MHz to RMII, but the minimum fvco of cdce913 is 80MHz, how to configure it to output 50MHz。
2. Connnecting RMII clock to CLKOUT2 pin, the source of CLKOUT2 pin is l3_gclk, then divided by 4. How to configure the dts file to output clock from CLKOUT2?
SDK is the latest 06.03.
Modify the dts file:
&clkout2_div_ck {
clocks = <&l3_gclk>;
ti,dividers = <4>;
};
&am33xx_pinmux {
pinctrl-names = "default";
pinctrl-0 = <&clkout2_pin>; /* eth1时钟 */
clkout2_pin: pinmux_clkout2_pin {
pinctrl-single,pins = <
0x1b4 (PIN_OUTPUT_PULLDOWN | MUX_MODE3) /* xdma_event_intr1.clkout2 */
>;
};
But there is no output from CLKOUT2 pin.
Thanks.
Rgds
