Other Parts Discussed in Thread: TUSB1210
Tool/software: Linux
Hi,
We are using ulpi interface for usb3 and usb4. We have TUSB1210 phy chip.
We have configured the dra76-evm.dts as,
&omap_dwc3_3 { status = "okay"; /*extcon = <&extcon_usb3>;*/ }; &usb3 { dr_mode = "host"; snps,hsphy_interface = "ulpi"; status = "okay"; /*reset-gpios = <&gpio5 17 GPIO_ACTIVE_LOW>;*/ }; &omap_dwc3_4 { status = "okay"; /*extcon = <&extcon_usb4>;*/ snps,dis_u3_susphy_quirk; snps,dis_u2_susphy_quirk; }; &usb4 { dr_mode = "host"; snps,hsphy_interface = "ulpi"; status = "okay"; /*reset-gpios = <&gpio5 17 GPIO_ACTIVE_LOW>;*/
};
and we enabled the .config file for ULPI and after booting linux, on listing the ko modules it shows ulpi is loaded. The problem is the CPEN of the phy chip is not driving the power switch. Checked the clock as well which shows 60 MHz. We are using processor sdk linux automotive 5.01.
