iMX93 USB 2.0 device tree node undefined

AlanWen — Wed, 05 Jun 2024 09:13:46 GMT

I'm using the iMX93 EVK board porting USB 2.0 device tree, the original source code is porting fort type-C.
I'd tried to post the code below in u-boot dts (imx93-11x11-evk.dts) but it doesn't work.

reg_usb0_host_vbus: regulator-usb0-vbus { compatible = "regulator-fixed"; regulator-name = "usb0_host_vbus"; regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; enable-active-high; regulator-always-on; };

Also, I tried to modify the usb node for switching to host mode as below. It seems not a correct way to port USB as host.

&usbotg1 { dr_mode = "host"; status = "okay"; };

And then modifying the configuration in imx93-11x11_evk_defconfig.

# CONFIG_USB_TCPC is not set CONFIG_IMX_HAB=y

How can I modify the code for USB 2.0 ?
Could you please provide a complete sample code

Thanks

Hi,

Thank you for your interest in NXP Semiconductor products,

According to Reference Manual p. 90 you should make it with dr_mode change made. Could you try to remove the config:

[*] ChipIdea device controller

Or is this issue only persistent in u-boot?

Also, is your work over an EVK or custom board? i.MX 93 processor has USB 2.0 already,

Regards
