FRDM-RW612 USB_DEVICE_STACK_NEXT support

wima88 — Wed, 19 Mar 2025 20:54:13 GMT

Hi ,

I'm using zephyr 4.0.0 an tried to run some samples with USB device stack next an encounter following error

<err> usbd_core: Failed to init device driver

however I ran some samples with old usb device stack.

I would like to know if this is the expected behavior as of this zephyr version or am I missing something

Hi,

What example are you testing?

Could you please share some reproduction steps?

Regards,

Daniel.

Hi Daniel ,

Thank you for getting back to me .

I tried the following

1. use the hid-mouse example as it is with usbd_next_proj.conf

2. use with loopback class

1. proj.conf

CONFIG_LOG=y

CONFIG_USB_DEVICE_STACK_NEXT=y

CONFIG_USBD_LOOPBACK_CLASS=y

2. main.c

#include "sample_usbd.h" /*located on zephyrproject/zephyr/samples/subsys/usb/common*/ #include <zephyr/kernel.h> #include <zephyr/usb/usbd.h> #include <zephyr/logging/log.h> LOG_MODULE_REGISTER(app, LOG_LEVEL_DBG); static void msg_cb(struct usbd_context *const usbd_ctx, const struct usbd_msg *const msg) { LOG_INF("USBD message: %s", usbd_msg_type_string(msg->type)); if (usbd_can_detect_vbus(usbd_ctx)) { if (msg->type == USBD_MSG_VBUS_READY) { if (usbd_enable(usbd_ctx)) { LOG_ERR("Failed to enable device support"); } } if (msg->type == USBD_MSG_VBUS_REMOVED) { if (usbd_disable(usbd_ctx)) { LOG_ERR("Failed to disable device support"); } } } } int main(void) { struct usbd_context *sample_usbd; int ret; sample_usbd = sample_usbd_init_device(msg_cb); if (sample_usbd == NULL) { k_msleep(100); return 0; } if (!usbd_can_detect_vbus(sample_usbd)) { ret = usbd_enable(sample_usbd); { if (ret) { LOG_ERR("Failed to enable usb support !"); return ret; } } } return 0; }

in both cases I got <err> usbd_core: Failed to init device driver . to be little more specific -12(-ENOMEM)

after tracing the issue back I pin point the error to udc_mcux_init(...) function located in drivers/usb/udc/udc_mcux_ehci.c

to narrow it further

/* Init MCUX USB device driver. */ status = mcux_if->deviceInit(priv->controller_id, &priv->mcux_device, &(priv->mcux_device.controllerHandle)); if (status != kStatus_USB_Success) { return -ENOMEM; }

Hi,

If you use the HID mouse example as is, does it work?

Could you please try using Zephyr 4.1.0?

Is this custom code? If not, could you please point me where did you get it?

Regards,

Daniel.

Hi Daniel,

I tried it with zephyr 4.1.0,

still seen the same error code, according to 4.1.0 migration guide not much been change in zephyr USB side

If I use HID-mouse as it is USB stack is initializing properly and I can see device enumeration on host.

Hi,

I found the following issue in the Github repo NXP USB drivers don't work with usb_next · Issue #86409 · zephyrproject-rtos/zephyr. Looks like this has already been reported.

Could you please confirm is the same issue?

Regards,

Daniel
