FRDM-RW612 USB_DEVICE_STACK_NEXT support

Hi , 

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

  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

Thanks Daniel, I follow the issue. I was about to create a issue on git

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

Re: FRDM-RW612 USB_DEVICE_STACK_NEXT support

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,

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.

Re: FRDM-RW612 USB_DEVICE_STACK_NEXT support

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 
#include 

#include 

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    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,

What example are you testing?

Could you please share some reproduction steps?

Daniel.
