USB1 HS with LPC540XX

[mb15]

Hello all,
I want to use the USB1 HS interface of the controller LPC54S005 on an own board.
I have copied SDK examples for USB of the development board LPC54018 and modified them accordingly.

In the file usb_device_config.h I set HS to 1 and FS to 0.

#define USB_DEVICE_CONFIG_LPCIP3511FS (0U)
#define USB_DEVICE_CONFIG_LPCIP3511HS (1U)

And in the void APPInit(void) function I set the speed to high.

s_cdcVcom.speed = USB_SPEED_HIGH;

The board reports as high speed USB on my PC, but it does not return a device descriptor. Under Linux with dmesg the following error message comes up:

[31059.292763] usb 1-5: USB disconnect, device number 71
[31062.726683] usb 1-5: new high-speed USB device number 72 using xhci_hcd

[31126.977266] usb 1-5: device not accepting address 75, error -62
[31126.977349] usb usb1-port5: unable to enumerate USB device

In the program code the function USB_DeviceCallback is called once, for the event kUSB_DeviceEventBusReset. After that no more callback is triggered.

I would be very grateful if someone could give me a hint what the problem could be. With the flashloader program I can change the firmware of my board via USB1. Therefore I think that the hardware is ok.

Best regards
Laura

Hi mb15 

LPC54S005 SDK includes USB device code. You don't need port it from  LPC54018 .

Please download LPC54S005 from 

https://mcuxpresso.nxp.com/en/select

For Device demo: to change USB0 to USB1, we only need to change file usb_device_config.h as:

/*! @brief LPC USB IP3511 FS instance count */

#define USB_DEVICE_CONFIG_LPCIP3511FS (0U)

/*! @brief LPC USB IP3511 HS instance count */

#define USB_DEVICE_CONFIG_LPCIP3511HS (1U)

This is enough.

Please test it with a LPC54S005 SDK demo code.

Thanks,

Jun Zhang

Hello Jun Zhang,

Thank you very much for your answer!

Unfortunately I didn't find a sample program for USB with SD card in the SDK of processor LPC54S005. I find this only in SDKs of development boards.
But I saw that in Peripheral Tool you can configure USB MSC Ram and get already a lot of USB code for processor LPC54S005. I tried to modify this code to access the SD card via MSC, which finally led to the error message again.

In another test, I simply changed the pins in the sample program for processor LPC54018 to match my board. The code also runs on my processor LPC54S005 and the example works

Thanks for the sharing.

Which LPC54018 SDK demo code do you use?

I am using the example: lpcxpresso54s018_dev_msc_disk_bm

Thanks!
