iMX6DL Windows 10 IOT USB not detecting

inayathraza — Sat, 06 Feb 2021 05:48:13 GMT

We download the source code from the link

https://www.nxp.com/webapp/sps/download/license.jsp?colCode=W1809_1_1_0_imx-iotcore&appType=file1&DOWNLOAD_ID=null

and build the default FFU and Flashed it into SD and booted the imx6dl, But USB is not Detecting, we tried keyboard, as well as pen drives, But as per NXP Documentation USB host support, which is available in the BSP

Why we are not able to connect USB devices to the Board?

We tried with Default NXP images also we are facing the same issue with that images too

Hi inayathraza

reason may be that usb interface on custom board is not working. One

can check 24MHz crystal using IMX6DQ6SDLHDG, Hardware Development Guide for i.MX 6Quad, 6Dual, 6DualLite, 6Solo Families of Applications Processors

voltage on VDDUSB_CAP, try to perform usb test

Hi igor, Thanks for Reply

I am working on the IMX6DL sabresd board, Is there any way to enable USB, in Release Note its, mentioned as the USB stack is not enabled in
UEFI by default, How we can enable this in our FFU?

Hi Igor,

we are getting these log when we flashed default images from NXP website.

In the Same board when we are using Linux images USB host is working

We are using MCIMX6DL-SDP 700-27417 REV C SCH-27417 REV C4 Sabre_iMX6DL_1GB board,

the same board is mentioned in release notes

are you able to see below (from p.61 i.MX Windows 10 IoT Core User’s Guide)

for connection usb stick to usb otg, signal usb_id (pin4 J505 SPF-27417) should be low.

Hi Igor,

I am working with Inayath. In Linux Demo Image, USB Host is working fine for us but in Windows IOT image, its not working as it is. Logs for Windows IOT boot and Linux boot is attached in previous message.

In Windows IOT, LVDS display is getting up, but we are not able to get any relevant logs in debug port. Also USB Host and touch is not working means, we were not able to verify other drivers.

Hi m_syed_ahmed

had you tried to connect usb stick as suggested, with usb_id low.

Low level configures usb driver as host.

Hi Igor,

Thanks for your comments. Can I assume that by default, NXP image won't detect USB Host and we needs to modify in BSP to make USB host to work?

it is enabled by default, no need to modify BSP.

Hi Igor,

Thanks for your support. Our USB OTG cable was not functioning, we changed that and USB Host is working fine.

Additionally, I needs to know pin muxing for Windows IOT will only be done in UBoot or we needs to do the same in GPIO driver also.

Hello,

Can you share the way to enable debug over serial from uefi.fit?

Thanks in advance,
