Hi,

I am using "evkbimxrt1050" for testing the USB host SDK example "usb_host_msd_fatfs".

But the example not works. Log info shows "host init done", after that now log. Also the Breakpoints are not hitting after USB insert.

Can anyone help on this.

Regards

Sudheer

Hello Sudheer,

 

I have tried to use the example you are referring to replicate this issue on my side. However, device was detected correctly when the USB was attached. Please check my test below.

I used usb_host_msd_fatfs_bm example from SDK 2.7.0 and MCUXpresso IDE v11.1.1. I ran the example on my MIMXRT1050-EVKB.

 

Best regards,

Felipe

Hi

Are you connecting the memory stick to the correct USB connector? The one furthest away from the Ethernet jack is used for host mode.

To test the HW load the attached binary file which gives USB-CDC device on the first USB device interface and USB-MSD host on the second. This is a standard uTasker configuration, fully encrypted with serial and OTA uploading support built in (see https://www.utasker.com/docs/iMX/uTaskerLoader_TestDrive.pdf for loading and other details) which will allows you to verify that the USB host issue it is not a local board problem.
Command line interface of the debugger's VCOM at 115kBaud or on the USB-CDC device connection:

Hi Felipe,

Thank you for your help, I was actualy trying on J10 connector. I changed the code to work for J10. Now it works fine.

In my cutom board we are using OTG2 (which is same as J10 in EVKB). The same code not working in my custom board. The only harware difference is, we are not using micro USB connector (the regular 4pin USB connector is used).

When I connect USB to board, I was getting "enumeration failed" error on the debug console.

Can you please help me.

Regards

Sudheer

Hi Sudheer,

 

I highly recommend you to check our i.MX RT Hardware Development Guide for the MIMXRT1050/MIMXRT1060 Processor. In this document you will find a chapter dedicated to USB that gives you guidelines that you may find useful and that you should check that you are following in your design. In addition, you can consult IMXRT1050 EVKB schematics for reference.

 

Best regards,

Felipe
