RT685 USB Host sample code checking.

Hi Sir

I try to check the USB Host (MSD) sample code @ NXP RT685 EVK

sample code : evkmimxrt685_host_msd_fatfs_freertos (SDK version : 2.11.1)

After download the code, and plug in USB Storage. (Check the log)

We know that the RT685 don't support OTG.

Hi @StephenYeh,

A couple considerations:

In hopes to identify why you get three messages of "host init done", does the RT freeze after this message and you manually reset the device? Or from a single run, you got the "host init done" three times?

Are you using the default hardware jumper settings for this example, as stated on the readme.pdf?

Could you please confirm if the the baremetal alternative works? Or also shows the same issue?

Are you certain the U-disk device you are using is working properly and is discoverable?

Thanks for the clarifications,
Edwin.
