imx8m-evk uboot cannot find USB disk

mileswang — Mon, 27 Aug 2018 09:26:50 GMT

Dear sir,

I inserted a usb-disk into iMX8M-EVK J903 (Receptacle, Upright 90°, Type A), but uboot cannot find any storage device. I tried several usb-disks and all have same problems. Does imx8m-evk uboot support usb-disks?

Thanks,

Miles

No, the Uboot of the i.MX8M EVK board Linux BSP does not support the USB mass storage device operation.

Have a great day,
Artur

Hi,

What does it mean? Can't we check USB pendrives in imx8m u-boot?
