Hi Vinoth,

Do you found full solution for this issue?

I faced same... but i dont want to manually do mount via shell or native deamon.

Hi Tam Nguyen,

As per Bernhard solutions. Carrier board don't have the usb mass storage support. Only baseboard have the usb mass storage functionality.

Thanks & Regards,

VinothS,

I have base board here.. 

but when i connect usb to base board nothing detected?

What else i can do?

[bernhardfink]

But it should, I tested it with the baseboard and the USB Mini OTG plug.

Finally, it's just software. If in this NXP Android image version the other USB is not supported for connecting mass storage, then you could change this in the source code and make your own Android image.

Regards,

Bernhard.

Hi,

Verify the connection with carrier board and please use micro USB Converter to detect USB Mass Storage.

Best Regards,

Vinoth S.

On the i.MX 8QuadMax board from NXP there is only one USB brought out, this is the one you need for the Serial Download Protocol (Type-C connector). The second USB is not on there, but you get it when you have the baseboard. On this baseboard there is an USB Mini connector and with a converter you can connect a USB stick. And on this USB port Android can see a mass storage device.

Regards,

Bernhard.

Thank you Bernhard,

Is there any possible to make usb storage in that type c connector.

Because, I tested with Linux (Linux - 4.14.62) predefined images, it's working. 

Thanks & Regards,

Hi,

I fixed this problem temporarily,

If sda,

mount /dev/block/sda /mnt/media_rw/

mount -o rw,remount /

But, I needs to integrate with source instead of doing by manual.
