DRA756: The problem of recognizing large USB storage devices in the RTOS SDK

Suyoung Yoon
Prodigy 10 points
Part Number: DRA756

Hi ALL,

I tested the DRA756 by connecting the USB storage device to the USB 3.0 port.

The SW environment configuration used for the test is as follows.
   -. RTOS SDK : pdk_dra7xx_1_0_10
   -. Example project : USB_HostMsc_evmDRA75x_armExampleProject
   -. Used USB Mass Storage :
          1) Sandisk UBS 3.0  64GB,
          2) Samsung USB3.1 1 TB SSD
  
In the case of the storage device 1, it is well recognized and both Read and Write operate well.
However, in the case of device 2, there is a problem with recognition.
 
When I checked the debug message by activating the debug mode of the USB driver,
there seems to be a problem with write in the case of storage device 2.
Attach usb driver debug messages for two storage devices. Please help to recognize USB storage devices.
