Linux/AM3354: USB Mass Storage Gadget performance

Part Number: AM3354

Tool/software: Linux

Hi

I use the SDK version: SDK_RT_3.3 AM3354, I have a question about Mass Storage Gadget ask you about it.

The use of the environment are as follows:

SD card environment:

File system: FAT32 cluster size 4096 bytes (4K) SD card capacity of 128G

AM3354 environment

Single-core CPU clocked at: 1G DDR3L: 512M

Window 7 environment

Window 7 64bit cpu:2.8GHz DDR: 8G

Windows 7 using Cato SD card read and write speed test

read speed 20Mb/s write speed 16.8Mb/s

AM3354 USB2.0 made Mass Storage Gadget mode, re-read and write peripherals AM3354 SD test:

Power on AM3354.

Use the g_mass_storage module to use the AM3354 SD card as a PC peripheral.

modprobe g_mass_storage file=/dev/mmcblk0p1 removable=1 iSerialNumber=sn7890

Windows 7 using AM3354 MSG read and write speed test

What should I do to speed up MSG reading and writing?

Thanks
