usb mass storage reading speed is low for xhci in u-boot

[andyzheng]

HI:

I tried to load linux image from usb mass storage in u-boot, but the speed of usb mass storage loading speed  is just about 1.7MB/s, it's too slow for me.

My u-boot version is 2016 Sep. My CPU is NXP LS1043 witch have 3 USB 3.0 interfaces.

Is there any way to up speed the usb mass storage reading speed ?

Thanks for your help!

U-boot drivers are not optimized for speed. Usually u-boot is used only for kernel, root file system and .dtb file loading.

NXP LSDK 1712 provides up to 300MBytes per second for data reading from USB memory stick under Linux.

Test your board using u-boot from this BSP.

Have a great day,
Pavel Chubakov
