How to enable USB 3.0 in LS2085A QDS Board..?

[anandhakumarm]

Hi all,

I'm using LS2085A QDS Board for development, in this USB 3.0 port is there, but that is not getting detected when i insert a pendrive in that.. I checked that in u-boot as well as in kernel. I checked with all the usb commands available in u-boot and also checked the dmesg in kernel.. inserted and removed the pendrive continuously but there is no entries in dmesg.. Please help me to make it working..

Hello Anandha Kumar M,

USB 3.0 is supported since 20150515 release.

There are two USB ports on LS2085QDS, please use USB1 to do USB 3.0 verification.

About RCW, please refer to field RCW[USB] and RCW[USB3_CLK_FSEL], the default RCW provided in the SDK ISO is fine.

The following is USB 3.0 test log in u-boot with SanDisk USB 3.0 storage device.

Hi Yiping,

Can u please provide the uboot image u have used for this usb testing ? so that i will also use the same uboot and test the same..

Thanks

Anandh..

[anandhakumarm]

Hi Yiping,

Actually we have the same settings in RCW[USB] and RCW[USB3_CLK_FSEL]. I didnt change that one, Anyway i will check one more time and update u..
