3.10.53 PCIe & USB 3.0

[myungjukim]

Hi, All

I'd like to know how to set for PCIe & USB3.0 controller(use for USB Stroage, USB Audio, etc) on imx6dl. Controller is TI's TUSB7340.

I've set for above issue, but I can't get any message when insert or remove to usb storage.

Could you any advice to me why don't recognize usb ?

I think, as look dmesg(attached file), XHCI driver(?) not running. and shown below message.

Hi Chrisitian

this may be due to ERR005723

Best regards

Hi, igor

hmm, Your information's means.. It don't support hot plug and power management, current and future.

and then, Is it possible as below scheme ? Could you tell me possible scheme for example ?

<pcie> - <usb controller> - <wifi> : static connection(always connected with boot, is not plug)

<pcie> - <usb controller> - <enet>: static connection(always connected with boot, is not plug)

Best regards.

Hi, igor

I updated kernel version, v3.10.53 to v3.14.28. After update, recognize the usb3.0 device. but I met the strange output from console.

How to solve the issue. I'm wait your recommend.

Hi Christian,

I am also using TUSB7320 with imx6qp on custom board. I using 3.14.52 kernel. I am able to see usb controller with lspci command, but i am not able to view any devices connected to it. Have you done any changes to xHCI driver to make it work?

[igorpadykov]

Hi Chrisitian

seems device is not detected, suggest to try with other tested and verified

PCIe modules described on

i.MX6 “PHY link never came up”

patches on link

IMX PCIe port: link down! with atheros pcie

One can test PCIe detection in uboot, recommended latest version

uboot-imx-2015.04.

Regarding driver, seems Linux xHCI driver works well with it :

Hi, igor

Thanks your support.

I think, PCIe Controller and XHCI host controller load success well, but I can't get any message when I insert usb storage to USB3.0 port. Do I find what part start and look any possibility.

We consist 2 type usb(2.0 and 3.0) to our device.

Hi

   My situation is similar to yours, but IC is p720202. Have you solved your problem? Can you check the usb device?

[igorpadykov]

Hi Chrisitian

if device is detected, then higher linux usb drivers should provide support

for this module. Had you tried it on other computers ?

Also suggest to use more newer kernel (and probably 4.x) :

linux-2.6-imx.git - Freescale i.MX Linux Tree

Best regards
