TUSB7340: TUSB7340: TUSB73x0 SuperSpeed USB 3.0 xHCI Internal Host Error

zhaoming Ge

Part Number: TUSB7340

I met this same problem :https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1219898/tusb7340-tusb73x0-superspeed-usb-3-0-xhci-bulk-isochronous-error

Using a USB 3.0 protocol analyzer in between, for bulk transaction, when the issue happens, we captured lots of error. HOSTerr. and retry.

From https://www.ti.com/lit/ds/symlink/tusb7340.pdf?ts=1684093075880&ref_url=https%253A%252F%252Fwww.google.com%252F

I saw TUSB73x0 also provide 7.5.1.65 De-Emphasis and Swing Control Register. please check 7.5.1.65.

Do you have any tool to tune this De-Emphasis?

why HostErr happens, does TUSB73x0 provide any debugging register? thanks.

And Brian Zhou said it may be a linux driver problem, is there any deeper issues to dig into？ please help me.thank you very much.

This is the link talking about bulk transfer error in Linux Kernal driver.

Linux/TUSB3410: Bulk Transfer error with USB3.0 xHCI hosts - Interface forum - Interface - TI E2E support forums

We do have tool to change TX swing and De-emphasis with EEPROM.

Hi Brian

Thanks for your reply,i read the post but i think it's not the same issue which i met.

I run about a dozen cameras but have a camera jam problem about once every ten days or so, it's a single camera each time, and the camera that fails is random, and, not every time a camera jam occurs.

The data that the USB analyzer grabbed was from infineon cypress->TI usb controller->host.The problem always occurs while the camera is running, and at the time of the problem there is no control message, but a Host error error for the bulk packet, if you have an email I can send you the grabbed packet to look at, thanks. I would also like to ask what software should be used to open the uport11x0_usb3_ubuntu17_xhci.usb shared by CT on ubuntu, thanks.

Thanks & Regards,
