TUSB9261DEMO: TUSB9261 UAS on Linux

Jaime Ellen

On the latest firmware 1.60, UAS doesn’t seem to work on Linux; instead, the TUSB falls back to the dramatically slower BOT (~50Mbps).

I see there were some issues in the past with using UAS from Linux. Is there any news, here? If not, might it be possible to see the firmware sources previously posted on E2E, so we can perhaps figure out what the issue might be?

In any case, thank you for your time!

Hi Jamie,

There have not been any changes made to the firmware recently to improve UAS functionality with Linux. However, I believe our firmware comes with UAS disabled, per this previous E2E: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1105428/tusb9261-recompilation-of-the-source-code?tisearch=e2e-sitesearch&keymatch=TUSB9261%25252525252520AND%25252525252520UAS#

Currently, we provide out firmware as-is and cannot support any software development needs. If needed, I can help to provide files needed on your end.

Thanks,

Ryan
