TEB0911 - real time clock (RTC) question/problem

Hello,


--- Quote ---use prebuilt binaries without "2. TE::hw_build_design -export_prebuilt  and then TE::sw_run_vitis -all"
This will overwrite prebuilt binaries.
Download reference design again and use the pre generated files from the prebuilt folder " TEB0911-04-9BEX1FA" is OK it's only other emmc.
It probably won't make a difference, but I like to play it safe.

Done!

1. I have boot the TEB0911 without something connected to the USB
2. login
3. lsusb
4. plug
5.lsusb

I have the same behavior (attached logs)



--- Quote ---Have you tried another USB stick?

I have different usb devices and none of them works when it does not.
If It works everything works.


--- Quote ---What did you see when you type "lsusb" in both cases?

lsusb when it works

lsusb when it does not works

--- Quote ---When it's not available and you unplug and plug your usb device again. will it be recognised or not?

--- End quote ---
No, I tried. When it does not work, unplud/plug will not change something.


--- Quote ---Can you send me the serial number (the number on the small sticker with QR code) of your TEB0911 to "support@trenz-electronic.de".
USB should work , I would like to have a look at the test reports to see if I notice anything.

Done!
