TEB0911 - real time clock (RTC) question/problem

<< < (2/3) > >>

JH:
Hello,
sorry for the late notice. I'm today only back from Easter vacation.

Regarding the RTC we are still checking. We have already been able to reproduce something, but are still looking for the cause.

Regarding USB.
Did you use USB2 or USB3 Stick?
Do you have the same behaviour with our our reference design?
Did you changed one time USB Stick? --> I have seen some problems but still recognized on the PC on most USB ports (not all).
Or it's this one: https://support.xilinx.com/s/article/72992?language=en_US
We are working on 21.2 update at the moment.

Hello,

Welcome JH :)

RTC >We wait your input

USB> We are using a USB-keyboard, USB-mouse... that works less than 50% of the time. and we have a NVME,  a displayport screen.
The NVME works 100% of the time.
The screen 99% of the time.
(we are using vivado 2019.2)

Once I have updated Vivaodo 2019.2 with AR72AA2. I rebuild a *.xsa file to create a new platform and then use the new FSBL + PMUFW for building linux? I do not clearly understand where this 'patch' will be apply. Linux kenel, rootfs both? As you see i never stop to be a beginer.

(Do you want me to open a new topic on the forum to let others be able to follow, in case they need?)

Best Regards,
M

Hi,

Short update (I've changed the text :-)):
we find the problem. It's an HW bug. Connection is wrong (I was too stupid at the beginning to compare the two schematics :-( )
We check if we can find a fix for this problem.  I'll get back to you as soon as we have something.

Can you try out our prebuilt binaries from the reference design?

Do you have the same problem there?

Yes of course with TEB0911-test_board-vivado_2019.2-build_12_20200603131549
1. We have this reference TEB0911-04-9BEX1MA and I used _create_linux_setup.sh with TEB0911-04-9BEX1FA
I hope it is ok.

2. TE::hw_build_design -export_prebuilt  and then TE::sw_run_vitis -all

3. SD card with  image.ub, Boot.bin, init.sh

4. I have the same equipment attached on the TEB0911 (nvme, displayport, FMC board) all same except that on usb port I have plugged only a mousse.

5 . turn on  verify  turn off
    I can see the same problem, sometime everythings is ok sometimes it is not
    I have attached 2 logs where one I have USB port working and one not working

Difference between 2 files ( as far as I can see):

Hi,

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.

Have you tried another USB stick?
What did you see when you type "lsusb" in both cases?
When it's not available and you unplug and plug your usb device again. will it be recognised or not?

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.
