- JC 03:10 PM Software Development: RE: AM57x QT Starter Guide 2022 problem
- According to TI they only tested this release on Ubuntu 18.04. I've tested it on 20.04 and it works, but it doesn't work on 22.04+. I've updated the wiki to remove the reference to 22.04

- Thanks for letting us know. I'll run through the instructions and see if I can fix the steps needed.

- For additional information, I tried both in virtual machine and dual boot setup symptoms are same.
- I am just trying to follow QT Starter Guide 2022 step by step.
First I guess, there is no package called qt5-default in Ubuntu 22.04, So I installed qtbase5-dev, qtchooser,qt5-qmake, qtbase5-dev-tools by hand.
Additionally, standart ...

I don't know, I've never used an SFP in a design before. - SS 04:03 PM PCB Development: RE: Ethernet Connectivity issues with DP83822
- Hi,
Thank you for your prompt support.
Is there any modifications to be done in the kernel side for the fiber optic communication using SFP modules ?

- Hi,
The problem is solved now. We removed the 165 ohm resistance connected in the TDP,TDM, RDP and RDM lines. Now the ethernet connectivity is okay and ping also working.
Now we are facing another problem. We are planned for RJ45...

Did you also comment out or change the original MCASP2_AXR4 line. Just to make sure that pinmux isn't getting set twice.

I will verify the voltage levels on each lines.

If the phy link goes up and down, we can ignore the processor side of things. The phy itself handles establishing a link. ... - SS 04:36 PM PCB Development: RE: Ethernet Connectivity issues with DP83822
- Q: Do the link lights on the ethernet jack also go on and off?
Yes. Left side led of RJ45 is go on and off. When we connect to PC, the ethernet link is showing not connected.

- Hi,
We designed our own custom AM5728 board with two DP83822 PHYs. Desired phy address are phy0 and phy 1.
In the schematic shown , we removed R219 to make it to PHY 1. The other DP83822 has COL pin pull down with 2.2k resistance is...
