- MJ 01:24 PM Software Development: RE: MitySOM-5CSX ethernet PHY errors prevent ethernet in Linux
- Hi
Thanks for that information - that was it!
U-Boot 'mii dump' command reports that the Dev Kit has a PHY ID of 3 but our board has a PHY ID of 2.
BUT ... it looks like the Dev Kit was designed for the PHY ID to be 2 but turned out...

- Seeing as u-boot works correctly and linux doesn't I believe this has to do with the PHY ID. u-boot will just probe all possible IDs on the MDIO interface until it finds one but unluckily linux requires you to specify it in the device tr...

- The device is the Microchip/Micrel KSZ9031RNX, which I believe is the same as the Dev Kit.
The MDIO pins are connected like the Dev Kit except that as recommended by Microchip there is a 1K MDIO pullup instead of 10K as on the Dev Kit.

- Sounds like reset is working properly.
Are the MDIO pins connected the same way as for the Dev Kit?
Have you updated the preloader for your FPGA build? - MJ 03:56 PM Software Development: RE: MitySOM-5CSX ethernet PHY errors prevent ethernet in Linux
- Hi Mike
I believe the PHY is the same as the dev board, but I'll need to confirm that.
The activity LED for the PHY flashes during U-Boot start-up and then once for every ping out from U-Boot.
During Linux start-up I think I see the...

- What PHY are you using?
This sounds a lot like the PHY is maybe getting held in reset. Do you have a GPIO connected to the PHY reset pin? Can you scope that pin?
When linux boots, if you connect a network connection to the port, ... - Hi,
We have a PCB based on the development kit, where we are using a MitySOM-5CSX-H6-4YA and boot from SD Card.
At start-up we get PHY errors under Linux that continually get output to the console and prevent the Ethernet port being us...

- Yes, I amusing ubuntu 16.04. I read the same thing, so thank you for your help.
- DV 04:36 PM Software Development: RE: Hob Cannot Build Your Image
- Hello,
What OS are you using to try to build yocto? I believe I saw that issue if I tried to use an OS newer than ubuntu 14.04 - Hello,
I am using utilizing the "build your own root file system" tutorial, and I am having problems with the yocto GUI Hob. I have added a n image of my problem below.
Thanks for your help

- Thank you for you help! The system compiled after adding i686 gcc too path. Have a great day and thanks for such a fast response.
- DV 08:36 PM Software Development: RE: Preloader & U-boot
- Hello,
I believe the error about not being able to find the arm compiler is because the post installation script for the SoC EDS needs to be run. This script can be found in your Quartus directory under embedded/ds-5/run_post_install_... - Hello,
I am at step 15 of the Building u-Boot and Preloader section. Make produces the results in the image below. Am I missing something? Thanks for you help.
