VJ 09:32 AM Software Development: RE: Second PHY MDIO interface

Dan, thanks for your feedback. Lesson learned: Always rebuild the preloader.
That fixed my MDIO issue.
Regarding the PHY mode: I am using a 100Mb PHY with RMII interface, and I don’t think my original scheme with the Splitter and RGMI... V J

SA 05:55 PM Software Development: RE: RGMII pad skew on KSZ9031

Thanks for the reply Mike. I'll talk to the software team and see if VxWorks resets the PHY. If not, then we will try the script route. If it does, we'll talk more later.

MW 11:22 AM Software Development: RE: RGMII pad skew on KSZ9031

Are you using uBoot to boot VxWorks?
I don't think there is enough space in the preloader to include the MDIO driver code and configure the RGMII, but I haven't ever tried that.
Updating the uBoot code should be pretty simple to ad... Michael Williamson

DV 04:10 PM Software Development: RE: Second PHY MDIO interface

Hi Vidar,
It looks like you are using Critical Link's 4.9 branch, is that correct?
Have you rebuilt and updated your preloader since enabling EMAC0? Seeing as you saw TX data out of the MDIO interface I'm assuming you have but I'm ... Daniel Vincelette

VJ 02:36 PM Software Development: Second PHY MDIO interface

Hi
I have added a second PHY to my board and connected it through the FPGA IO. I am using HPS EMAC0 and have added the emac splitter and the gmii_to_rgmii adapter in QSYS.
My problem is the MDIO interface. Connecting SignalTap to the... V J

SA 09:55 PM Software Development: RGMII pad skew on KSZ9031

We've got a custom board which is based on CriticalLink's baseboard. The PHY is the 9031. Try as we might to maintain the integrity of the RGMII signals on the PCB it seems the only way to get Gigabit working is to tweak the pad skew reg... Shane Avery

MJ 01:35 PM Software Development: RE: MitySOM-5CSX read-only Linux

Thanks a lot Mike.
That does seem to setup the filesystem as read-only, and is quite a simple solution.

VJ 09:19 AM Software Development: Duplicated name warnings

Hi
After updating my dts/dtb file I have an issue with the device tree generation. When booting the board I get a lot of these messages: V J

Theses issues are related to the stmmac driver.
