DV 07:12 PM Software Development: RE: Ethernet on MitySoM: Hi Jonas,
The CSEL switches shouldn't have an effect on the ethernet interface, they are more used during the early boot process.
It sounds to me like there is a hardware defect with the development kit. Someone will contact you v... Daniel Vincelette
JM 04:27 PM Software Development: RE: Ethernet on MitySoM: I also tried it at home now (with your image) and I can reproduce the same behavior. So it points directly towards the hardware. Are there some hardware configurations, which might affect the behavior, e.g. the CSEL switches?
Regards ... Jonas Mair
JM 03:24 PM Software Development: RE: Ethernet on MitySoM: Hi Dan,
my plan was to take the board home over the weekend to test out a different router, in the office i tested with 2 different cables and 2 different router plugs, which worked fine for 100Mbps at least (only confirmed it with ... Jonas Mair
DV 02:37 PM Software Development: RE: Ethernet on MitySoM: Hi Jonas,
Thank you for providing the serial numbers. I've double checked our production logs and that development kit did link up at 1Gbps speeds and was able to send and receive ethernet packets before shipping out.
Can you boot ... Daniel Vincelette
JM 08:41 AM Software Development: RE: Ethernet on MitySoM: Sure,
Baseboard: 1701 8998
SoM: 1803 5616
It's an 5CSX-H6-42A-RC Module

DV 07:57 PM Software Development: RE: Ethernet on MitySoM: Hi Jonas,
If you are also witnessing this issue with our stock SD card image then it sounds like there could be a hardware problem with dev kit. Could you provide me the serial number of both the SOM and baseboard?
The serial numbe... Daniel Vincelette
JM 04:59 PM Software Development: RE: Ethernet on MitySoM: Okay an update:
Skews are set correctly, I read them out with [[ https://github.com/wkz/phytool ]] and could confirm the values set in the device tree after kernel boot.
I measured the clock GTX_CLK, supplied from the MAC to the PHY.... Jonas Mair

JM 05:23 PM Software Development: RE: Ethernet on MitySoM: Hey Dan,
I tried the device tree configurations you mentioned and also the generic ones adapted to my hardware from
https://elixir.bootlin.com/linux/v5.8.18/source/Documentation/devicetree/bindings/net
(also your example is listed th... Jonas Mair

DV 07:08 PM Software Development: RE: Ethernet on MitySoM: Hi Jonas,
Looking at the device-tree binding doc for the phy it looks like if you specify the phy address you need to put the skews in their own phy node instead of in the MAC node. Take a look at the example here: https://support.cri... Daniel Vincelette
JM 10:05 AM Software Development: RE: Ethernet on MitySoM: Hey Dan,
I checked the kernel configuration in menuconfig and directly in the .config of my kernel and the config was enabled.
Also it seems like the device is detected properly and the correct driver is chosen: Jonas Mair

TR 09:19 PM Software Development: RE: USB OTG - FTDI Device problems: Hi Dan,
Thanks for the feedback. That got it working!
Travis Rawson

DV 03:15 PM Software Development: RE: Ethernet on MitySoM: Hi Jonas,
You might not have the phy driver built into your kernel, so the phy skews aren't being set. I believe the config is: CONFIG_MICREL_PHY.
Dan Daniel Vincelette
JM 09:29 AM Software Development: RE: Ethernet on MitySoM: I apparently used the wrong gpio port, now the reset seems to be working correctly (ethtool shows a PHYAD of 3), but unfortunately i still can't get a higher speed than 10Mbs with sometimes high packet losses.
Jonas Jonas Mair

JM 12:01 PM Software Development: RE: Ethernet on MitySoM: Hey Dan,
thanks for the reply.
I created my dts with the sopc2dts tool, but appended the information given in your example, which currently does not seem to help.
Before that i already got it running roughly by calling ethtool -... Jonas Mair

DV 08:21 PM Software Development: RE: USB OTG - FTDI Device problems: Hi Travis,
I don't believe the reference project's kernel has built in support for FTDI serial devices. Looking through the kernel I believe you would need to rebuild the kernel with the following support: USB_SERIAL_FTDI_SIO, USB_SER... Daniel Vincelette
TR 07:54 PM Software Development: USB OTG - FTDI Device problems: Hello,
I am trying to connect a USB-to-RS232 dongle to the USB-OTG port on the MitySOM-5CSE-L2-3Y8 development kit with the reference sd card image running. Using dmesg results in the following:

DV 05:59 PM Software Development: RE: Ethernet on MitySoM: Hi Jonas,
From looking at your boot log it looks like the kernel incorrectly found a PHY at address 31, where it should of found it at address 3. This could be caused by the kernel or u-boot not taking the PHY out of reset.
In our... Daniel Vincelette

JM 02:17 PM Software Development: Ethernet on MitySoM: Hello,
I have a MitySoM Module and the accompanying dev kit.
To use ssh and scp, i wanted to enable ethernet. For that I configured a static ip address but no connection is established.
Has someone an idea, what else should be con... Jonas Mair
