[TC-0710] No ethernet interface on hardknott_5.10.72-2.2.0-stable #13

Closed dbeulen closed 2 years ago

When i compile with the hardknott_5.10.72-2.2.0-stable manifest ethernet does not work on the TC-0710 device. Upon boot it reports the following:


[  OK  ] Started Network Service.

TechNexion i.MX Release Distro 5.10-hardknott edm-imx6 ttymxc0

edm-imx6 login:

if followed this guide https://developer.technexion.com/docs/building-an-image-with-yocto but updated my local.conf with these values as the sh file did not enter these values right in the configuration:

BASE_BOARD ?= "tc0700"
DISPLAY_INFO ?= "lvds7"

Full configuration file: local.conf.txt

If i plug in a cable i notice the green led blinking, orange led is off. On the default software the device worked, so it is not a hardware issue.

@dbeulen

Thanks for the feedback !

I apologize for any inconvenience caused. It's my fault. I neglect to update u-boot to latest version in meta-tn-imx-bsp. To enable ethernet on TC0700, it should include the patch as follow: https://github.com/TechNexion/u-boot-tn-imx/commit/8ae87966db41a82cdc51b3f72cb693d63de166ea

I just update u-boot/kernel recipe in meta-tn-imx-bsp to point to latest u-boot and kernel. https://github.com/TechNexion/meta-tn-imx-bsp/commit/5934a6ac33e3b18c3baaddad1d395346351301f3

Could you give it a try to fetch hardknott_5.10.72-2.2.0-next instead of hardknott_5.10.72-2.2.0-stable?

$: repo init -u https://github.com/TechNexion/tn-imx-yocto-manifest.git -b hardknott_5.10.y-next -m imx-5.10.72-2.2.0.xml $: repo sync -j8

BR,

Richard

Hello Richard,

I can confirm Ethernet works on the hardknott_5.10.72-2.2.0-next branch.

Thank you for your help.
