LX2160ARDB - DPMAC17@rgmii-id link not up with 4.14 Early Access kernel

[tnguyen2]

Hello,

I am pretty new to NXP and I need your help.

The issue I have is with network interface DPMAC17@rgmii-id on my board LX2160ARDB when booting with NXP's linux kernel 4.14 Early Access branch.

The link on the interface 17 is not up after the kernel boots but the link on the interface 18 is up if I plug in a network cable.

Here is from the boot log:

I see the network interfaces and able to assign an IP address to it but I got ping failure when trying to ping to the address on a PC connected to the same network.

Here are the software I use:

- Kernel: 4.14-early-access branch. .config file is based on lsdk.config

- Device tree: from lx2160a-early-access-bsp0.5 flexbuild

- File system: my own file system

- DPL:  From onboard flash

U-boot environment variables:

bootcmd=setenv ethact DPMAC17@rgmii-id; dhcp 0xa0000000; fsl_mc apply dpl 0x20d00000; bootm 0xa0000000

I don't have this issue with other NXP's kernels (remotes/origin/github.qoriq-os/linux-4.9 and remotes/origin/github.qoriq-os/linux-4.14) The reason I choose 4.14-early-access is for the PCIe Gen4 endpoint.

I guess with the 4.14-early-access kernel that includes recent changes, I may need to have a new DPL for it. For the time being, I don't know what I should change to the DPL file (I extracted one from the onboard flash) and how I reflash the compiled DPL to the flash (I was not successful when trying to boot with an SD card or a USB stick unfortunately.)

Full /var/log/messages file attached for your reference.

Your help would be highly appreciated.

Best Regards,
Tuan

Hello Tuan Nguyen,

Please check whether this problem is caused your improper DPL file, please refer to the attached DPL image from lx2160ardb BSP 0.5 release.

You could deploy it with the following command under u-boot

=> tftp 0xa8000000 dpl-eth.19.dtb

=> fsl_mc apply dpl 0xa8000000

If you are using flexbuilder,please build DPL refer to the following.

$ flex-builder -c mc-utils -m lx2160ardb

Please get DPL source and images in build/firmware/mc-utils/config/lx2160a/RDB/

You could get the DPL source code from package mc-utils git address.

$ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/mc-utils -b LSDK-18.12

$ make -C config/

Get images in config/lx2160a/RDB/

Thanks,

Yiping

Hi Yiping,

It works great! Now I got the link up:
