LSDK 19.09 Network Problem

[carljones]

Hello,

I've migrated a running code from LSDK 18.03 to 19.09. The compilation has no errors but when the system boots up, the network interface seemed to malfunction. The dpaa2 object dpni seemed not bound to dpmac

Can you help me solve this problem?

Hello Carl Jones,

Please download LSDK 19.09 release from Layerscape SDK | NXP , then rebuild u-boot firmware and tiny images.

It seems that you are using the firmware image, I will generate firmware image with you DPL and DTS files, then do verification on the demo board.

Thanks,

Yiping

Hello yipingwang‌,

Thank you for responding.

As instructed, I downloaded the default LSDK 19.09 release, then rebuild u-boot firmware and tiny images. I loaded it to our LS1088A-RDB and tested the network interface ETH8 (dpmac.5) worked without problem.

However, my intention is to use ETH0, because the PHY behind it (AQR105) is the one we have in our custom board. So I tried to remove the dpni object using restool and created new one with dpmac.2 and tested the newly created network interface but it wasn't able to ping my target ip address.

Next, I tried to edit the DPL file and replace the default connection to dpmac@2, rebuild u-boot firmware and tiny images and reloaded it to our LS1088A-RDB.

/*****************************************************************
* Connections
*****************************************************************/
connections {
connection@2{
endpoint1 = "dpni@0";
endpoint2 = "dpmac@2";
};
};

The result was, I still cannot ping using ETH0.

Hello Carlos,

I have verified your procedure, dpmac.2 worked normally without any problem.

Would you please tried the attached dpl file and the pre-built firmware image which could be downloaded from the following link.

https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdrive.google.com%2Fopen%3Fid%3D1I1...

Please refer to the following to boot up the target board with modified DPL file.

=> tftp 0x80001000 b25805/ls1088ardb/dpl-eth.0x1D_0x0D.dtb

=> fsl_mc lazyapply dpl 0x80001000; run qspi_bootcm

Thanks,

Yiping

Hello Wang,

Thank you for verifying my procedure on your setup.

I couldn't load your pre-built firmware on our LS1088A RDB because ours is already in Secure Boot.

However, the procedure to manually load the DPL file prior to booting tiny linux solved my problem. I was able to load the user space images to the eMMC via network.

Thank you and keep up the good work.

Regards,

Carlos
