TDA4VM: How to compile the k3-j721e-common-proc-board.dts file alone without any overlay dependencies

Hi Krishna,

Can you walk me through the build steps and commands you have used.

Regards,
Tanmay

Hello Tanmay,

I used the  make dtbs (exported the CROSS COMPILER) for building the dtbs.

Here the situation is,  I have a working k3-j721e-common-proc-board.dts file of  version as below

// SPDX-License-Identifier: GPL-2.0
/*
* Copyright (C) 2019 Texas Instruments Incorporated - https://www.ti.com/
*/

and I am trying to include the above file changes in the following k3-j721e-common-proc-board.dts file of version as below.

So May I know how can I integrate the changes to the newer to have a successful build of DTBs

Thank you,

Krishna

Hi Krishna,

These are comments right. What changes are you expecting here?

Are you backporting some newer SDK changes to your older SDK?

Hello Tanmay,

Yes you are right , thise are only comments from the DTS files.

I am using the nxp tja11xx ethernet phy driver.

I  compiled dts file and got the dtbs. but now when I issue ifconfig once the system boots up, I get the following. 

[root@localhost ~]# ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0

[root@localhost ~]#

and not able to make the ethernet interface up. Could you please suggest any trouble shooting points w.r.t dts files,ethernet phy,cpsw. in general?

Thank you,

Krishna

Hi Krishna,

Can you share the boot logs (kernel and u-boot) and the changes i device-tree you have done.

Is this with overlay or have you added the required changes to the common-proc-board dts file?

Hello Tanmay,

The issue got resolved internally.

Thank you,

Krishna
