PROCESSOR-SDK-J721E: basehash value changed - errors when building

Hi Randy,

Randy St. John said:

Then I was working on applying a patch and things would not build.  

What do you mean by this? Were you editing the sources while the build was happening?

Did you execute the commands recommended by bitbake? Can I see the results of those?

Best,
Jared

I was following guides and instructions to add a patch for a *.dtso file. I was not doing it while the build was happening. Matter of fact, I never got to editing the code because part of the steps to add a patch is to use "devtool" and the layer I was trying to patch "linux-ti-staging" would not suceed.

devtool modify linux-ti-staging

Hi Randy,

I see the devtool modify issue as well. Though, why are you trying to edit ti-linux-staging?

Best,
Jared

I want to edit a dtso file, or add my own as an overlay to mux out some different signals form the chip to the GESI board. We need I2C5 and some GPIOS to go to the GESI board that are not in the default build. We need to edit uEnv.txt to add the overlay as well.

I have just done it manually in the board_support directory but I was trying to learn how to apply a patch to the yocto build so in the future we could do stuff like this.

Is what we are doing unique? We are using the dev baord(s) to help us figure out what our custom HW will need to be and what interfaces and peripherals will work for us.

Hi Randy,

To add your own overlay, you could add a patch in your own custom meta-layer: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1303384/sk-am62-using-custom-kernel-in-local-workspace-for-yocto-ti-sdk/4953153#4953153

You can also look at the Yocto documentation: https://docs.yoctoproject.org/kernel-dev/common.html#using-devtool-to-patch-the-kernel 

To edit the uEnv.txt you would add a tisdk-uenv.bbappend, or modify tisdk-uenv.

Best,
Jared

Yes, all that is what I was trying to do when I got the errors. I was following creating my own meta-layer. But the patch in the layer has to know which recipe it is patching. In mine it seemed to point to ti-linux-staging to patch the k3-j721e-gesi-exp-board.dtso to add some GPIO muxing.

While doing all this is when I encountered the errors that prompted this forum question.

As an aside: I did try to patch the uEnv.txt with the bbappend method but I could not tell what recipie to patch that was applying the tisdk-uenv.bbappend file. In most of my Yocto experience the biggest difficulty I have had is trying to figure out which layers/recipies need to be modified.

Below is an example of a directory structure for adding patches to ti-linux-staging. The example is for the j721s2-evm and Linux 6.6, so you'll have change the MACHINE and version number, but it should translate.

The tisdk-uenv.bbappend edits the tisdk-uenv.bb recipe.

Jared,

That is helpful and is something I had tried before but without sucess. I will try again later. I am currently investigating some other things but will get back to it.

However, What can I do to get my kernel building again? Do I need to delete and start from scratch?

Hi Randy,

You can remove the workspace from the bblayers.conf

Best,
Jared

That worked. Any reason that was in there or any reason I will need to put it back in?
