Hello everyone,
System: sama5d3_xplained board
I have a question regarding the configuration and build of u-boot.
We have a build that was implemented earlier. I am trying to make
some changes to it.
Change 1: Change the auto boot delay to 1 second.
Change 2: Add an auto boot command to set a gpio.
I am aware of the environment variables: CONFIG_BOOTDELAY and CONFIG_BOOTCOMMAND
(needed for the changes above.)
I tried modifying the "
configs/sama5d3_xplained_nandflash_defconfig "
Question 1: Do I need to create an *.config file using the make
menuconfig?
Question 2: How do I create the u-boot.bin . Does this depend on
the Linux build?
I know that there is an environment variable:
CONFIG_BOOTARGS that needs to be populated.

I'm
working on this project with Pratham. Let me provide a few more
details.
We've defined
UBOOT_MACHINE ?= "sama5d3_xplained_nandflash_config"
Inside
u-boot-at91/sama5d3_xplained_nandflash_config
we change CONFIG_BOOTDELAY, but it has no effect on the newly
built image. The boot delay remains the same as it was before we
changed it.
Based on the UBOOT_MACHINE, can we be certain we are changing the
correct file?
How do we get the build process to include our changes?
Thanks,
David

Hi, I think it would be interesting information to know "how" you change the value inside "u-boot-at91/sama5d3_xplained_nandflash_config".
As every time you rebuild it may be redownloaded, you should do this via a patch to append to the recipe.
Are you doing this? Or just changing it locally?
If you give some more info probably we can better help!
Cheers, Federico

We
changed the file directly.
Since it's a custom file, I don't think it is being downloaded.
What is the easiest way to determine if it's being downloaded?
Thanks,
David

Hi David, If you change it directly, changes may not be taken into account for the rebuild. And if the package build gets retriggered, then the whole repository is deleted (including your local changes), redownloaded, repatched and so on. So while it may by chance work by modifying locally in certain conditions, it will most likely not.
I would see two ways: 1) Create a patch that does your changes and add it to the recipe (most likely now in a custom layer) as a patch 2) Fork the repository, add all your customizations there, and point the recipe (again most likely now in a custom layer) to that one.
Cheers, F.
