Question about Yocto build multi BSP version

GG0712 — Mon, 28 Jul 2025 07:06:20 GMT

Hi NXP team,

For one code base folder with different BSP version

Does the Downloads, sstate-cache and build_s32g399ardb3 folders need to be separated?

My understand that Downloads can be the same, but I'm not sure it will have any risk if sstate-cache and build folder are the same.

If separation is required, is there any parameter in nxp-setup-alb.sh that can separate them during initialization?

Thanks

Hello, @GG0712

Thanks for your post.

1. Officially, it is suggested putting different BSP distributions to the different directory for use, since the situation you mentioned is not formally tested.

2. From my personal experience, in order for saving the size, you may use the same downloads directory, I did not test with the same sstate-cache before, but it is said from the Yocto wiki that:

You may test it and check if it is correct without issues.
