Depending on which virtual/bootloader is selected could change the names and paths of these functions. (mainline vs ti-u-boot-2024.04) We can move all the scripts here in uEnv (or in the script node inside the fitImage for SE boards) or stuff them all in U-Boot but adding a hard dependency between the like this will be unfun to support. > Signed-off-by: Moteen Shah <m-shah@ti.com> > --- > .../recipes-tisdk/tisdk-uenv/tisdk-uenv/uEnv.txt | 15 +++++++++++++++ > 1 file changed, 15 insertions(+) > > diff --git a/meta-arago-distro/recipes-tisdk/tisdk-uenv/tisdk-uenv/uEnv.txt b/meta-arago-distro/recipes-tisdk/tisdk-uenv/tisdk-uenv/uEnv.txt > index 0af0eef3..5ac61b34 100644 > --- a/meta-arago-distro/recipes-tisdk/tisdk-uenv/tisdk-uenv/uEnv.txt > +++ b/meta-arago-distro/recipes-tisdk/tisdk-uenv/tisdk-uenv/uEnv.txt > @@ -7,3 +7,18 @@ > # default on all newer U-Boot images.

Or is this assuming that there will always be an initramfs? Because that is a problem if it is required all the time in all cases for all platforms.

Additionally, this is being done in meta-arago, but the ti-core-initramfs is staged in meta-ti so that it is available for all distros. Is this something that should move to meta-ti? Are these settings really a distro thing? Or a BSP thing?

That leaves one line left, `name_initramfs`. How about just setting a sane default name in u-boot. We got away with something like this for K2 plats: https://github.com/u-boot/u-boot/blob/master/board/ti/ks2_evm/k2e_evm.env#L12 although I'd recommend a more generic filename.
