[Buildroot] [PATCH 1/2] board/beaglebone: fix boot on BeagleBone Black

[unixmania at gmail.com]

From: Carlos Santos <unixmania@gmail.com>

Commit 68b5b79b2f has set the getty port to the default console but left
"ttyO0" in bootargs, in the U-Boot environment. Use "ttyS0", instead.

Also set loadaddr to 0x82000000 and fdtaddr to 0x88000000, replacing the
ancient U-Boot 2013.10-dirty default values that cause system hangs.

Where are we using U-Boot 2013.10-dirty on BeagleBone ?

$ grep UBOOT_CUSTOM_VERSION_VALUE configs/beaglebone*
configs/beagleboneai_defconfig:BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2019.04"
configs/beaglebone_defconfig:BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2019.07"
configs/beaglebone_qt5_defconfig:BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2016.09.01"

And these are upstream, unpatched, versions.

Could you clarify this? Otherwise the patch looks good, of course.

Thanks!

Thomas

That's the SPL in old Beaglebone cards. I will rephrase the commit
message to clarify it.

[Buildroot] [PATCH 2/2] configs/beaglebone: use the new BeagleBoard/BeagleBone kernel repository

[unixmania at gmail.com]

From: Carlos Santos <unixmania@gmail.com>

The original source URL (http://beagleboard.org/source) now redirects to
https://elinux.org/Beagleboard:BeagleBoneBlack_Rebuilding_Software_Image
which points to an official kernel repository at GitHub.

There are updated RT and non-RT kernel source trees. Use the last non-RT
release (4.19.73-ti-r29) and the omap2plus defconfig.

I've applied to next... but after doing, I realized that you could have
used the github macro, like we do in beagleboneai_defconfig. Could you
send a patch for that ?

Also, it would be nice if we could align beagleboneai, beaglebone and
beaglebone_qt5 to use the same U-Boot/Linux versions, if possible. I
see that the beagleboneai is using 4.14 even though it's a much newer
platform than beaglebone.

Thanks!

Thomas

I kept using git download method but I can replace it by the download
or the tarbal from GitHub.

I have been working on it but did not have much free time in the last
weeks. I will try to fix it on time for 2019.11.

Yes, it's nicer to use the github macro, it saves a lot of download time.

Sure, no problem. That was really a "nice to have" comment. Thanks!
