I’m not very sure it’s a good idea using an -rc1 version. I see 3 chances:
1) backport to previous versions(it would be a mess)
2) wait until v5.17 is released in 7 weeks :-/
3) keep as is while someone else gives his Tested-by:
For example Ariel, that will also be one of the two maintainers of this board as I read below. And later bump uboot and Linux versions as soon as they are released.

This ^^^ wip name doesn’t sound that good to me. Ariel, is it possible to give a tag with a version like v0.1? So something shorter and more clear.

Have you given a go with latest Buildroot docker to check if uboot needs libfdtpy, python3 etc.? It’s highly probable it needs them.

Kind regards

uboot is there for a while. I have other board that get their uboot source from gitlab or other download point.
I think that we need to ensure a valid commit point. I should maybe force uboot to a specific one

Have you given a go with latest Buildroot docker to check if uboot needs libfdtpy, python3 etc.? It’s highly probable it needs them.

Suggestion, should be given to the other newest board that was added. I think that you are talking about
host-tools here. Please point me to this buildroot docker

I’m not very sure it’s a good idea using an -rc1 version. I see 3 chances:
1) backport to previous versions(it would be a mess)
2) wait until v5.17 is released in 7 weeks :-/
3) keep as is while someone else gives his Tested-by:

Well, only a few people can test it. I will wait Ariel

Ok

For example Ariel, that will also be one of the two maintainers of this board as I read below. And later bump uboot and Linux versions as soon as they are released.

uboot is there for a while. I have other board that get their uboot source from gitlab or other download point.
I think that we need to ensure a valid commit point. I should maybe force uboot to a specific one

+How to build it
+===============
+
+Configure buildroot:
+
+  $ make bsh_smms2pro_defconfig
+
+Change settings to fit your needs (optional):
+
+  $ make menuconfig
+
+Compile everything and buildr the rootfs image:
+
+  $ make
+
+
+Result of the build
+===================
+
+After building, the output/images directory contains:
+

+    ├── boot.scr
+    ├── ddr_fw.bin
+    ├── Image
+    ├── imx8-boot-sd.bin

+Flashing the emmc card image
+==========================
+
+To install the image on on eMMC
+
+  $ sudo uuu -b emmc_all output/images/flash.bin output/images/sdcard.img
+
+
+Preparing the board
+===================
+
+ * Connect a serial line to the board
+ * Power-up the board
+
+
+Booting the board
+=================
+
+By default the bootloader will search for the first valid image, starting
+with the internal eMMC.

This is not correct, sorry, I've just given a try and it builds correctly even if it fails with gitlab CI. You have to use this docker:
