Keeping or Correctly Generating DTB Files

[xqdzn]

Hi, I have read this forum rules and guide and I think my questions should be posted in this section. Feel free to move it to the right section if I am mistaken.

I know my board is not officially supported by alarm project.
My board is Banana Pi P2 Zero and I followed this tutorial to build an image on sdcard. And used bananapi_m2_zero_defconfig as defconfig since the official said the board has almost exact same hardware.

It works with some bug:

- Ethernet not working
- WiFi not working
- HDMI not working

So I tried to extract and copy DTB files from this properly working ubuntu image and put it in /boot/dtbs directory with exact filename as it's already there before.

I booted normally.
Ethernet, WiFi, and HDMI working properly.
The problem is, the DTB files (/boot/dtbs/sun8i-h2-plus-bananapi-m2-zero.dtb) got replaced/recompiled everytime I do kernel upgrade using pacman -Syu
So here is my questions:
1. How can I config to make kernel-compiling-procedure to compile/generate DTB files properly?
2. Or, can I just tell the system to not-to reproducing/recompile/replace previous DTB files?

Thank you so much, guys.

update:
just some proof what happened after I do kernel upgrade over pacman

I tried to build new fresh image from latest ArchLinuxARM-armv7-latest.tar.gz
Boot it, then upgrade it.

Does Arch ARM even write out to /boot/dtbs? I believe /boot/overlays

[xqdzn]

Not sure, but it's always replaced with new one.
this could help, perhaps?

Well, for anyone who experienced same problem. The temporary fix for me is change u-boot configuration file so it would boot with dtb file outside /boot/dtbs.

[xqdzn]

To answer my own questions, this is why upgrading kernel rewrite DTB files.


excerpt of PKGBUILD:
$this->bbcode_second_pass_code('', '
mkdir -p "${pkgdir}"/{boot,usr/lib/modules}
make INSTALL_MOD_PATH="${pkgdir}/usr" modules_install
[b]make INSTALL_DTBS_PATH="${pkgdir}/boot/dtbs" dtbs_install[/b]
cp arch/$KARCH/boot/zImage "${pkgdir}/boot/zImage"

')

So in order to avoid it, you should modify the PKGBUILD file for kernel.
I think this thread should be closed.

I use a different boot.txt, so the dtb is located in a different directory, within the /boot directory.
The updates don't modify the boot.scr, so it's safe manner to address a different dtb.
This is mine
$this->bbcode_second_pass_code('', 'setenv rootcmd "LABEL=TB-MM-root"
setenv fdtfile rk3288-tinker-s.dtb
setenv bootargs "console=ttyS2,115200n8 root=${rootcmd} rw rootwait"

load ${devtype} ${devnum}:${bootpart} ${kernel_addr_r} /boot/zImage
load ${devtype} ${devnum}:${bootpart} ${fdt_addr_r} /boot/dtb/${fdtfile} ### dtb is my custom directory
fdt addr ${fdt_addr_r}
load ${devtype} ${devnum}:${bootpart} ${ramdisk_addr_r} /boot/initramfs-linux.img
bootz ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
')
Anyways you may set an environment variable on the first lines as I used with fdtfile and then modify that in order to avoid risk of messing sensible parts of the script.

Good to know. Thank you for the tips!

BTW, I'm used to delete all DTB that aren't related to my MCU.
I wonder if we may have a download-on-demand, rather to get 600 and over dtb.

To my mind the problem is that sun8i-h2-plus-bananapi-m2-zero.dtb is the device tree blob for bananapi-m2 when you have a banapi-p2, so me I'd change the name of the blob to something like sun8i-h2-plus-bananapi-p2-zero.dtb

You'll then need to direct uboot how to find that, yes if you have a modern uboot that uses /boot/boot.scr then you can add into boot.txt and recompile.

Thing is that mainline dts although they describe hardware, will slowly be updated as hardware is better understood. So do at times get updated. Don't think the p2 is yet in the kernel source, so it won't get updates ....
