[Buildroot] buildroot 2019.11.1 rpi-0-w error

[Buildroot] buildroot 2019.11.1 rpi-0-w error

[Laurentiu-Cristian Duca]

Hi,

  I am facing the following error in buildroot 2019.11.1
when configuring buildroot for rpi-0-w
with this settings:

make menuconfig
Kernel
    Defconfig name (bcm2835)
    In-tree Device Tree Source file names (bcm2835-rpi-zero-w)

make
>>>   Executing post-image script board/raspberrypi0w/post-image.sh

failed: No such file or directory
ERROR: vfat(boot.vfat): could not setup bcm2708-rpi-zero-w.dtb

  If I rename bcm2835-rpi-zero-w.dtb to bcm2708-rpi-zero-w.dtb in output/images,
the build succeeds but linux does not boot.

  Any ideas?

Thanks

According to configs/raspberrypi0w_defconfig the DTS name should
be 'bcm2708-rpi-zero-w' (or 'bcm2708-rpi-0-w' prior to [1], [2])
and the defconfig name should be 'bcmrpi'?

Does the plain raspberrypi0w_defconfig work for you?

Which linux kernel do you use (in doubt send your .config or defconfig file)?

Regards,
Peter

  Yes, it works. But only works with rpi linux.
I wanted to use linux mainline kernel compiled separately
and that is why I tried to use
bcm2835-rpi-zero-w.dts because mainline kernel does not have bcm2708...dts

Thanks

Then do not forget to change board/raspberrypi/genimage-raspberrypi0w.cfg:

--- a/board/raspberrypi/genimage-raspberrypi0w.cfg
+++ b/board/raspberrypi/genimage-raspberrypi0w.cfg
@@ -1,7 +1,7 @@
 image boot.vfat {
   vfat {
     files = {
-      "bcm2708-rpi-zero-w.dtb",
+      "bcm2835-rpi-zero-w.dtb",
       "rpi-firmware/bootcode.bin",
       "rpi-firmware/cmdline.txt",
       "rpi-firmware/config.txt",

And according to [3], [4] you need to add kernel and DTB file to /boot/config.txt,
e.g.:

kernel=zImage
device_tree=bcm2835-rpi-zero-w.dtb
