bareboxenv-target

bareboxenv-target

[Balasa, Bogdan]

Hi,

I'm using barebox 2014.11.0, kernel 3.14 on phyFlex imx6 and when loading barebox environment from userspace I get a wrong magic:
-------
./bareboxenv-target -l /mnt/bbox /dev/mtd1
envfs: wrong magic
-------
root@imx6q-pbab01:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00400000 00020000 "barebox"
mtd1: 00020000 00020000 "barebox-environment"
mtd2: 00800000 00020000 "kernel"
mtd3: 3f3e0000 00020000 "root"
mtd4: 01000000 00010000 "spi2.0"
-----

I have the barebox environment in NOR flash and I think is good since I can modify it and save it with the barebox menu.


Thank you,
Bogdan

This seems to be your Nand flash, so if you have your environment in NOR
FLash,

> mtd4: 01000000 00010000 "spi2.0"

it should be here. However, the NOR Flash is not partitioned, so the
partitions get lost somewhere between barebox and the kernel.

FTR: There's a pending meta-ptx fix here:
https://github.com/pengutronix/meta-ptx/pull/74

The solution for now seems to be to:

export TARGETCFLAGS="${TARGET_LDFLAGS}${HOST_CC_ARCH}${TOOLCHAIN_OPTIONS}"
export userccflags="${TARGETCFLAGS}"

It's yet unclear whether userccflags is meant to be used this way, but it works
for barebox.

Ahmad

Thanks for trying it out. Well, this is a general incompatibility of the SDK's environment
setup script with Kbuild then. I am wondering why they decided on not having a default
--sysroot. Raising the issue upstream could shed some light on this and perhaps result
in a fix. I don't think there is anything to fix here at the barebox side.

FTR: we use meta-ptx extensively and AFAIK we haven't run into this issue. It only
popped up when using the SDK build, so bitbake seems to do the right thing in that case.

Ahmad

Just ran into the same issue. Cause is as Roland describes the lack of --sysroot
as default and that it comes in via $CC, which Kbuild doesn't expect.

I guess this would break building kernel host tools too or how do they solve it?

I think someone more knowledgeable about Yocto/OE needs to answer this,
I don't know if anyone is here…

In barebox.inc of the Yocto recipe, I replaced
export TARGETCFLAGS="${TARGET_LDFLAGS}${HOST_CC_ARCH}${TOOLCHAIN_OPTIONS}"
with
export userccflags="${TARGET_LDFLAGS}${HOST_CC_ARCH}${TOOLCHAIN_OPTIONS}"

It builds.

Would that  be the way to pass sysroot to scripts/Makefile?

Renaud

We derived out recipe for barebox from the barebox layer.
We may have broken something in there.

The toolchain is built from our Yocto (dunfell-23.0.0)

Which toolchain were you using? IIRC, the Yocto SDK builds don't set a
valid SYSROOT during the build, and patch it in through a compile option
when calling the compiler.

bareboxenv-target

[Barbier, Renaud]

I am building bareboxenv-target for a  cortex-A9 board (not present upstream) with gcc 9.3.0 and got this error:

arm-oe-linux-gnueabi-gcc -Wp,-MMD,scripts/.bareboxenv-target.d -Wall -Wmissing-prototypes -Wstrict-prototypes -O2 -fomit-frame-pointer -std=gnu89  -I /mnt/projects/all/openware-core/home/renaud/sandbox/bootloader/barebox-rebase/scripts/include      -o scripts/bareboxenv-target scripts/bareboxenv-target.c
In file included from scripts/bareboxenv-target.c:1:
scripts/bareboxenv.c:17:10: fatal error: stdio.h: No such file or directory
   17 | #include <stdio.h>
      |          ^~~~~~~~~


It looks like sysroot is missing as when I add to scripts/Makefile:
ifdef SDKTARGETSYSROOT
    userccflags += --sysroot=$(SDKTARGETSYSROOT)
endif

It builds.

Not much came out from search on google but one thread that refers to this problem when building with Yocto.

Could it it be related to  how our toolchain got build?

Cheers,
Renaud
