Hi Yocto-Community,
as the subject already says I've a problem with my kernel recipe after the "migration" from the Dylan to the Dora (10.0.1) branch.
I've tried the 10.0.1 release tag as well as the current dora master (50e9ccb2aff7b9f9dca4fda99a6832c60f64de3b).
The kernel recipe I'm using is derived from the skeleton:
DESCRIPTION = "Linux Kernel"
SECTION = "kernel"
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://COPYING;md5=d7810fab7487fb0aad327b76f1be7cd7"
inherit kernel
KSRC = "/home/leri/VCS/git/linux"
KBRANCH = "master"
SRC_URI = "git://${KSRC};protocol=file;branch=${KBRANCH};name=kernel;nocheckout=1"
SRCREV = "2014_03_07"
PR = "sd_15.2"
LINUX_VERSION = "${PV}"
LINUX_VERSION_EXTENSION = "-${PR}+${SRCREV}"
COMPATIBLE_MACHINE = "skidata-harmony|smartcpu"
KERNEL_IMAGETYPE = "uImage"
SRC_URI += "file://defconfig"
require recipes-kernel/linux/linux-yocto.inc
This recipe was working well with the Dylan branch and following changes:
-SRC_URI = "git://${KSRC};protocol=file;branch=${KBRANCH};name=kernel;nocheckout=1"
+SRC_URI = "git://${KSRC};protocol=file;branch=${KBRANCH};name=kernel"
+S = "${WORKDIR}/git"
When compiled with the dora branch the kernel hangs at "Starting kernel..." and doesn't start:
## Booting kernel from Legacy Image at 00000000 ...
Image Name: Linux-3.1.10-sd_15.2
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 3181616 Bytes = 3 MiB
Load Address: 00008000
Entry Point: 00008000
Verifying Checksum ... OK
Loading Kernel Image ... OK
OK
Starting kernel ...
I've already looked through the migration notes in the manual but I'm unable to find any hints...
Are there any ideas why the kernel doesn't start with the Dora branch?
Thank you for your help!
best regards,
Richard

We saw an issue recently on beaglebone that looked very like this. It
turned out the load address for the kernel was conflicting in memory
with the device tree binary.
It easily be something different but I thought I'd mention it.

Do you mean that the bootloader was loading the device tree binary into the load address of the kernel?

Do you have any idea how to further debug the problem?

The kernel was large enough it was overwriting the device tree data.

you don't mention anything about gcc, so assuming you are using the
'default' gcc for each release, dylan has 4.7, and dora has 4.8. On a
couple of ARM platforms, i have seen similar issue when using gcc-4.8
with old kernel (<v3.4).
the following linux kernel patches were used to fix the boot problem:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=455bd4c430b0c0a361f38e8658a0d6cb469942b5
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=418df63adac56841ef6b0f1fcf435bc64d4ed177
They should cleanly apply to v3.1 which you seem to be using.
cheers,
nico

Thank you very much Nico!
These two patches fixed the problem and the kernel is booting again :-)
Just for completeness: Yes, I'm using the "default" gcc version and the two patches applied cleanly to my 3.1 branch.
