Hi all,
I'm using Intel ECI 3.0(Debian Distribution, LTS PREEMPT_RT kernel 5.10.115-rt67-intel-ese-standard-lts-rt+, Installed by using ECI deb packages),
and I would like to enable kernel crash dump to dump whatever is in RAM (memory) to disk when the execution of the Linux kernel is halted or crashed.
I checked the kernel config parameters and It seem that the LTS PREEMPT_RT kernel doesn't suport kernel crash dump:
# CONFIG_KEXEC is not set
# CONFIG_KEXEC_FILE is not set
# CONFIG_CRASH_DUMP is not set
So, I was wondering if you could give me some advice on how to active kernel crash dump on Intel ECI 3.0 ?
And in case I have to change the kernel config parameters for support kernel crash dump, please advise me how to change these parameters.
Best regards
BUI

Hi,
Please refer
https://eci.intel.com/docs/3.0.1/development/eci_build_engine.html
Step 4: Start a bitbake Environment
Please try the following
./setup.sh
KAS_CONTAINER_IMAGE=jammy-kas-isar:3.0.2 ./kas-container --git-credential-store ${HOME}/.git-credentials shell targets/kas/eci-packages-bullseye.yml
#add your kernel config
vi /work/targets/layers/meta-tgr/meta-eci-isar/recipes-kernel/linux/files/amd64_5.10_intel_defconfig
bitbake linux-intel-rt -c cleansstate && bitbake linux-intel-rt
exit
#obtain the deb package and install
build/eci-packages-bullseye/tmp/work/eci-bullseye-amd64/linux-intel-xenomai/5.10.140-4/linux-headers-intel-xenomai_5.10.140-bullseye-4_amd64.deb
build/eci-packages-bullseye/tmp/work/eci-bullseye-amd64/linux-intel-xenomai/5.10.140-4/linux-image-intel-xenomai_5.10.140-bullseye-4_amd64.deb

Hi BUI,
I've been looking through the ECI documentation and I'm not seeing anything related to enabling kdump. Let me reach out to the development team for additional assistance. I will let you know what I find out.
Regards,
Jesus
