Hello NXP,

what is the procedure to take the kernel dump, memory dump and crash dump for any crash or segmentation fault in LSDK1906 on LS2088 .

If any kernel config has to be enabled please share the steps.

As i am also getting the below error on LS2088 inconsistency (eth0/dpmac.1 and eth2/dpmac.2) which is used as 10G ports.

root@localhost:/usr/local/dpdk/dpaa2# ./dynamic_dpl.sh dpmac.2 dpmac.1

parent - dprc.1

Creating Non nested DPRC

NEW DPRCs

dprc.1

  dprc.2

Using board type as 2088

Using High Performance Buffers

              ERROR: unable to create dpmac.1

./destroy_dynamic_dpl.sh: line 13: echo: write error: No such device

regards,

ranga

Hello ranga,

Kdump uses kexec to quickly boot to a dump-capture kernel
whenever a dump of the system kernel's memory needs to be taken(for example, when the
system panics).  The system kernel's memory image is preserved across the reboot and
is accessible to the dump-capture kernel.

Below is a link for the Kdump feature and how to enable it within the kernel:
http://www.kernel.org/doc/Documentation/kdump/kdump.txt

Below is a list of required packages that must be installed on the system for Kdump to work.  Please note that your kernel must be compiled properly for these packages to work as expected.
Kdump          
Kexec-tools
Kernel-debuginfo * 


Thanks,

Yiping
