Hi Pramod

such exceptions can be due to memory errors, one can run ddr test and

rebuild image.

https://community.nxp.com/docs/DOC-340179 

Also please check that you did not copied some binaries from previous builds

or other kernel revisions. Recommended fully rebuild image with modified sources.

Best regards

Dear igor ,

It is on fresh image I have build as on yocto document .

* For ddr test suggest me how to go for ddr test.
