Hi,

 

I built Linux image from bsp24.0, fsl-image-base, the ddr settings were generated from S32DS tools. I saw Linux kernel panic during boot up late stage. It did not happen every time, hit this every 10-20 times power cycles. U-boot, dtb, kernel and rootfs are flashed into emmc. Please advise. The full log file is also attached.
