S32G2 Run the application on S32G-VNP-RDB2 ERROR

I strictly follow "AN13750" for operation, and the software versions are also the same. When executing to the position shown in the figure below, an error occurred:

hi,lion_6

Thank you for your information.

Which version of BSP/LLCE/RTD are you using? are you using RDB2 or RDB3?

Joey

Hi:
Thank you for your reply！

All of my software versions are the same as those in AN13750.

I am referring to IPCF kernel panic - NXP Community Disable DCach and Clear SRAM. There will be no kernel crashes, but new issues will arise:

hi，lion_6

Thank you for your information.

Have you replaced the kernel Image yet? This situation may occur if the kernel for compiling IPCF is different from the Kernel version used.
