S32K14X CSEC pram data fillling problem

[1113240626]

as demo(cesc_keyconfig) say:  

plaintext = 00112233445566778899aabbccddeeff
ciphertext = 69c4e0d86a7b0430d8cdb78070b4c55a

why data is  32bit reversed when filling in pram ?

link plaintext  = 0x00112233 0x44556677

ciphertext=0x69c4e0d8 0x6a7b0430.

Do you have any document to explain this ?

Hi@1113240626

You don't need to waste your time on this.

You can check how the API "CSEC_WriteCommandBytes()" fills the PRAM.

hello, thanks for your response.

in s32RM_rel14, like the picture below。

Is csec subsystem big endian?

[1113240626]

I saw PRAM description  that the pram interface is Big Endian in s32kRM_r9, and  pram interface is Little Endian in s32kRM_r14. what happened? The chip‘s design had been changed？or is s32kRM_r9  error?
