i.MXRT102X BEE parameter update flow clarification

spthx — Wed, 26 Mar 2025 07:59:24 GMT

Hi,

I would like to use the BEE parameter update flow to update the software while using Encrypted XIP Boot on the i.MXRT102X.

For example, if the KIB of the image is
Key: 9e 6c e2 12 35 05 f0 f9 41 2b 9f 08 d2 d0 bc c5
IV : 59 f8 05 45 93 5c c6 8c 57 cc be e4 fa 5d c8 78

and if the start and end of the PRDB's encrypt_region_info are unchanged and the counter is
00 00 00 00 ff 68 db 33 96 5c c2 64 f3 03 73 d5,
how should the BEE register be set?

Should Key be set to BEE_AES_KEY_W0~W3?
And what should be set in BEE_AES_NONCE_W0~W3?

Best Regards,
