Compiler/MSP432P401R: AES256 CBC

Part Number: MSP432P401R

Tool/software: TI C/C++ Compiler

Hello,

I have tried the the example code from TI to use the AES ECB mode, and it works fine.

However when I modified the code to follow the pseudo code as in the MSP432 TM, to configure as CBC, I found that the generated cipher text is not the same as online generation.

After sometime I noticed that the generated cipher text was actually still same as expected in ECB mode.

I have verified that the registers did configure the MSP432 in CBC and the also the IV was loaded , but the output cipher text still follows ECB encryption.

Do you have a tested example code to use with MSP432 for AES 256 CBC with DMA ?

Or is there anything different needs to be done apart from the pseudo from the TM.
