Decrypt CBC

Hello Everyone;

I have custom board with RT1176. In my application, i am decrypting the encrypted bin file. If i read all encrypted bin file at once and send the datas to decryption functions, it works correctly but as you can guess i have to use lots of ram space.

I change my code to decrease the usage of ram. I am reading data 256 bytes and after that decrypting the data for almost 200 times. When i debug my code, decryption process is done only one time(first cycle) successfully. After that, decryption process is not working.

What am i doing wrong? Can you help me?

Hi @Bkaya ,

  I find you are using the gmail to create the account and the question.

  Could you please help to use your company email to create the account and the question again?  Use the company email account question, it will have higher support priority.

  Then I will help you in your new case, thanks a lot for your understanding.

 

Best Regards,
