Hello

We will prepare a parameter sheet for CCG6. Therefore, I would like to clarify whether the following devices include encryption FW.

 

・CYPD6127-48LAXI

・CYPD6227-96BZXI

I think the device shipped from Cypress includes a FW (boot loader), and  is the FW included encryption function.

If so, please tell me what lkind of encryption function is included?

 

Best Regards

Arai

Hello Arai-san,

Yes, the bootloader firmware has encryption function. It is SHA256.

Hello Arai-san,

Please refer to Chapter 16 in CCG6 Architecture Technical Reference Manual for Cryptography block in CCG6.

Hello Mallika san 
I understand Cryptography block in CCG6.
 
However, this question is a confirmation for the CCG6 parameter sheet.

・CYPD6127-48LAXI

・CYPD6227-96BZXI

 We  are understanding that the above device includes a FW (boot loader) at the time of shipment from Cypress.
 
We want toknow whether this boot loader FW includes an encryption function or not. I want to know the software(boot loader)  has encryption function or not. If yes, what kind of encryption? I have to describe in the parameter sheet for bootloader F/W.
