S32k3 hse advance boot secure code

[vikmonti7804]

Hi ,

 I am using S32k3 HSE example demo code and using S32k3 hse advance boot secure code.

I am building this code with S32 Design studio but getting one error below:

make: *** [makefile:58: S32K344_Advanced_SecureBoot.elf] Error 1

Can you help me to solve it? Please find the screenshot.

Hi Robin,

         I have seen the file but my question is that , is this blinky binary will also go into mcu while flashing the mcu with firmware.

2. Is this blincky file behave as bootloader file for this firmware?

kindly explain your answers

Sorry I may not understand your question. Please correct me if there is something wrong with my answer.
1. Does this binary file blinky will also be flashed in the mcu?
Yes.
2. Is this blincky file behave as bootloader file for this firmware?
S32K344_SecureBootBlinky.bin is the application image in flash memory that need to be authenticated to perform secure boot.

Hi 

Prior to build and execute the code, **the user needs to** :
- Access the linker file and change the current address where the security file is located to match a location in their computers.

Did you build S32K344_SecureBootBlinky project first and change the address of S32K344_SecureBootBlink.bin? (C:\NXP\S32K3_HSE_DemoExamples_1_0_0\S32K3_HSE_DemoExamples\Secure_Boot\S32K344_SecureBootBlinky)

Best Regards,
Robin

Hi Robin,

          There are couple of questions, please answer .

Hi Robin,

 1.           I am also looking into the HSE_SHE secure boot example code which is using S32K344_SecureBoot_AppBL.bin file as input, Can you please give some details about this exaple code. Atlast we have to use HSE_SHE secure boot for our application.

2.  Where can I find the SYS_IMG for flash or is it bootloader file?

3. Can you provide one or two session training for the HSE secure boot on firmware level.

4. Which is better to adopt full memory or AB_Swap memory configuration? Advantages and disadvantages?

5. How to do The SMR installation service ? Explain with firmware screenshots or provide any good document because it is not clear in application note?

[Robin_Shen]

We provide Secure Boot application note including demo projects which explains all the steps in detail. It can be downloaded from: https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-auto-gener...

Application note can be found here:

Documentation -> Secure Files -> Secure Boot Application note v0.1.1.0 (AN744511)

Associated demo project can be downloaded here:

Hi Robin,

           Thanks for the reply, I need to understand the SMR in better way.

1. How SMR is working and linked with application and images saved in NVM .

2. How SMR is linked with cpu subsystems.

Kindly provide good documents with images or flow chart, or please prepare some diagrams to understand. its not clear in nxp documents.

All the information related to the S32K3 SecureBoot is under NDA (Non-Disclosure Agreement) the information is not public, and I am not able to share it due to the security levels when working with an automotive part such as this.

Please download Secure Boot Overview Training, it is introduced starting on page 17/32 of this document.

By the way, have you contacted your local FAE to ask if there are any HSE training videos?

Hi Robin,

            I am also looking into the HSE_SHE secure boot example code which is using S32K344_SecureBoot_AppBL.bin file as input, Can you please give some details about this exaple code. Atlast we have to use HSE_SHE secure boot for our application.

Kindly make a note and share for this example code in detail.

[vikmonti7804]

Thanks for your relpy.

I just want to know more, how this will work after flashing the code in mcu. Does this binary file blinky will also be flashed in the mcu or everytime this will try to find the file from computer. 

Because at last this all should go into mcu nothing will be on computer.

Can you please elaborate on this.
