AM2634: RBL and SBL Questions

Jett Ptacek

Part Number: AM2634

If I create my own RBL do I have to have it enter to a SBL or can I just have it enter my application's entry point? 

I have found the examples of different SBLs. Is sample code for the RBL located somewhere?


Thank you,

Jett

    Hi Jett,

    RBL stands for ROM Bootloader and SBL stands for Secondary Bootloader. ROM Bootloader is part of ROM inside the SoC and modification of the same is not possible. ROM is part of Secure Boot and other security features making the ROM code highly confidential and non-sharable to customers.

    Although, the RBL is a fixed code, the SBL is a way to customize the initialization by the customer. We provide different SBLs so the customer can choose between different source of boot.

    Hope that helps.

    Best Regards,
    Aakash
