AM2431: Backup Boot Condition

Hideaki Matsumoto

Part Number: AM2431

Hi,

Could we have a detail explanation of the Image Integrity Check described in Figure 4-3. Boot Process in the TRM ?

What’s the condition to switch to the backup boot ?

Thanks and regards,
Hideaki

Hi Hideaki-san,

This is the checking for the legitimacy of the SBL by the RBL. Basically the SBL should have been signed and has the correct format as mentioned in the AM243x MCU+ SDK: Understanding the bootflow and bootloaders (ti.com), in "Preparing the SBL for boot"

Best regards,

Ming
