AM263P4: Validation of New Firmware

Part Number: AM263P4

Hi,

In AM263Px, if there is new firmware update to be loaded into external flash, first it needs to be copied into L2 memory and by using OPSI module commands, firmware is loaded into Flash.

But what if the firmware is corrupted and we dont know about it and stored in Flash by above process.

However, I want to check for the valid Firmware and load into Flash, How can I do this? Is there any validation from HSM?

    Hi Geetha,

    HSM Does NOT validate firmware on flash during programming. Validation happens only when SBL loads firmware from flash to RAM during boot. There is no pre-validation mechanism before flashing. You must rely on SBL's boot-time checks to catch corrupted images.
