3.2.6 Advisory

Secure Live Firmware Update (LFU) Boot Modes are Deprecated

Revision Affected

0

Details

Secure LFU boot mode, if configured, will result in device reset if the memories have been secured.

Workaround

The latest firmware bank selection algorithm can be implemented as part of the flash custom bootloader instead of calling from ROM. This same custom bootloader can call the CMAC authentication algorithm (located in secure ROM) for flash content authentication after the latest firmware bank selection. The flash memory where this custom bootloader is located should be configured as Z1 secure memory.
