Q55 / 100
What challenge does "firmware over-the-air" (FOTA) update introduce for resource-constrained devices, and how is it commonly addressed?
Correct! Well done.
Incorrect.
The correct answer is A) Limited storage may not fit two full firmware images; common solutions include delta updates (only sending changed portions) or dual-bank flash storage allowing rollback if an update fails
A
Correct Answer
Limited storage may not fit two full firmware images; common solutions include delta updates (only sending changed portions) or dual-bank flash storage allowing rollback if an update fails
Explanation
Constrained devices often use techniques like A/B (dual-bank) partitions, allowing the new firmware to be written to an inactive bank and verified before switching, with the ability to roll back if the update fails.
