Abstract
Many embedded systems use an embedded MultiMediaCard (eMMC) as the main storage device for such systems. When the eMMC for an embedded system is connected to the host Central Processing Unit (CPU) through an intermediate device, such as a Universal Serial Bus (USB) bridge, recovery from a transient eMMC failure, such as a single-event upset (SEU), is not available and such a failure could bring down an entire network. For example, conventional recovery processes for a system that experiences such a transient failure due to an SEU issue typically involve performing a system power cycle, which can cause significant network disruptions. In order to address such shortcomings, a recovery process is proposed herein that can detect a failure condition and automatically recover without the need for a power cycle of the system, thereby limiting the network impact of such a failure.
