Number of MAC Addresses (1-64) : 10 ^C <- more whoops While interacting with the CFE trying to identify arguments that are passed to the target's operating system at boot, the system configuration was accidentally corrupted: CFE> b This post walks through resolving a situation where a target has been 'bricked' with a creative methodology.ĭuring some downtime, I was poking at an off the shelf consumer router that was using Common Firmware Environment (CFE) as a boot loader. In some cases fixing the target is as simple as performing a "factory reset", others may be slightly more involved and require flashing the target using a debug interface (JTAG/SWD/*) or manually flashing an external storage device (SPI/NOR/Nand/eMMC). Often when assessing an embedded system, changes can occur (intended or otherwise) that cause the target system to enter a state where it no longer works ('bricked').
