Retrieval of the OBFL message
If the hardware is defective and the system cannot boot up, any data in flash is inaccessible. In that case, use
any one of the following methods to recover OBFL data:
•
Read the flash through JTAG: this requires provisions in hardware design and back-end hardware and
software support tools.
•
Repair the system; boot it; use the OBFL CLI commands.
