5.21. FMC DualBoot
5.21.1. DEMO purpose

5.21.2. DEMO running result
Jumper JP13 to usart0, open program <21_FMC_DualBoot>, and then select
“START_FROM_BANK0” or “START_FROM_BANK1” in the target selection box,
compile them and download them to the EVAL board and run. Connect the COM0 port
of the EVAL board to the computer and open the HyperTerminal. When the program is
running, the serial port software displays the bank area where the currently running
program is located. Each time the tamper key is pressed, the BB bit in the FMC option
