5.3.4.2. Printing to the JTAG UART
The boot copier in this example prints information to the JTAG UART peripheral during the boot process. Printing is useful for debugging the boot copier, as well as for monitoring the boot status of your system. By default, the example prints basic information such as a start up message, the addresses in flash memory at which it is searching for boot images, and an indication of the image it ultimately selects to boot. You can add your own print messages to the code easily.
The advanced boot copier example avoids using the printf() library function, for the following reasons:
- The printf() library may cause the boot copier to stall if no host is reading output from the JTAG UART.
- The printf() library can potentially consume large amounts of program memory.
