The following table gives default names and types of the boot files.
Table 20 Default names and types of the boot files
Boot file
Main boot file
Backup boot file
Secure boot file
Note that:
The application images for system boot can be type M, B and S, but not type N/A. You
can store them in Flash memory, but only one for each. For example, if an M+B file exists,
it is impossible to have another M or B file. If you change the file type of another file to B,
the M+B file becomes a type M file.
You can modify the file name of an application image in Flash memory using the
command after it boots.
You cannot modify the file type of the type S application image file, but you can modify
the file type of type M/B and N/A application image files in the Boot ROM menu or using
commands after the application image boots.
Secure boot file is the last resort for system boot. You can download it in the Boot ROM
menu and must name it secure.bin. However, you cannot modify this file or change the
type of another file to S. If you change the name of the secure boot file with the rename
command after the system boots, the file is removed from Flash memory. To use the
secure boot file after that, you need to download it again.
