Boot image files will typically -+contain a second stage boot loader, such as U-Boot. The image file -+must conform to Marvell's BootROM firmware image format -+(\fIkwbimage\fP), created using a tool such as \fBmkimage\fP. -+ -+Following power-up or a system reset, system BootROM code polls the -+UART for a brief period of time, sensing a handshake message which -+initiates an image upload. This program sends this boot message until -+it receives a positive acknowledgement. The image is transfered using -+Xmodem. -+ -+Additionally, this program implements a minimal terminal mode, which -+can be used either standalone, or entered immediately following boot -+image transfer completion. This is often useful to catch early boot -+messages, or to manually interrupt a default boot procedure performed -+by the second-stage loader. -+ -+.SH "OPTIONS" -+ -+.TP -+.BI "\-b \fIimage\fP" -+Handshake; then upload file \fIimage\fP over \fITTY\fP. -+ -+Note that for the encapsulated boot code to be executed, \fIimage\fP -+must be of type "UART boot" (0x69).
