|
|
+
|
|
+.SH NAME
|
|
+kwboot \- Boot Marvell Kirkwood SoCs over a serial link.
|
|
+.SH SYNOPSIS
|
|
+.B kwboot
|
|
+.RB [ "-b \fIimage\fP" ]
|
|
+.RB [ "-p" ]
|
|
+.RB [ "-t" ]
|
|
+.RB [ "-B \fIbaudrate\fP" ]
|
|
+.RB \fITTY\fP
|
|
+.SH "DESCRIPTION"
|
|
+
|
|
+The \fBmkimage\fP program boots boards based on Marvell's Kirkwood
|
|
+platform over their integrated UART. 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). Boot images of different types,
|
|
+such as backup images of vendor firmware downloaded from flash memory
|
|
+(type 0x8B), will not work (or not as expected). See \fB-p\fP for a
|
|
+workaround.
|
|
+
|
|
+This mode writes handshake status and upload progress indication to
|
|
+stdout.
|
|
+
|
|
+.TP
|
|
+.BI "\-p"
|
|
+In combination with \fB-b\fP, patches the header in \fIimage\fP prior
|
|
+to upload, to "UART boot" type.
|
|
+
|
|
+This option attempts on-the-fly conversion of some none-UART image
|
|
+types, such as images which were originally formatted to be stored in
|
|
+flash memory.
|
|
+
|
|
+Conversion is performed in memory. The contents of \fIimage\fP will
|
|
+not be altered.
|
|
+
|
|
+.TP
|
|
+.BI "\-t"
|
|
+Run a terminal program, connecting standard input and output to
|
|
+.RB \fITTY\fP.
|
|
+
|
|
+If used in combination with \fB-b\fP, terminal mode is entered
|
|
+immediately following a successful image upload.
|
|
+
|
|
+If standard I/O streams connect to a console, this mode will terminate
|
|
+after receiving 'ctrl-\\' followed by 'c' from console input.
|
|
+
|
|
+.TP
|
|
+.BI "\-B \fIbaudrate\fP"
|
|
+Adjust the baud rate on \fITTY\fP. Default rate is 115200.
