Chapter 5. Installation and Testing
The Atlas Developer’s Kit CD contains an srec2flash utility. The source code for this utility is part of
the
yamon/yamon-src-01.01.tar.gz tarball on the Dev Kit CD. The path in the expanded tarball is
yamon/bin/tools . To use srec2flash to convert the S-record file:
$ srec2flash -EL -S29 redboot.srec >redboot.dl
The Atlas/Malta Developer’s Kit CD contains an srecconv.pl utility which requires Perl. This utilty is part of
the
yamon/yamon-src-02.00.tar.gz tarball on the Dev Kit CD. The path in the expanded tarball is ya-
mon/bin/tools . To use srecconv to convert the S-record file:
$ cp redboot_ROM.srec redboot_ROM.rec
$ srecconv.pl -ES L -A 29 redboot_ROM
The resulting file is named redboot_ROM.fl .
Flash management
Additional config options
The ethernet MAC address is stored in flash manually using the fconfig command. You can use the YAMON setenv
ethaddr command to print out the board ethernet address. Typically, it is:
00:0d:a0:00:xx:xx
where xx.xx is the hex representation of the board serial number.
Additional commands
The exec command which allows the loading and execution of Linux kernels, is supported for this architecture (see
the Section called Executing Programs from RedBoot in Chapter 2 ). The exec parameters used for MIPS boards
are:
-b < addr>
Location to store command line and environment passed to kernel
-w < time>
Wait time in seconds before starting kernel
-c "params"
Parameters passed to kernel
< addr>
Kernel entry point, defaulting to the entry point of the last image loaded
Linux kernels on MIPS platforms expect the entry point to be called with arguments in the registers equivalent to
a C call with prototype:
