VxWorks
BSP Developer’s Guide, 6.0

An image that continues running from flash and is built from a project is normally
called vxWorks_romResident. Such an image built from the command line is
typically called one of the following image types:
vxWorks.res_rom
vxWorks.res_rom_res_low
vxWorks.res_rom_nosym
vxWorks.res_rom_nosym_res_low
bootrom_res
bootrom_res_high
An image that copies itself from flash to RAM and is built from a project is
normally called vxWorks_rom. Such an image built from the command line is
normally called vxWorks.st or bootrom_uncmp.
An image that decompresses itself and puts the results in RAM, and is built from
a project, is generally called vxWorks_romCompress. Such an image built from the
command line is called vxWorks.st_rom or bootrom.
If a boot loader loads a VxWorks image, whether from a local file system or from a
remote host, the image is referred to as vxWorks, regardless of how it is built.
A more detailed description of each image type is listed below. Much of this
information can be found in the file target/h/make/rules.bsp in your installation.
vxWorks
The primary VxWorks image that is loaded by a boot loader from a local file
system or from a remote host. If a downloaded symbol table is configured,
vxWorks requires the vxWorks.sym file.
vxWorks.sym
A symbol table that is loaded from the same file system and directory as the
vxWorks image itself.
vxWorks_rom
A VxWorks standalone ROM image programmed into flash that copies itself
to RAM for execution. This format is typically used when making an
application in ROM that does not include the shell or the symbol table. Because
these applications are usually smaller, this version does not use ROM
compression.
vxWorks.st
A VxWorks standalone image that is loaded by a boot loader from a local file
system or from a remote host. This VxWorks image has a symbol table already
linked in, so it does not need to load vxWorks.sym from a local file system or
