NAME

hps_dump − dump MVME338 memory to a host file

SYNOPSIS

hps_dump [ −f dumpfile_name ] [ −d dev_name ]

DESCRIPTION

Hps_dump uses the loader interface to upload all of the memory from the MVME338 host adapter board into a file.  This produces a snapshot of a system for later analysis and debug. 

To facilitate deciphering the memory dump, a number of things are stored at the beginning of the file.  The first 1024 bytes are defined as follows:

80 bytes  - identification string including version
80 bytes  - time and date of dump from host system
80 bytes  - comments
268 bytes - log table from the host adapter
32 bytes  - system Address table from GADDRS command
8 bytes   - address range of dump - starting and ending
476 bytes - pad to 1024 bytes total

OPTIONS

One or more of the following options may be selected:

−fSpecify an alternate dumpfile_name. The default is to write the MVME338 memory dump to the file hpscore in the current directory. 

−dThe default is to request the network configuration from the host adapter with device name /dev/xedt/mvme338_c0. 

EXAMPLES

To request a dump of memory using the default host adapter and dumpfile:

 hps_dump

To request a dump of memory using an alternate dumpfile and the default MVME338 host adapter:

 hps_dump −f hpsdebug

To request a dump of memory using both an alternate MVME338 host adapter and dumpfile:

 hps_dump −f hpsdebug −d /dev/xedt/mvme338_c1
