NVRAM Commands

10.6.8 rewritemonitor
rewritemonitor
overwrites the monitor software in the onboard soldered flash
device with a new monitor image. It asks you for a source address and the size of
the new monitor image. Once invoked, the function gives you two opportunities
to exit without modifying the onboard flash.
CAUTION.
This function cannot recover from a failed write to the flash
device. If a failure does occur, it cannot print an error and the
monitor may no longer be able to boot the board. To recover,
you would have to rewrite the monitor from a socketed flash
device using the flashblkwr function.
DEFINITION
int ReWriteMonitor(void)
10.7 NVRAM Commands
The monitor uses on-board NVRAM for nonvolatile memory. A memory map is
given in Table 4-5, earlier in this manual. Portions of this nonvolatile memory are
reserved for factory configuration and identification information and the moni-
tor.
The nonvolatile memory support commands deal only with the monitor- and
Artesyn-defined sections of the nonvolatile memory. The monitor-defined sec-
tions are readable and writeable and can be modified by the monitor.
10.7.1 nvdisplay
nvdisplay
is used to display the Artesyn-defined and monitor-defined nonvola-
tile sections. The nonvolatile memory configuration information is used to com-
pletely configure the BajaPPC-750 at reset. The utility command
configboard
can also be used to reconfigure the board after modifications to the nonvolatile
memory.
DEFINITION
void NVDisplay(void)

fields. Each field is displayed as a hexadecimal or decimal number, or as a list of
legal values.
