Description
A flag indicating the type of Power-On Self Test (POST) performed by the Boot
Monitor during board startup. This parameter can have one of two values:
A flag indicating if a soft reset should be performed. This flag is used by the Initial
Loader to properly configure memory controllers and by POST to perform the
appropriate POST set. This flag can have one of two values:
Note:
A flag indicating whether the Boot Monitor will load and execute the run-time
image for the NPU. This flag can have one of two values:
The number of BOOTP requests that are sent by the Boot Manager over Ethernet
interfaces to obtain the IP configuration.
Depending on the flag, the SRAM memory is either rewritten with its own content
or filled with zeros.
Number of seconds of delay before launching the boot script.
A flag indicating whether traffic that comes over Ethernet interfaces will be traced
on the Boot Monitor console.
A flag indicating the type of IP configuration used for the debug Ethernet interface
during run-time image loading. This flag can have one of two values:
Purpose
Contains a Linux kernel image.
Contains a Linux root file system.
A compressed read-only file system (CRAMFS) that is mounted during boot time
by the Linux kernel.
An optional partition that may be used when Linux applications require a local
read-write file system. This partition is always mounted, but the appropriate
Memory Technology Device (MTD) exists only if the partition is manually created
from the boot PROM level.
Table 48
• short POST – short POST set will be performed
• long POST – long POST set will be performed
• normal startup
• soft reset
• image load – The Boot Manager attempt to load and execute run-time image
• command prompt – Boot Manager does not attempt to load run-time image
• automatic – IP configuration is obtained via the BOOTP protocol
• static – IP configuration stored as boot configuration parameter are used
Table
code
code, displays a command prompt and waits for operator action (for example,
diagnostics execution).
Soft reset does not perform SRAM write tests so that the content of SRAM
can be preserved.
