Boot flags:
Short POST contents
A bitmask describing which tests have to be performed during POST. If a given bit is
set then a corresponding test is performed during BMC POST:

• 1:1 – SRAM initialization; a flag determining the SRAM initialization method.

by BMC during board startup. This parameter can have one of two values:
- 0b Long POST (all tests will be performed)
- 1b Short POST (only selected tests will be performed)
definition)
the Boot Monitor during board startup. This parameter can have one of two
values:
- 0b Long POST
- 1b Short POST
flag is used by POST to perform the appropriated POST set and can have one of
two values:
- 0b Normal startup
- 1b Soft reset
load and execute the run-time image for the NPU. This flag can have one of two
values:
- 0b – Image load; the Boot Manager attempts to load and execute run-time
image code
- 1b – Command prompt; the Boot Manager does not attempt to load the run-
time image code, displays a command prompt and waits for operator action (for
example, diagnostics execution)
This flag is used by RedBoot* to initialize SRAM memory using one of the
following methods:
- 0b – Initialized with zero; the entire SRAM memory is filled with zeros
- 1b – Initialized with current value; every SRAM memory location will be
rewritten with the current value of such memory location to correct possible
parity errors
