Native Execution of U-Boot
|
||||
==========================
|
||||
|
||||
The 'sandbox' architecture is designed to allow U-Boot to run under Linux on
|
||||
almost any hardware. To achieve this it builds U-Boot (so far as possible)
|
||||
as a normal C application with a main() and normal C libraries.
|
||||
|
||||
All of U-Boot's architecture-specific code therefore cannot be built as part
|
||||
of the sandbox U-Boot. The purpose of running U-Boot under Linux is to test
|
||||
all the generic code, not specific to any one architecture. The idea is to
|
||||
create unit tests which we can run to test this upper level code.
|
||||
|
||||
CONFIG_SANDBOX is defined when building a native board.
|
||||
|
||||
The chosen vendor and board names are also 'sandbox', so there is a single
|
||||
board in board/sandbox/sandbox.
|
||||
|
||||
CONFIG_SANDBOX_BIG_ENDIAN should be defined when running on big-endian
|
||||
machines.
|
||||
|
||||
Note that standalone/API support is not available at present.
|
||||
|
||||
The serial driver is a very simple implementation which reads and writes to
|
||||
the console. It does not set the terminal into raw mode, so cursor keys and
|
||||
history will not work yet.
|
||||
|
||||
|
||||
Tests
|
||||
-----
|
||||
|
||||
So far we have no tests, but when we do these will be documented here.
