|

This example supports a very, non-standard but also very convenient
|
||||
way of testing with example using CONFIG_EXAMPLES_MODULE_BUILTINFS.
|
||||
If this option is selected, the test modules will be built,
|
||||
installed in the module/lib/fsroot, then converted to a built-in
|
||||
ROMFS file system.
|
||||
|
||||
When the test runs, it will automatically create the ROMFS block
|
||||
device and mount the test modules for testing.
|
||||
|
||||
If this option is not selected, then the modules will be left in
|
||||
the fsroot/ directory. You can then copy them to, say an SD card,
|
||||
for testing on the target. That file system will need to be mounted
|
||||
such that CONFIG_EXAMPLES_MODULE_BINDIR refers to the directory
|
||||
containing the module binaries (unless the file system is auto-
|
||||
mounted)
|
||||
|
||||
NOTE: This option can only be used in the FLAT build mode because
|
||||
it makes an illegal OS call to ramdisk_register().

EXAMPLES_MODULE_DEVMINOR for the case of ROMFS. Used for mounting the

---help---
|

Link with the C library (and also math library if it was built).
|
||||
By default, all undefined symbols must be provided via a symbol
|
||||
table. But if this option is selected, then each MODULE test program
|
||||
will link with the C library and will not require symbol table
|
||||
entries. You probably will NOT want this option, however,
|
||||
because it will substantially increase the size of code. For
|
||||
example, a separate copy of printf() would be linked with every
|
||||
program greatly increasing the total code size. This option is
|
||||
primarily intended only for testing.
|
||||
|
||||
WARNING: Libc will not be built with -mlong-calls and this may
|
||||
result in runtime linking failures due to out-of-range functions
|
||||
calls.
