|
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().

The minor device number of the ROMFS block. For example, the N in /dev/ramN.

The path to the ROMFS/External block driver device. This must match

|
EXAMPLES_MODULE_DEVMINOR for the case of ROMFS. Used for mounting the
|
|
file system containing the ELF executables to be tested. Default:
|

"/dev/ram0" for ROMFS, "/dev/mmcsd0" for the external file system.

---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.
