EmCOREFS

The information and/or topic discussed here is not up to date. emCOREFS is not compatible with emCORE r891+, due to breaking changes (new debugging method)

emCOREFS is a FUSE-based filesystem that uses emCORE's Monitor API to provide communication with device's FS. It is not yet complete, but most features are done. It runs on both Linux and Mac OS X.

For communication with the device, this application uses libusb 1.0.

Building

You need:

1. GCC/Make (Xcode on OS X)

2. pkg-config

3. libusb >= 1.0

4. libfuse >= 2.8 (or fuse4x on x64 OS X)

5. all dependencies of the above

Compiling

• standard build, no debug messages, only fatal errors on startup are shown.

make

• debug build, some debug/error messages are shown. libusb debug messages are enabled, too.

make debug

You can prefix any of these with

CFLAGS="-DDEBUG_USB_PACKETS"

in order to have a dump of the usb traffic that's being sent and received.

Testing

• run the build without FUSE debugging messages, going into the background if it connects to the device successfully.

make test

• run the build in the foreground, showing FUSE debug messages in the terminal.

make testdebug

Running

You need FUSE >= 2.8 installed. (or fuse4x on x64 OS X)

Currently tested on Linux (Ubuntu 11.04 x86) and Mac OS X (10.6.8 x64).

• Starting:

./emcorefs <mountpoint>

• Stopping:

fusermount -u <mountpoint as seen in /etc/mtab>

Known bugs/issues

• Write support not tested very well.
• Running FUSE with multithreading breaks file reading because of the way these are implemented on emCORE's side. Workaround: use the "-s" option.
• Most errors are not handled properly, EIO (Input/output error) is given in many cases where there's a more descriptive error message available. Will be fixed in the future.

Future plans

• Merge some functions that are doing similar tasks to reduce code duplication. Return proper error codes in FS operations.
