Hi Andrey,

I have downloaded the 2.1.1 version. I have a problem whit the ping comand when i send it from my terminal program. It puts: "Request timed out" but when i do from my command-line environment on the host PC, it goes right.

Any idea of what is happening??

Thank you!

[butok]

Hi Alberto.

Juts tested, - both IPv4 and IPv6 pings works very well, - not able to reproduce your issue.

Please submit it to the :http://sourceforge.net/tracker/?group_id=253892&atid=1126920

Describe here all your settings (address, netmask etc.) and other conditions (via router, direct connection).

Thanks,

Hello Andrey,

thank you very much for your work. Since 3 years, I use FNET stack on MCF52233 microcontroller when I have ethernet project.

For a new project, we will need SNMP. Do you plan to add this service to FNET stack during 2013 ?

Thanks for answer,

best regards,

Thomas RETAIL.

Thanks Thomas,

Implementation of the SNMP server is in my wish list, but there is no concrete plan or schedule.

FNET does not have sponsor => the development is not regular => no concrete plans.

For your new project, please do not rely on availability of FNET SNMP server during 2013.

In any case, your possible contribution to the FNET project is welcome.

Thank you,

Hi all,

I'm successfully using FNET on a Kinetis K60; I need to make my embedded device discoverable on every possible network class, even if built-in programmed IP Address, Subnet Mask and Gateway aren't matched with that target network (example: factory programmed IP,MASK,GW in fnet_user_config.h and the module installed in a network with different setup).

Do you have any hints for me? I think I need a sort of uPnP implementation.

Thanks in advance for your help. :smileyhappy:

Hi Andrey,

congratulations for the excellent 2.0.1 work.

Will you plan to implement RTP (Realtime Transport Protocol) in FNET? :smileywink:

[butok]

Thanks,

I do not have RTP in my current plans.

But a contribution is welcome :smileywink:

Hello,

i include the stack and the example project.

My question now is, is it possible to start the http webserver direct without calling "fapp_main" ?

regards Peter

[butok]

Hi Peter

Yes. You may initialize & start & use it  without calling fapp_main().

The fapp_main() is just only demo application, that is used mainly as reference or example of the FNET usage.

You may start and use any FNET service from your code. But it is always better to look at the demo source code to avoid many mistakes.

Best regards,

Andrey

Hello,

I'm using FNET 1.1.2 on MCF51CN128, because I need to develop a serial to ETH converter to send over UDP some strings read from serial port.

Is it possible and how can I do to send UDP packet to multicast group?

best regards

Gianluigi

[butok]

Hi Gianluigi,

>> Is it possible and how can I do to send UDP packet to multicast group?

Yes.

In current FNET 1.1.2, you may send multicast UDP packets without any changes, just use the multicast group address (instead of unicast) as destination for sending function. For stack, it is no matter if it is unicast or multicast (destination). The Etherenet driver detects the muticast IP address and generates & places multicast MAC address into output frame.

FYI:

    Current 1.1.2 version does not have support of joining/leaving of multicast group

    => so you are not able to receive multicast packets in FNET.

    Fortunately, now I am working on full multicast support and it will be available in the next FNET version 1.2.

    It will have:

       - IP_MULTICAST_TTL socket option, which defines TTL for outgoing multicast packets.

       - IP_ADD_MEMBERSHIP and IP_DROP_MEMBERSHIP socket options,

         which joins/leaves IP multicast-group membership.

       - Basic support of IGMP protocol.

      - Other changes.

    Actually it will be ready soon, and if you want to test/try it earlier just write to Andrey.Butok@freescale.com.

Thanks,

Andrey Butok

[Gianluigi]

I tried to send udp packet to address 239.0.0.10 and I see with wireshark multicast bit flag is active, but the receiver does not receive the packet. I attach capture file.

What is wrong?

best regards

Gianluigi

[butok]

Hi Gianluigi,

The FNET sends multicast datagram (based on your .txt.)

So the issue somewhere in receiving application or stack – no help from me.

Be sure that your receiving-socket has joined the multicast group on the correct interface.

Best regards,

Andrey Butok.

Hello,

is  there any tutorial how to install or integrate the FNET stack in my existing project ?

Regards Peter

[butok]

Hi Peter,

You may look at “How-to: Add FNET Stack to an existing project“ http://fnet.sourceforge.net/manual/how_to_add_fnet.html

GREAT!

THANKS A LOT

Hello,

i include the stack into my project and create the fnet_user_config.h in the source folder.

now iam getting the error

"the file 'fnet_config.h' cannot be opened    fnet_arp.c"

the file exists in the FNET_STACK folder. Shall i move it to another place ?

regards Peter.

[butok]

Hi Peter,

I guess you are using CW10.x (or other compiler), as CW7.2 handles it very well.

As your project does not see some header files, it means you should control your project settings to be sure that all paths to header files are there and are correct (it is compiler/IDE dependent).

Best regards,

Andrey Butok

[PEGE]

I try to change/add the FNET folder for the header.

Now I got on every include (from fnet files) the information

"unresolved inclusion"

what wrong ? I am trying for hours and hours but no difference

I am using CW 10.x.

Further I get the warning

Cannot open file fnet.comp.asm.h

and

include: Can't continue

regards Peter
