networking without OS Support

Hello ,

I am trying to run networking application without Uc/OS-II Support, (not using standard UDP_Offload or Super_Loop)

for this i have choose the simple socket server server (RGMII) example and strip out OS feature one by one,

at the end it gives some error regarding

1. FindLastFlashSector

2. generate_and_store_mac_address

3. get_board_mac_addr

etc.

though i have add the network_utilities.c and network_utilities.h but still i am facing the problem

(see the attached printscreen of error)

i am using Altera Cyclone-II Development Board "Embedded Development board"

i have attached the c files

1.network_utilities.c

2.network_utilities.h

3.simple_socket_server.c

4.tse_my_system

Regards

kaushal

    Those errors are due to a typo in simple_socket_server.c

    You included

    # include "network_utilities.c"

    instead of

    # include "network_utilities.h"

    Not done this myself, though might get there in the next few months. But I note that it says "multiple definitions" rather than not defined. If you look at your error list, it shows that you have one definition on line 23 and it is redefined on line 300 (or similar - can't see your attachment at the moment!). Have you got two copies of the code here?

    I've not told you in the previous post, but I was concerned you would be able to run an interniche application with neither OS nor superloop mode.

    The alt_iniche_init and netmain functions are supposed to create specific tasks with OS. If you call them in a non-OS environment they probably generate some sort of exception or they are possibly blocking, thus preventing your application from working.

    hello Cris,

    me too think like this but , adding little delay after hardware initilize function alt_iniche_init() and netmain() ...it seems that it take MAC address and other things...but it stuck at Auto Negotiation pass etc(please see the print screen )

    TK_SLEEP is a OS specific function (or maybe a macro): it is supposed to release the control to other tasks, but you don't have any, so you can't use it.

    I've seen non-OS implementations of sleep functions but they are blocking and they are only meant to add the time delay.

    so is there any other way to go forward ...i mean what make hardware initialize up to "Auto Negotiation pass" not beyond that.

    it seems that it going to work...if it go up to auto negotiation.

    Up to MAC and PHY initialization, OS is not involved, since those are execute-once functions.

    You need OS features, superloop or any other interrupt scheduled process after inizialization when you really start sending and transmitting packets, especially if you need to manage a complex trasport protocol like tcp.
