Hi,



I'm using the RCm4300 and i have a problem that when i download the code to the

module then i connect the Ethernet cable to the module, the module isn't able to

detect that the cable is plugged, i have to turn off the power then ON to detect

the problem.



by the way, i found a problem in the fat library with the ucos,which is

the _fat_automount function is calling fat_UnmountDevice inline 3437 but it

should call _fat_UnmountDevice.



when calling fat_automount under the ucos, it should pend on a semaphore and if

it got it, the FAT API _fat_automount will be started the problem that the

_fat_automount is calling fat_UnmountDevice which is pending also on the

semaphore so will timeout and break the code.

i hope it help





Best Regards

MFawzy

for more info, this problem appears random not all the time

There is a bug in the ASIX chip that will cause it to not negotiate

correctly with some hubs/switches. The fix was to use a very long reset

to the chip, something like 3 seconds. It would work on a power-up but

not on later resets.



The bug was fixed in the Softools port of the stack. AFAIK, ZW never

implemented the fix. I also notice on the newer modules the no longer

feed a pin to the ASIX chip to use as a reset. So, your only option may

be to get a different hub/switch.

I've, unfortunately, just come across this problem. I'm really stuck because

I'm connecting directly to a PC via a crossover cable.



Anyone got any opinions on the following.



Adding code to try to cycle the interface if it detects it's down for more

than a few seconds.



Allowing an external reset to the board if the interface is down for more

than a few minutes.



Reconfiguring the Gigabit Ethernet port on the PC to lock it at 100FDX???





Any ideas appreciated..

An update. This problem occurred on a 3375 module, I was able to fix it by

locking the Gigabit Ethernet port on the PC to 100FDX.

I’ve succeeded at interfacing to my 2-line LCD display from my RCM4400W module, but I wish I could put all the LCD code into a separate file and #include it. I know Rabbit’s C compiler doesn’t support #include, but is there no way to achieve something similar? “#use” doesn’t quite do what I want – it only seems to know how to point into Rabbit’s own libraries. I want a library of my own.

Hi All



I am having an issue with Rabbit Web.



Sometimes I have to push the submit button more than once.



Anyone else out there have any pointers?

Seeing as how you submitted this question twice, maybe the problem is in your

web browser and not with Rabbit Web.

Nevermind...it only looked like you submitted it twice as viewed in my RSS feed

(the second post was evidently a quote on another answer).

How does one tell when a client has connected to the Ethernet or PPP

port of the Rabbit?



Regards



A.

You will already have done something like this...

       tcp_reserveport(PORT);

	 tcp_listen(&commsSock,PORT,0,0,NULL,0);



So now you must periodically call

	 tcp_tick(&commsSock);



And then when:

	 sock_established(&commsSock) == true

you know your client has connected.



You know the client has disconnected when:

     tcp_tick(&commsSock)==0





Hope this helps.

Kenny.

Hello Kenny



I am using PPP for the connection.



Where do I get the definition / structure for

tcp_listen(&commsSock,80,0,0,NULL,0);



I looked in TCP.LIB and tried to use that structure but I get an error

message:



I do already have



tcp_reserveport(80);



I get the following error messages when I add tcp_listen



line  577 : ERROR HUMIDITYPPP.C   : Expecting function or variable name.

line  577 : WARNING HUMIDITYPPP.C   : Wrong type for parameter 1.

line  577 : ERROR HUMIDITYPPP.C   : Invalid expression - need lvalue.



regards



A.

Suppose one wanted to transfer a binary file from a PC to the filesystem on the flash of an RCM4400W. I would have thought the Rabbit File Utility would do that, but it seems geared to downloading .bin files only (which I presume are the executables that the Rabbit processor uses.)

 

RFU does have a window in which you can specify all sorts of interesting things like “8 bit cold loader”, “serial pilot BIOS” and others, but none of them seem like random files like the kind I want to download.

 

Anyone know how to do this? Thanks…-BobC

You can use "#use" with your own libraries; but, you need to add your

libraries to the lib.dir text file.

Note: The lid.dir is read when DC program starts so you must exit and

restart the DC IDE for changes to lib.dir to take effect.
