Hello, Has anyone had trouble communicating with the Mini2440 via DNW? I have two mini2440 and suddenly I'm not being able to send commands to one of them. Strange thing is that the mini2440 loads perfect to the OS in flash memory and when in nor it loads the bios but when I type a command it wont read it!! Any ideas or suggestions?! Thanks!!
Hi, Maybe its a problem with the serial cable. Have you tried another one? Regards, Andreas
Yup... I tried with both of my cables and I'm still not able to send commands via DNW. :(
Hi, I've nearly the same problem. I can't connect the Mini2440 through DNW. I think the main problem is that the usb driver doesn't work. I tried out both ways to install the usb driver. The driver setup passed through without any problems (like it seemed to me). At the manually installation I copied the "SECBULK.sys" to C:\Windows\System32\drivers and selected the "SECBULK.inf" at the Windows driver installation interface but it can't install it. I thought the board may be damaged but as I connected it to a vga display linux booted up normally. So does anyone have an idea to solve this problem.
Well, I got a hint that solved my problem...just switch on the NOR-Flash and power up the board again. Now my PC recognize the board and even the driver fits.
Hi wanderer, Do you have solve your problem? From several months, the communication between my mini2440 and DNW works well but today, I have exactly the same problem as you!
Hello, I don't know if it helps, but I encountered a similar problem a few days ago. My mini2440 which has always worked correctly refused to send traces on PC terminal. I tried on several hosts but got no message from the mini, even in NOR BIOS mode. For a reason I don't know, when I used the BIOS in a "blind" way, all the actions I requested were executed correctly but still with no trace on the terminal. I plugged the serial cable in the other way, and don't ask me why, it worked. Now I'm able to get traces on the terminal and send commands to the mini. I don't know what was the problem as a serial cable should be symetrical, and I checked before that everything was correctly plugged... regards
Heard of this happening before. Try turning the cable around and see if the problem comes back. The only thing that comes to mind, if a wire breaks off one terminal AND then connects to another active terminal I could see the cable "looking" different from both ends.
hi every one, could u plz help me..
my prob is iam unnable to see the characters clearly when iam connecting to
the mini2440 thru the DNW..showing some unwanted sybols and charecters in
between.same problem when iam trying thru ubuntu also. baudrate used is

I spend a day to figure out how to resolve this problem and I found really interesting solution. Do not use usb if you have RS232 connector. because you have com connector , your operating system find it as COM1 and DNW communicate with com1. I didn't find usb com number. that is why I prefer RS232 or com connector.
you could just use the onboard com port with your PC, or disable it, windows will happily allow you to reassign the com1 name to a usb to serial adapter.
what I found in loading windows into the board is that you can not program the device without usb. but I can not see vivi menu without com port. I mix them (seeing menu with com port and sending data with usb port) and it really worked.
