M52233DEMO + NICHELite (Web Server)

jesconsa — Thu, 29 Mar 2007 17:24:10 GMT

Hello. I'm studing the NicheLite with a M52233DEMO Board. In somewhere in the forum i found the solution for doing a Make of the NicheLite's sample project. I have also change the IP, Gateway and Subnet Mask (in main) for have the board working in my LAN. When i download and start debugging, i get the following message in the Debug window:

Program "example_flash" is executing.
Choose Break from the Debug menu to stop it.

But when i try to connect with the IP i put in main.c I can't connect with the board. There isn't any ping with this IP. What I am doing wrong?.

Thanks for help.

Jesus.

Hi Jesus,

I'm a newbie on this forum, but I hope I can help you out. I am using the MCF52235EVB but it looks similar to your board.

OK - "example_flash is executing" this is not an error message, just the debugger elling you that it is running.

Second - can't ping your board at the IP address that you specified. You sure you programmed the board OK? Quick way to check is to connect up the serial port - UART0 to hyperterminal 115200 8N1 and hit return a couple of times. You should see a prompt INET> where you can type help to get some commands. Try IP - I think that will tell you the boards IP address. Alternatively, just turn off the board, remove the MultiLink and then turn on the board - you should see the stack boot in the hyperterminal window. Check the IP address.

If the IP address is the one that your pinging, you have a PC probelm. Firewall? Are you connected via router, or directly to the board with the supplied crossover cable? I had some diffieculty with my NIC settings - try changing the NIC to 100 Mbits/s half duplex - that seemed to work for me.

Any ideas from you more experienced guys???

Are you sure you uploaded the new firmware to the board by reprogramming the flash?

Thanks Marcia and Kremer for answering. The problem was that i didn't really program the board. I have the M52233DEMO board but i had to use the init file for 52235 for the CW to program the firmware correctly (In CW --> Tool --> Flash Programmer). It doesn't work with the Init file for the 52233 processor. With this change I could erase and then flash the board without problems.

Now i'm trying to see how can i change the IP address dinamically in the board.

Thanks again.
