MCB2300 ethernet problem

Started by vivek singhwal March 30, 2007
Hello all,

I am trying to develop a board similar to MBC2300 for LPC2368 actually I need only UART and ethernet module. This is the first time my interaction with ethernet. I tried the same connections for DP83848 as provided in MCB2300 Schematic but unfortunately it is not working out me and I am not able to figure out the problem.

Also I am not using any Ferrite Bead - SMD ( L) as mentioned in ENC28J60. Not sure whether it requires with DP83848 or not.

Is there any way that I can check or debug my connection from magnetic LANJACK to DP83848 as Link LED is also not blinking?

Can any one have suggestion for this?

Thanks and Regards,
Vivek

I had an issue with the lpc2368 and ethernet.
I had to run the clock at 48 Mhz to work.
can you give this a try and let me know if it works.
there is an lwip demo on the files area you can use.

I used the ethernet with MBC2300 Eval Board and with a specifich device.
All works fine for me. Have you enabled the ethernet in the power control register?

PCONP |= 0x40000000;

I have simple used the EasyWEBSample to test my specific hardware.
I use nichelite.for.lpc on the developer board in order to evaluate a possible use for future implementations.

Both test (DHCP in nichelite) works fine, but i don't stress them very well.

Bye

Hi Rudy,

From your comment I guess you have been using the ethernet on the LPC23xx. Does your code check the status in the receive descriptor for the packet that has just been received? I have been doing this and have found that every packet I receive has a CRCError, but the packet is all there and correct.

I have tried many things, and would like to know if it is my board design, or something out of my control. I aren't using the DP83848 PHY in my design like on the MCB2300 dev board.

Many Thanks
Chris Cook
