lpc2366 lpc2368 ethernet 100M issue

[odescoubes]

Hello everybody,

I am using the LPC2366 with the DP83848 since several years, working fine until now : with the change of processor date code (previous date code  was year 2007, and now date code is year 2018) : with this latest date code, the ethernet link works only at 10M , and no more at 100M.

Has anybody already been faced with this problem?

Hi ,

we have connected the 50MHZ oscillator output direclty to the processor ethernet_clock_input  (instead of using the 25MHZ_OUT of the PHY), and it works fine now.

It looks like the 'B' revision of the processor can work with the 25MHZ_OUT signal, whereas the 'D' revision of the processor can't.

But why this issue wasn't included in the LPC23xx Errata sheet?

Regards

Olivier

Due the LPC2xxx is old I need to check where this is documented.

I am working on your problem on the internal case, 

but can you perform a swap test?

Maybe there is a problem with the hardware.

I will continue helping you on the internal case
