Problem with MAC - Ethernet

Started by Gustavo Alonso June 7, 2010
Hi everyone,

I'm currently having problems with the MAC_MAC1 register on a board similar to the MCB2300. I'm trying to run the easyweb keil example but it crashes when MAC_MAC1 = MAC1_PASS_ALL;
I'm debbugin with the ulink2 but when I run that line it crashes with error "Could not stop arm device! Please check the JTAG cable".
Has anyone solved this problem?

Thanks in advance
Best regards
Gustavo

An Engineer's Guide to the LPC2100 Series

Probably, it has something to do with the ENET_TX_CLK
or ENET_RX_CLK setting:
http://www.keil.com/support/docs/3358.htm

and check how the MAC is connected to the PHY on the board,
if the connection is wrong, you willl have a H/W fault when
you access the MAC1 register.

best,
Tom
