Mac Address change

Dear all,

I'm using lpc1768 controller with keil RTX RTOS. I need to know mac address of this controller is changeable or not? Because when i change a mac address value using "#define ETH0_MAC1 to ETH0_MAC6" then build it and download to controller mac Address gets changed and works fine but if i change it while controller running using "eth0_mac_addr[0] to [6]" mac ID gets changed and gets ping some minutes only after that it shows request time out.

Is it not Possible to change a MAC address while controller running?

Hi,

LPC1768 board has a unique MAC address, but the unique address is on the interface chip, not the LPC1768 itself.

I hope this helps,

Have a great day,
Soledad
