[U-Boot-Users] how can I find Mac address under u-boot
how can I find my ethernet device' physical address? I have read the FAQ and I still don't know how to use gen_eth_addr tool to generate random addressed.I double kick the gen_eth_addr and nothing happend!
You can "setenv ethaddr *****" under u-boot or set random address on kernel ether driver.

This is VERY BAD advice. NEVER, NEVER EVER use random MAC addresses.

The address is typically programmed into the deivce. In U-Boot, just type "printenv ehtaddr" to display the current setting.

"Double kick"? This is qualtiy software which is not used to being kicked. It simply refuses to work under such rough treatment.
Be friendly, and just call the applicatioin by it's name:
-> cd tools -> ./gen_eth_addr 3e:55:7a:55:ef:d3 -> ./gen_eth_addr de:b0:7f:c9:4e:a9 -> ./gen_eth_addr 9a:17:0d:df:1f:4a
There you go...
