RE: Mac address in the DT
Hi, I am using 2.6.21 linux kernel with this bootloader. The ethernet driver in the kernel reads the mac address from the .dtb file.

Re: Mac address in the DT
Hi Wolfgang, I need to automate a sequence of commands. To do that I am setting a environment variable with the sequence of commands. And using run command run the environment variable. But one of the command uses in the command. So how do I save the command with quotes. Below is the command which I want to set in the environment variable. setenv set_mac cp 0xffec 0x10 1024;fdt addr 0x10 8192;fdt set /soc8272@f000/ethernet@24000 mac-address [00 22 00 33 00 55] But when I saveenv the command doesnot get save as fdt set /soc8272@f000/ethernet@24000 mac-address [00 22 00 33 00 55] Thanks Regards, Smitha Have you tried ...\[00 22 00 33 00 55]\ ?

RE: Mac address in the DT
Hi Joakim, I have tried it but it doesn't work. Just now found that with single ' quotes the entire sequence it works. Setenv set_mac 'cp 0xffec 0x10 1024;fdt addr 0xc0 8192;fdt set /soc8272@f000/ethernet@24000 mac-address [00 44 00 55 00 66];erase 0xffec 0xffec4000;cp 0xc0 0xffec 1024;bootm 0xfe06 - 0xffec' run set_mac For the above command I want to replace the mac address with the ethaddr How do I do that. I tried $ethaddr but I get extra : characters. Setenv set_mac 'cp 0xffec 0x10 1024;fdt addr 0xc0 8192;fdt set /soc8272@f000/ethernet@24000 mac-address $ethaddr;erase 0xffec 0xffec4000;cp 0xc0 0xffec 1024;bootm 0xfe06 - 0xffec' Regards, Smitha Please do not print this email unless it is absolutely necessary.
