Dear Eric Jarrige,

Stefano is right. "filesize" and "fileaddr" are dynamic variables, thet get created and updated on the fly. It makes no sense to pre-define them to any specific value. [Actually I have some changes in mind that avoid to save such variables with the environment at all.]
I understand - It make sense for me to wait for the new interface.
Which new interface do you mean? And why would waiting for it help you?
What do you mean by "push U-Boot through the serial port"? Any of the respective commands in U-Boot ("loads", "loadb", "loady") will automatically update the respective variables.
I meant to boot using the iMX internal bootstrap loader as U-Boot is not yet running. Alternatively I can download U-Boot a second time to have the environment variables initialized. It is just a longer process than the original one.
Are you aware of things like "env import" etc.?
And what makes you think that 192.168.0.10 might be a free IP address in my network? Or assume that 255.255.255.0 is the right netmask in this network?
This page lists "192.168/16 prefix", i. e. a 255.255.0.0 netmask. I know many development environments, and 192.168.x.x is used very, very often there. often with a /24 netmask, sometimes differently (at DENX we're using it with a /16 netmast, for example).
And there is absolutely NO guarantee that 192.168.0.10 is free, or that multiple users of your boards will boot simultaneously, or ...
The _concept_ of such a default address is broken.
These addresses may work for you, but they will not work for others, and thus it makes no sense to use them as defaults.
The armadeus BSP provide a user interface to customize the network parameters according to end user network environment.
Do you know the amount of efforts needed in any bigger organization to set up additional or to change existing network configurations?
Use DHCP?
Sure, DHCP is the best *technical* solution. I meant for static IP address?
Why does anybody need static IP addresses for the default case, i. e. for system bring up?
Best regards,
