I see. It seems your first problem is that you don't understand how to enter a subject in the mailer?

The first problem is that i can't find my evaluation board in config files. how i can build u-boot withou this file?

If ther eis no config file, then there is probably no port yet. In this case you will have to port U-Boot.

Need i to write my board configuration?

Yes, and all the rest which is necesary to complete a port.

what memery is needeed to uboot? i want to put it in flash memory.

memery = memory? U-Boot needs some ROM (flash is fine) and RAM to run.

i want to load linux via Ethernet and write into Flash memory, how i do it?

Read the manual and the FAQ.

Thanks to give me some explanations, because english is not my language, and it is very difficult to find documentations in french.

We will try to help independent of your language skills. However, you _are_ supposed to read the documentation (README, manual, FAQ). And before posting.

Best regards,
