[U-Boot] Howto u-boot an evk1100 ?

[Sril]

Hi Andreas,

Ok, I read you all and it's quite a pity.

I found recently a project call ethernut and it works fine with an unbuggy sdramc evk1100 with their c-code. Let's confirmed.

I'm not in the way to get rid of u-boot loader.
When test will be done, I think that evk1100 must working on u-boot.
Many files changed and api is different beetwenn u-boot-2008.10 (start) and u-boot-2014.04 (now).

Porting does not sound to me difficult when linux evk1100 jump is set.

Agreed. It's a far uncertain future indeed.
One can remarks that there is at least 3 prod procs in evk1100 (a0512es with sdramc bug and a0512es unbuggy (after 09-2008 series) and a0512 (like mine)).

I'm not a guru programmer but I discover with avr32 that Atmel gives tool and there is no open developper behind : avr32-toolchain has conceptualy 4 years now (gcc 4.4).

People like me does wants this : I only want all work and go directly to next step i.e. programming my eval project and don't want to spend months to have proper tools (binutils, gcc, newlib, uclib, gdb, u-boot loader, linux, rtlinux ...).

I found some conflictive answers on forum and other docs : it's IMHO because of a lack of well documented and recent maintain working developper tools.

All that b.llsh.t to concretly says that docs does not only be thinking in terms of file name but also content context for beginner.

Andreas, Best regards.
