Hi Reinhard,
Okay, it may be awhile before I get to this... Kinda busy at the moment.
Cheers,
Rick

Hi Reinhard,
Did you ever get the email below? I never heard back from anyone on this.
Sorry, did not see this mail.

Hi All,
Here is what I've done so far:
git clone git://git.denx.de/u-boot-atmel.git cd u-boot-atmel git checkout -b rework101229
- used CodeSourcery/Sourcery_G++_Lite:
/u-boot-atmel> /opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc --version arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2010q1-202) 4.4.1
Hopefully this compiler is okay, please tell me if it's not.
should work. Maybe you run into trouble cause of missing armv4 support in the toolchain. There are workarounds, just let u-boot build its own libgcc stuff -> 'USE_PRIVATE_LIBGCC'.
- looked at:
commit 0693923cd240f5d401be0a53cddcf0fb1d9ad9d3 in the current u-boot
- Make a bunch of changes but still have 2 warnings (see http://www.efn.org/~rick/pub/build.log):
cpu.c:37: warning: #warning Your board is using legacy AT91RM9200 SoC access. Please update!
Well, please update this board to use the new arm920t/at91 SoC code, see at91rm9200ek for example.
at91_emac.c:487: warning: dereferencing type-punned pointer will break strict-aliasing rules
fixed in 2321bfe425385494da8739d7d7e9dd3a5ca18a84
What should I do about these?
I made a patch file, please check it over. http://www.efn.org/~rick/pub/uboot.diff
At least these steps are missing:
- configure to use arm920t/at91, not arm920t/at91rm9200 (-> boards.cfg)
- set correct USART in config
- adopt includes in board file
best regards,
