[U-Boot] [UBOOT] AVR32-UC3 (EVK1100) status

[U-Boot] [UBOOT] AVR32-UC3 (EVK1100) status

[Tobias Frost]

I received a new toy, one Atmel EVK 1105 evaluation board. 
(MCU: AVR32, AT32 UC3A 0512).

The board is quite similar to the EVK 1100. Checking the schematic, the
changes are indeed minor, (like channel for SPI1 instead of SPI0  for
Flash memory) 

As I saw on the list that there were some patches to support the 1100,
it seems feasible for me also to add support for the 1105. 

So the first question is: How stable / good is the support of the
EVK1100? I read on the avr32linux wiki that there are some issues
("commments needs to be adressed") but I found no details. 
So, does it make sense to use this as a starting point? 

I'm new to uboot development, so maybe you also have some pointers to
get started.

Thanks!

Hi,

I would recomend you to take a look at the comments posted on the mailinglist
earlier:
http://lists.denx.de/pipermail/u-boot/2009-January/thread.html#45925

As one of the developers which were workuing on this earlier I would say that
it is a good starting point for developing u-boot. If I remember correct, most
of the issues was due to an bug in the board we used. (We had to add a fat
load of external SRAM since code execution from SDRAM was unrelaiable,
and the CPU had to be underclocked.)

Also noted that I am not engaged in this project any more. We did this as a
student project, and delivered our result to Haavard Skinnemoen (@atmel),
which probably is the maintainer of this code now.

Best point to start is, i guess, to download the code, check that is compiles.
Then you can add a copy of the board config and customize this for this board.

regards
