Hi Scott, thanks for your answer. Indeed, I have the datasheet from the manufacturer of the SoC. There is a project from Jeff Kent that treats about running U-boot an, ideed, a linux kernel on these chips. The specifications for this SoC could be consulted here: http://kthx.ath.cx/trac/nc600/raw-attachment/wiki/Hardware/NC600/POLLUX%20Databook%20Rev0.91.pdf
I'm new to U-boot, so I would like to know if some instructions are available to know the basics for developing a custom board for pollux. An initial approach was made by Jeff Kent. It could also be consulted on his trac here: http://kthx.ath.cx/trac/uboot/ I think that his project is very atractive. I bought 3 pollux thin clients and see linux working on them would be great! But I think it would need some work...
