[U-Boot-Users] using u-bbot with new platform

[Marcos Lois Bermúdez]

Hello.

I'm a newbye in u-boot, i will use it in a hardware platform based in 
PXA255, iwill try to get ready the basic stuff, flash, RAM, uart, i will 
base it on any PXA255 board that already supported by u-boot.

My problem is that my hardware don't have a ethernet card, and it will 
be very usefull in the development process, i have a pcmcia card that is 
a tunlip_cs linux driver i think porting it, but i not have idea of what 
kind of considerations i need to taek in mind for pcmcia based card. If 
there anybody that try this, or another pcmcia card that have better 
support in u-boot, please help me.

Regards.

I don't have any answers on the PCMCIA issue, but one other option
that may be useful is to load images from a MMC card.  A MMC interface
is very easy to get working (3 wires).

I don't have mmc interface in the current platform. at this moment i 
will try go get basic system working, FLASH, RAM, UART, when it's done i 
will comming back to share my work on PCMCIA.

Regards, and a lot of thks.

So is now the number of wires a  measure  for  the  complexity  of  a
protocol hierarchy? I'm somewhat surprised.

Best regards,
