Altium Live Desing Eval and Linux

Is there an implementation of Linux for the
Live Design Eval Board(Xilinx). May be a version of
uCLinux for Mircoblaze?

Thx

Hi Eric,

The Live Design Eval Board has only 1MB of RAM, there are some reports
getting mb-uclinux working with small (less than 4MB) memory but there
is no 'get it working in 1MB solution' - this is one problem.

You can make a Microblaze design that is 'uclinux ready' and test it on
livedesign board, but you should use EDK for that in order to have the
supported peripheral in place (OPB_INTC, OPTB_Timer, OPB_UARTLITE)

An interesting thing would of course be microblaze uclinux system
design without EDK using Altium Designer as SoC tool - unfortunatly
such a design does not exist - well the SDRAM support was added to
Altium Designer only in the release 6.3 (from 26 June 2006?), so there
is defenetly no uclinux that would work on system made with Altium
Designer.

Ok, thanks. If linux wont work,
what about ECOS, VxWorks,....?
Do You have an Idea?

1 VxWorks only supports PPC not MicroBlaze
2 eCos is not ported to MicroBlaze either

so both of them will not work on the live design eval board

uC/OS would defenetly work, for some while ago I tested it on
Microblaze, I think I got it all fitted into BRAMs, with 1MB SRAM you
should have no problems
