SH3 and Redboot [newbie]


Hi

Our engineer has designed a circuit with a 7077 SH3 ship, 8Mb RAM some flash
and a 4Mb boot EPROM.  I would like to get linux booting using RedBoot as
the bootloader.  My first step will be to get RedBoot working, what
information should I get from the engineer?

He is not really interested in getting linux going on this board but is
willing to supply me with all the memory addresses that I think I will need
and also help with the schematic circuit.

Is anyone willing to give me some pointers on where to start...ie  what
memory addresses or information do I need for RedBoot to load?

I can programme the EPROM with an external programmer to load RedBoot,  the
engineer has said the EPROM is mapped at 0 so I assume I need to modify
RedBoot to setup the chip registers etc after the CPU jumps to address 0...

What information should I ask for regarding the serial port (for console)?

Perhaps there is a FAQ or HOW-TO that I haven't seen yet...

Any help is appreciated :)


Paul
