Date: Thu, 19 Jul 2001 04:40:00 -0000 [thread overview]

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
