Hi, all.

I'm trying to use RedBoot in a SH7750 board. I re-built RedBoot image
and programmed it into a ROM, but the "RedBoot>" prompt doesn't come.
The connection is a serial line (SCIF port of SH7750) and I used
minicom as terminal software.

Bootup message is:

--
RedBoot(tm) bootstrap and debug environment [ROM]
Non-certified release, version UNKNOWN - built 11:55:49, Sep 23 2002

RAM: 0x$T0210:8000b488;0f:0c0024f8;#5c

And any key hit, I got string '$T0210:8000b488;0f:0c0024f8;#5c'.

What is this means? It looks like GDB stub output, but user's guide
says GDB stub doesn't start until got '$' character. 

The target board is named OYO105, which is only slightly different
from cq7750, mainly in its memory maps. I copied and changed cq7750
code as to fit to it. I'm not sure my change is perfect, so I checked
some times, but I couldn't find mistake. If you have any hint, please
inform me.
