Yes, that corroborates the flash table, which says that the NAND flash
starts at 80010000. (I don't know yet whether it actually *starts*
there, or whether it's mapped at 80000000 and the bottom 64kB are masked
by the NOR flash... if so, there might be something interesting there.
I'm thinking of the BBC MOS, where if you looked in the section of the
MOS ROM that was masked by the I/O area, there were the author's

First thing I want to try setting the baud rate a bit higher --- I don't
have all week!

Yeah, that's what it's for. (I wrote a very similar program a few years
ago to talk to the SingleStep monitor. Trust me, PBL is easy in

hri.sourceforge.net has CVS, doesn't it?
