Re: [ts-7000] Re: Functions for Peeking and Poking Memory and I/O

["Eric Robishaw" <>]

I assume the -mcpu=arm9 flag is only needed when cross compiling from another environ?
Or is that required when compiling on the TS-7800 as well?

Some more:

1) Be sure to compile with the flag "-mcpu=arm9".

2) The functions I posted are not especially efficient. Each time you
call one, it opens the /dev/mem device so it can access the memory
and/or I/O, then does the peek or poke, then closes the device. This
is a lot of operating system overhead.
2a) A better way would be to have some persistence, such as in a
static variable or a C++ object, so we could just map once, then peek
and poke into the memory whenever we need to.
2b) Even better would be a driver in the kernel itself. Maybe later...
