These Commands are the Remote Serial Protocol.

Thanks for the suggestion about target.c

Yes - Use the Source Luke.

Not sure what you mean by $MF0,40 .. and $MF0,10

But -- ignoring that.

I presume you are using GDB remote in some form.

Look at the low level target read/write memory functions.

Example: "gdb/target.c - look at target_xfer_memory()"

Make your changes there - or what ever is the appropriate
target file(s) for your target. & build.

Writing to Memory and Page Alignment

[David Mc Kenna]

Hi all,

Is it possible to force gdb to write data to a target in a page aligned ( boundary
) manner?

For example, I have flash memory which is located at 0x8000 and the page size
is 256bytes. Under the current setup, gdb can overlap the pages and cause problems,
e.g. $MF0,40:.......#CS, here pages 0 and 1 overlap. Is it possible to get gdb
to split this command into two page aligned commands? i.e. $MF0,10:...#CS, page
0 written, and $M100,30:...#CS, page 1 written.

Thanks,
Dave Mc Kenna
