Write-back the modified data block into the targets memory space.
If possible try to put a target WRITE program into our target workspace.
And transfer the Write-data via DCC.
If this is not possible write the memory via JTAG.

| int gdb_invalidate_Ram_Buffer | ( | void | ) |
Mark all cached RAM - Data is being invalid now.
Also invalidate RereadROM and Appl.Flash since this might have been changed at next debug entry, too.
Oh. better do not invalidate workspace (we should write even the old/modified data back)
