In preparation for a release, move the new (partially incompatible with the
previous version) features on top so they will become immediately apparent in the release notes. git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@1233 81a1dc3b-b13d-400b-aceb-764788c761c2

----------------------------------------------------------------------
|
||||
Current:
|
||||
|
||||
* Major changes compared to the previous version:
|
||||
|
||||
- Programmer types in configuration file are no longer keywords but
|
||||
specified as string.
|
||||
|
||||
So you need to change 'type = XYZ;' to 'type = "XYZ";' in own
|
||||
config files. (internal: The parser does not need to know all
|
||||
programmer types now, new programmers will update only the table
|
||||
in pgm_type.c.)
|
||||
|
||||
- The erase cycle counter (formerly options -y / -Y) has been
|
||||
removed.
|
||||
|
||||
- Specifying a -U option without a memory type (short form of
|
||||
option argument list) now defaults to "application" memory for
|
||||
Xmega devices, and "flash" for everything else. This ensures
|
||||
the bootloader is not touched.
|
||||
|
||||
- For programmers that support it, the default erase method is a
|
||||
page erase now, rather than a chip erase (Xmega only).
|
||||
|
||||
- Keep track of input file contents
|
||||
|
||||
Memory segments are being tracked to remember whether they've
|
||||
been actually read from a file. Only segments that came from a
|
||||
file are being programmed into the device, or considered for
|
||||
verification. This drastically improves handling speed for
|
||||
sparse files (e.g. files that have a second bootloader segment),
|
||||
and it ensures the device contents is actually compared for
|
||||
everything mentioned in the file (even in case the file has
|
||||
large 0xFF blocks).
|
||||
|
||||
- The -U option now accepts ELF files as input files, and extracts
|
||||
the appropriate section contents that matches the requested memory
|
||||
region.
|
||||
|
||||
- Programmers and parts lists
|
||||
|
||||
They are now sorted at output with '-c ?'/'-p ?'. (patch #7671:
|
||||
Sorting programmers and parts lists for console output)
|
||||
|
||||
Programmers and parts lists in documentation generated from lists
|
||||
mentioned above. (patch #7687: Autogenerating programmers and
|
||||
parts lists for docs)
|
||||
|
||||
Output list of programmer types with '-c ?type', add list to
|
||||
documentation
|
||||
|
||||
- Configuration files now accepts parent parts/programmers, parts
|
||||
starting with '.' (eg. .xmega) are not included in output parts
|
||||
list and can be used as abstract parents
|
||||
|
||||
(bug #34302: Feature request : device configuration with parent classes)
|
||||
(patch #7688: Implement parent programmers feature)
|
||||
|
||||
- Additional config files which are read after default can be
|
||||
specified on command line using '-C +filename'
|
||||
|
||||
(patch #7699 Read additional config files)
|
||||
|
||||
- "Safemode" can now be turned off by default in a configuration
|
||||
file.
|
||||
|
||||
- The new option -l logfile allows to redirect diagnostic messages
|
||||
to a logfile rather than stdout. Useful to record debugging
|
||||
traces, in particular in environments which do not offer
|
||||
shell-style redirection functionality for standard streams.
|
||||
|
||||
- When leaving debugWIRE mode, immediately retry with ISP rather
|
||||
than bailing out completely.
|
||||
|
||||
- The USBasp programmer implementation now supports detailed traces
|
||||
with -vvv, and device communication traces with -vvvv.
|
||||
|
||||
- The "verbose" terminal mode command allows to query or modify the
|
||||
verbosity level.
|
||||
|
||||
* New devices supported:
|
||||
- ATmega48P (patch #7629 add support for atmega48p)
|
||||
- AT90PWM316 (bug #21797: AT90PWM316: New part description)
