bb9ae67aee Day of testing and minor edits. 
The RTC might be busy at startup.
This seems to be working - code successfully uploaded, after I got all the fuses right.

4c12f27e66 New version of optiboot for Mega0 and xTiny AVRs. Uses NVMCTRL, and of course all of the peripherals have changed. 
This is an initial commit of code that compiles.  There's no reaon to expect it to be working yet!  (but: only 430 bytes, with EEPROM support!)

ba257540f8 restructure the Virtual Boot code so that it is easier to read. 
These are preprocesing and commenting changes, and do not cause any changes in the binaries (tested for all of the bootloaders generated by the makeall.* scripts.)

- use avr-gcc 5.4.0 shipped with Arduino 1.8.7 as it's the only one
that supports PB chips
- added new targets (mostly ATtiny chips)
- generate comparison with emoji by default
- update allow_failures

bd451cfa0e fix the windows omake.bat (maybe?) 
get our own copy of https://github.com/WestfW/Arduino-avr-tools-install
and used that to set up the tool paths.  You still need to make "make"
installed in the path (or in the arduino tools bin directory.)

e9af37fef0 Bumb to Version 8.0: add DO_SPM code 
This is not quite the same as MCUdude's code, but it has the same
calling conventions.  This version doesn't use do_spm from the bootloading
code itself, since that recently went to some effort to use more of
the standardized boot.h calls.  That means that this code is a bit
bigger than it really needs to be.  (Still small enough to fit within
the 512byte limit, given recent compilers.)
Sadly, the compiler options that barely fit SUPPORT_EEPROM in 512bytes
are incompatible with DO_SPM, so you have to choose.  Since do_spm was
supported by the MCUDude platforms, and not 512byte version of optiboot
has ever supported EEPROM, the do_spm code wins, for backward compatibility!

Also standardize the "makeall" shell script names, and update the release script.

Fix baud rate setting for single speed mode
 2018-09-05 01:35:10 -04:00
Marco Milanese
97ae2a52f4 Fix baud rate setting for single speed mode 
Baud rate is calculated using the hardcoded formula:
	( (F_CPU + BAUD_RATE * 4L) / (BAUD_RATE * 8L) - 1 )
While this is correct for double speed mode, this value is wrong
for single speed mode and leads to corrupted communications.

The issue is fixed by reusing the BAUD_SETTING value.

b263cada08 Merge in the MCUdude platforms. Don't do baudcheck, and don't warn 
about moderate baud errors, if PRODUCTION is set.  (this reduces
clutter in the output and should make things a bit quicker.
developers are supposed to check all the warnings prior to setting
PRODUCTION)
