Arduino AVR Boards 1.6.11 added the {upload.verify} property to the tools.avrdude.upload recipe and {program.verify} to the tools.avrdude.program recipe to support the File > Preferences > Verify code after upload setting.
In Arduino IDE versions 1.6.8 and previous upload.verify is set to true or false depending on the preferences setting which causes Upload to an AVR board with Arduino IDE 1.6.8 or older and Arduino AVR Boards 1.6.11 or newer to generate AVRDUDE commands like:
avrdude -CC:\Users\per\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino2/etc/avrdude.conf -v true -patmega328p -carduino -PCOM21 -b115200 -D -Uflash:w:C:\Users\per\AppData\Local\Temp\buildece560c1024a4a94b7c3b05be61aa2fc.tmp/sketch_sep28a.ino.hex:i
program.verify is unset, which causes Upload Using Programmer to an AVR board with Arduino IDE 1.6.8 or older and Arduino AVR Boards 1.6.11 or newer to generate AVRDUDE commands like:
avrdude -CC:\Users\per\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino6/etc/avrdude.conf -v {program.verify} -patmega328p -cusbasp -Pusb -Uflash:w:C:\Users\per\AppData\Local\Temp\build77ff2e21c5523c5895e8d065447461cb.tmp/sketch_sep28a.ino.hex:i
AVRDUDE 6.0.1 is able to ignore the spurious item in the command and successfully upload but when used with AVRDUDE 6.3.0 this causes upload to fail:
avrdude: no programmer has been specified on the command line or the config file
Specify a programmer using the -c option and try again
This means that Arduino AVR Boards 1.6.12 and 1.6.14 are not backwards compatible with Arduino IDE 1.6.8 and previous.
Setting a default empty value for the upload.verify and program.verify properties in platform.txt causes Arduino IDE 1.6.8 and older to generate an AVRDUDE command identical to that generated with Arduino AVR Boards 1.6.10 or older(meaning that, as previously, the preferences setting has no effect):
avrdude -CC:\Users\per\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino2/etc/avrdude.conf -v -patmega328p -carduino -PCOM21 -b115200 -D -Uflash:w:C:\Users\per\AppData\Local\Temp\buildece560c1024a4a94b7c3b05be61aa2fc.tmp/sketch_sep28a.ino.hex:i
Arduino IDE 1.6.9 and newer overrides the default values of upload.verify and program.verify, therefore this change has no effect on the AVRDUDE command generated and verification is controlled by the preferences setting as usual.
Tested back to Arduino IDE 1.6.2, the oldest IDE version that supports Boards Manager updates.
Previously, during the build, the full package_index.json was downloaded
and distributed with the Arduino IDE.
This lead to a situation where it was difficult to test new AVR cores
before publishing them to the public package_index.json.
Now the bundled AVR core is specificed in the file:
`hardware/package_index_bundled.json`
this index is loaded from the IDE at startup and the package_index.json
is overlayed on it.
This should also solve part of #5143 (Repeatable builds and snapshots of
package/library indexes)
On Linux, setting autosuspend_delay_ms to N and control to auto allows the host pc to suspend the peripheral. Some Linux distro (Ubuntu, Mint) apply this behaviour by default.
If the sketch's prints where less frequent than N milliseconds the sketch prints would never arrive.
This patch allows sending a remote wakeup event to unsuspend the peripheral and allow the serial prints to be received.
to allow WebUSB development, provide a way to change the USB_VERSION reported
using an additional core.
The additional (webUSB) core will survive IDE and AVR core updates
