The generic approach of calling avrdude to perform a reset with `make reset`
does also work on board with a bootloader, but only if no other process is
also accessing the serial (e.g. via `make term`). `make test` first accesses
the serial and then performs `make reset` to not miss any output on the serial.
This however blocks when `make reset` also wants to access that serial.
As workaround, `make reset` is no only provided if the ATmega device is not
programmed via bootloader. Normally, those boards reset anyway upon `make term`,
which allows `make test` to work normally again.
miniterm.py is a simple terminal program that is included with pyserial.
This means that it is available wherever pyterm can work. It allows raw
access, does line translation and passes through special characters.

In order to flash AVR devices, avrdude needs the ability to reset them:
Those using a bootloader will only enter it after a reset, and those programmed
via ISP also need a reset to enter ISP mode.
Sadly, avrdude has no option to reset the board. But running it without commands
will read and print the boards identification and fuse settings. For this, as
reset is needed. This commit uses this side-effect reset to implement make reset
for all AVR based boards
- Move serial.inc.mk in mega-xplained/Makefile.include after
PROG_DEV so PROG_DEV can still default to PORT
- Add deprecation warning for arduino-leonardo and mega-xplained
By ensuring the PORT auto-detection worked, we can give meaningful
error messages and fail earlier.
This uses ensure_value from makefiles/utils/checks.mk. An include was
added to Makefile.include to make this fuction available to all other
makefiles.
This script can detect [Black Magic Probes](https://github.com/blacksphere/blackmagic/wiki) and act as a flashloader (and more).
It is compatible with Linux and macOS.
All important options that can be set via the monitor command are available as arguments.
Makefiles for using `make flash`, `make erase`, `make debug` and `make term` with the script are included.
This commit overrides the default flash recipe with an edbg specific
one.
The new recipe first verifies the flashfile agains the device flash. If
it is already on there, it won't get overridden.
edbg takes care of resetting the device in any case.
pic32prog is a program for flashing pic32 boards from command line on Linux.
It works with:
* Microchip PICkit2
* Microchip PICkit3 with script firmware.
* Other ones: https://github.com/sergev/pic32prog/wiki
Add a variable for `pyterm` specific flags that are not handled by other
terminals.
This will prevent issues with boards that have options only supported by
`pyterm` and setting `pyterm` options from the environment.
This variable is only used for the term recipe (and maybe for flashing). They
should not be evaluated if they are not needed and the user should not see a
warning that the port is not set if he does not use port (for example in make
all.)
DEBUGGER/DEBUGGER_FLAGS/DEBUGSERVER/DEBUGSERVER_FLAGS are evaluated by the
main Makefile.include or by file included by it.
Their value does not need to be exported.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`git show --stat` reports `55 insertions(+), 55 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
RESET and RESET_FLAGS are evaluated by the main Makefile.include or by file
included by it. Their value does not need to be exported.
This will also prevent evaluating 'PORT' for RESET_FLAGS when not needed.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`git show --stat` reports `24 insertions(+), 24 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
FLASHER and FFLAGS are evaluated by the main Makefile.include or by file
included by it. Their value does not need to be exported.
This will also prevent evaluating 'PORT' for FFLAGS when not needed.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`git show --stat` reports `84 insertions(+), 84 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
In UniFlash 4.4.0 the directory where 'xds110reset' is changed.
Try to use the newest one available. If none is found in UNIFLASH_PATH,
try to use one from the PATH to be sure to have a value.
