Previous to this patch the qemu-arm tests were compiled with is_relp=true
meaning that the __repl_print__ function was called for all lines of code
in the outer scope. This is not the right behaviour for scripts that are
executed as though they were a file (eg tests).
With this fix the micropython/heapalloc_str.py test now works so it is
removed from the test blacklist.
With caching of map lookups in the bytecode, frozen bytecode can still
work but must be stored in RAM, not ROM. This patch allows mpy-tool.py to
generate code that works with this optimisation, but it's not recommended
to use it on embedded targets (because of lack of RAM).
Previous to this patch pyboard.py would open a new serial connection to
the target for each script that was run, and for any command that was run.
Apart from being inefficient, this meant that the board was soft-reset
between scripts/commands, which precludes scripts from accessing variables
set in a previous one.
This patch changes the behaviour of pyboard.py so that the connection to
the target is created only once, and it's not reset between scripts or any
command that is sent with the -c option.
To make its inclusion as frozen modules in multiple ports less magic.
Ports are just expected to symlink 2 files into their scripts/modules
subdirs.
Unix port updated to use this and in general follow frozen modules setup
tested and tried on baremetal ports, where there's "scripts" predefined
dir (overridable with FROZEN_DIR make var), and a user just drops Python
files there.
This helps to test floating point code on Cortex-M hardware.
As part of this patch the link-time-optimisation was disabled because it
wasn't compatible with software FP support. In particular, the linker
could not find the __aeabi_f2d, __aeabi_d2f etc functions even though they
were provided by lib/libm/math.c.
Frozen modules are now stored with extensions and with '/' as path
separator. In other words, frozen modules paths stored as they are
in normal filesystem.
When an mpy file is frozen it must know the values of certain
configuration variables. This patch provides an explicit check in the
generated C file that the configuration variables are what they are
supposed to be.
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).
This fix adds PIDs 9801 and 9802 to the pybcdc.inf file.
When in CDC only mode, it presents itself as a Communcations
device rather than as a composite device. Presenting as a
composite device with only the CDC interface seems to confuse
windows.
To test and make sure that the correct pybcdc.inf was being used,
I used USBDeview from http://www.nirsoft.net/utils/usb_devices_view.html
to uninstall any old pyboard drivers (Use Control-F and search
for pyboard). I found running USBDeview as administrator worked best.
Installing the driver in CDC+MSC mode first is recommended (since the
pybcdc.inf file in on the internal flash drive). Then when you switch
modes everything seems to work properly.
I used https://github.com/dhylands/upy-examples/blob/master/boot_switch.py
to easily switch the pyboard between the various USB modes for testing.
The adapter class "TelnetToSerial" is used to access the Telnet
connection using the same API as with the serial connection. The
function pyboard.run-test() has been removed to made the module
generic and because this small test is no longer needed.
When looking for chars to indicate raw repl is active, look for the full
string of chars to improve reliability of entering raw repl correctly.
Previous to this patch there was the possibility that raw repl was
entered in a dirty state, where not all input chars from previous
invocation were drained.
In raw REPL ">" indicates the prompt. We originally read this character
upon entering the raw REPL, and after reading the last bit of the
output. This patch changes the logic so the ">" is read only just
before trying to send the next command. To make this work (and as an
added feature) the input buffer is now flushed upon entering raw REPL.
The main reason for this change is so that pyboard.py recognises the EOF
when sys.exit() is called on the pyboard. Ie, if you run pyboard.py
with a script that calls sys.exit(), then pyboard.py will exit after
the sys.exit() is called.
upip is a simple and light-weight package manager for MicroPython modules,
offering subset of pip functionality. upip is part of micropython-lib
project: https://github.com/micropython/micropython-lib/tree/master/upip
This script bootstraps upip by downloading and unpacking it directly from
PyPI repository, with all other packages to be installed with upip itself.
Replaces RUN_TEST=1 definition; now "make test" in qemu-arm directory
will run tests/basics/ and check that they all succeed.
This patch also enables the test on Travis CI.
We don't have an explicit ChangeLog file, but don't really need one
because we use a good version control system. This script is useful if
you need a pretty-printed ChangeLog for some reason.
This makes pyboard.py much more useful for long running scripts. When
running a script via pyboard.py, it now waits until the script finishes,
with no timeout. CTRL-C can be used to break out of the waiting if
needed.
Improvements are:
2 ctrl-C's are now needed to truly kill running script on pyboard, so
make CDC interface allow multiple ctrl-C's through at once (ie sending
b'\x03\x03' to pyboard now counts as 2 ctrl-C's).
ctrl-C in friendly-repl can now stop multi-line input.
In raw-repl mode, use ctrl-D to indicate end of running script, and also
end of any error message. Thus, output of raw-repl is always at least 2
ctrl-D's and it's much easier to parse.
pyboard.py is now a bit faster, handles exceptions from pyboard better
(prints them and exits with exit code 1), prints out the pyboard output
while the script is running (instead of waiting till the end), and
allows to follow the output of a previous script when run with no
arguments.
-t/--target is a pip option. Trying to use pip options for different meanings
in pip-micropython may lead to big confusion. That's why the original passed
any extra parameters using environment variables. "All options belong to pip."
Using Python's file open in 'r' mode opens it for text reading, which
converts all new lines to \n. Could use 'rb' binary mode, but then
don't have access to the string Template replacement functions. Thus,
force the output to have '\\r\\n' ending.
Also fix regex to match hex digits.
The USB VID&PID are automatically extracted from usbd_desc_cdc_msc.c
and inserted into pybcdc_inf.template, ensuring that the same USB
IDs get used everywhere
