Projects have only ever made use of one linker script per compiler.
However, the tools would store references to multiple linker scripts in
a project and select one in a non-deterministic way. Now we clear out
any existing linker script when we add a new one to a project. This way,
the last added linker script is always used.
The sct file path generated in the online compiler
is incorrect. Fix that by changing the correct_scatter_shebang
API to accept a FileRef object instead and use the path.
This change should go with change in online compiler that removes
the override for correct_scatter_shebang.
For default construction of the driver, it would be necessary to define
the pins. However as we don't know the correct pins, until/unless user
sets them up for us. So it makes sense to mark the pins as NC. It would
be easier to debug if the pins are set to NC if user forgot to set them
up.
To make this driver more useful, we needed to do some changes. The
wirings for the modem can differ on the board so we also need to be
flexible in our approach.
It is now mandatory to provide the power pin and pin polarity in the
constructor alongwith the file handle. Reset pin is optional.
Standard 3GPP TS27.007 states that the AT+CGSN command can optionally
have type parameter that determines the output. However Quiectel EC2X
series doesn't accept parameters. We need to reflect that in the
cellular properties setup.
Provides basic power up / power down sequences for Quectel EC2X series
modems. Can be used in PPP mode. For using the on-board IP stack, we
will need to add and implement classes that provide context.
Driver constructor takes power and reset control pins along with the
FileHandle. A default construction is provided which can be chosen by
the application in its mbed_app.json. Otherwise the user is free to
construct as per demand.
Using malloc will require us to add stdlib.h somewhere in the path for
the application. Maybe the CI apps are adding stdlib.h and that's why
the code would have worked. In a custom app, it can happen that the
header is not included. Using new avoids the need to add stdlib.h
anywhere and it is more in line with C++.
This change moves all PDL drivers into common source and include
directories to alleviate issue with Windows version of GNU Make 4.x
maximum command line length limit.
When zipping up projects, the makefile exporter brings every directory
supplied as --source under the same directory, even if they are in a
parent directory. There was some code that was clearing the leading
"../" components. This lead to an empty string ("") being supplied to
the "into_path" arg for "resources.add_directory". Since "" is not None,
the default behavior to place it in the same directory was not being
used. The extra "" caused a leading "/" to be added, making everything
placed a the absolute root of the filesystem ("/").
Now we check to see if the "into_path" is an empty string and ignore it
if that's the case.
The FileRefs allow you to preserve the correct file paths in the online
compiler. It also allows you to preserve the correct file paths for
generated files.
FastModels are a software simulator for Arm platform/cores.
They mean to be used as a tool for testing or early prototype stage development.
Due to the nature of software simulator can't grantee the timing accuracy like HW.
So time drifting test is skipped for software models.
For single-threaded apps __iar_Initlocks() is not required and must
not be called because the proper IAR library is brought in only if
"--threaded_lib" is defined in the linker command.
