The `sleep` function as been changed into `hal_sleep` by #3607.
Unfortunately the call to `sleep` in the hal_patch for the NRF51822 has not been
updated to `hal_sleep`. The result was a link time error for targets based on
NRF51822_LEGACY compiling with the mbed OS 5 tree.
An earlier patch in this series changed the API for
`build_api.prepare_toolchain`. This commit updates the `find_test`
function to call `prepare_toolchain` correctly.
An earlier patch in this series relies on the assumption that all
toolchain construction goes through `prepare_toolchain`. This is still
not the case. The only remaining user of the `mbedToolchain` object that
does not go through `prepare_toolchain` is the static analysis scanner.
It's basically dead-code at this point. I say we remove it. So this
patch removes it.
The prior patch in this series makes the assumption that any building
will go through `build_api.prepare_toolchain`. This was not a valid
assumption for the mbed2 build process. So, instead of maintaining 2
ways of using the toolchain classes, I elected to unify on
`prepare_toolchain`.
If the free memory on a device is small enough then the calculation to
determine heap size could underflow to a large value. If this happens
then malloc will never return failure and instead will cause a crash on
allocation. This patch prevents the underflow so malloc works as
expected even with low amounts of free memory.
This is a bug fix for the following bug (Github issue #437):
If two builds were run specifying a non-default build folder, the second
build would fail to link with duplicate symbols and may not fit on the
device. The root of this problem is that these non-default build folders
are not ignored by scan-resources, and therefore included in the build.
We fix this bug by ignoring the build directory passed into the tools.
We have scripts (written in python) that are run after a binary image is
created in the tools. These scripts are not really exportable, as they
are part of the tools and may include and use any bits of python code
they please. So we don't export them. This patch disables export
combinations that would not work because the post-binary hook is not
exported. A white-list is used for forward compatibility.
Recently the Keil IDE has released version 5.23. This version requires
the FPU to be set as part of the <Cpu> tag in the .uvprojx (XML project
file). This patch adds the appropriate FPU settings based on the
trailing F (FPU enabled) or FD (Double precesion FPU enabled) string of
the core.
In case the selected frequency is higher than the requested one, it is
better to send a debug warning rather than an blocking error.
In case of such warning, user may need to redefine the clock tree setting
at higher level (reducing peripheral's input clocks during init phase).
