L4 does not have UART6, and has similar registers to the F7.
Original patch was authored by Tobias Badertscher / @tobbad, but it was
reworked to split UART edits from USB edits.
64-bit integer division brings a dependency on library functions. It is
avoided here by dividing fck and baud by a common divisior. The error
is the better (1/(2*0x300)) as with 64 bit division (1/(0x300)).
These files come from STM32Cube_FW_L4_V1.3.0, with Windows line endings
converted to unix. Only basic HAL files are added. In addition the QSPI
support is included to support later external QSPI flash as mass storage.
- add template rule that converts a specified source file into a qstring file
- add special rule for generating a central header that contains all
extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
variable. Each platform appends a list of sources that may contain
qstrings into a new build variable: SRC_QSTR. Any autogenerated
prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.
- remove most qstrings from py/qstrdefs, keep only qstrings that
contain special characters - these cannot be easily detected in the
sources without additional annotations
- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
stmhal, teensy, unix, windows, pic16bit:
- remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
- remove all port specific qstrdefs except for special strings
- append sources for qstr generation in platform makefiles (SRC_QSTR)
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).
tools/pydfu.py is now the recommended way of deploying a DFU file. Old
behaviour of dfu-util can be obtained by passing USE_PYDFU=0 when invoking
make.
The main README.md file has been updated to reflect this change.
If None was returned for such requests (which likely means that user simply
didn't handle them), it means successful init and default sector size of 512
bytes respectively. This makes only BP_IOCTL_SEC_COUNT a mandatory request,
and thus re-establishes parity with old interface, where only .count() is
mandatory().
