The nrf52840-mdk-usb-dongle and pca10050 comes with a pre-flashed
bootloader (OpenBootloader).
This commit updates the boards "mpconfigboard.mk" to use DFU as
default flashing method and set the corresponding BOOTLOADER
settings such that nrf52840_open_bootloader_1.2.x.ld linker
script is used.
The default DFU flashing method can be disabled by issuing "DFU=0"
when invoking make. This will lead to "segger" being used as default
flashing tool. When using "DFU=0", the linker scripts will not
compensate for any MBR and Bootloader region being present, and might
overwrite them if they were present.
The commit also removes the custom linker script specific to
nrf52840-mdk-usb-dongle as it now points to a generic.
Updated nrf52840-mdk-usb-dongle's README.md to be more clear on
how to deploy the built firmware.
The port README.md has also been updated. In the list of target
boards a new column has been added to indicate which bootloader
is present on the target board. And for consistency, changed all
examples in the README.md to use "deploy" instead of "flash".
An additional Makefile parameter NRFUTIL_PORT can be set in order
to define the serial port to used for the DFU (Default: /dev/ttyACM0).
The "nrfutil" that is used as flasher towards OpenBootloader is
available for installation through Python "pip".
In case of SD=s140, SoftDevice ID 0xB6 is passed to nrfutil's package
generation which corresponds to SoftDevice s140 v6.1.1.
Add the option for "mpconfigboard.mk" to define whether the
board hosts a bootloader or not. The BOOTLOADER make variable
must be set to the name of the bootloader.
When the BOOTLOADER name is set it is also required to supply
the BOOTLOADER_VERSION_MAJOR and the BOOTLOADER_VERSION_MINOR
from the "mpconfigboards.mk". These will be used to resolve which
bootloader linker script that should be passed to the linker.
The BOOTLOADER section also supplies the C-compiler with
BOOTLOADER_<bootloader name>=<version major><version minor>
as a compiler define. This is for future use in case a bootloader
needs to do modification to the startup files or similar (like
setting the VTOR specific to a version of a bootloader).
Adding variables that can be set from other linker scripts:
- _bootloader_head_size:
Bootloader flash offset in front of the application.
- _bootloader_tail_size:
Bootloader offset from the tail of the flash.
In case the bootloader is located at the end.
- _bootloader_head_ram_size:
Bootloader RAM usage in front of the application.
Updated calculations of application flash and RAM.
Two issues are tackled:
1. The calculation of the correct length to print is fixed to treat the
precision as a maximum length instead as the exact length.
This is done for both qstr (%q) and for regular str (%s).
2. Fix the incorrect use of mp_printf("%.*s") to mp_print_strn().
Because of the fix of above issue, some testcases that would print
an embedded null-byte (^@ in test-output) would now fail.
The bug here is that "%s" was used to print null-bytes. Instead,
mp_print_strn is used to make sure all bytes are outputted and the
exact length is respected.
Test-cases are added for both %s and %q with a combination of precision
and padding specifiers.
The zephyr function net_shell_cmd_iface() was removed in zephyr v1.14.0,
therefore the MicroPython zephyr port did not build with newer zephyr
versions when CONFIG_NET_SHELL=y. Replace with a more general
shell_exec() function that can execute any zephyr shell command. For
example:
>>> zephyr.shell_exec("net")
Subcommands:
allocs :Print network memory allocations.
arp :Print information about IPv4 ARP cache.
conn :Print information about network connections.
dns :Show how DNS is configured.
events :Monitor network management events.
gptp :Print information about gPTP support.
iface :Print information about network interfaces.
ipv6 :Print information about IPv6 specific information and
configuration.
mem :Print information about network memory usage.
nbr :Print neighbor information.
ping :Ping a network host.
pkt :net_pkt information.
ppp :PPP information.
resume :Resume a network interface
route :Show network route.
stacks :Show network stacks information.
stats :Show network statistics.
suspend :Suspend a network interface
tcp :Connect/send/close TCP connection.
vlan :Show VLAN information.
websocket :Print information about WebSocket connections.
>>> zephyr.shell_exec("kernel")
kernel - Kernel commands
Subcommands:
cycles :Kernel cycles.
reboot :Reboot.
stacks :List threads stack usage.
threads :List kernel threads.
uptime :Kernel uptime.
version :Kernel version.

The -Og optimisation level produces a more realistic build, gives a better
debugging experience, and generates smaller code than -O0, allowing debug
builds to fit in flash.
This commit also assigns variables in can.c to prevent warnings when -Og is
used, and builds a board in CI with DEBUG=1 enabled.

Even though IRQs are disabled this seems to be required on H7 Rev Y,
otherwise Systick interrupt triggers and the MCU leaves the stop mode
immediately.
This commit saves OSCs/PLLs state before STOP mode and restores them on
exit. Some boards use HSI48 for USB for example, others have PLL2/3
enabled, etc.
Rather than dealing with the different int types, just pass them all as a
single array of mp_int_t with n_unsigned (before addr) and n_signed (after
addr).

This adds `_IRQ_GET_SECRET` and `_IRQ_SET_SECRET` events to allow the BT
stack to request the Python code retrive/store/delete secret key data. The
actual keys and values are opaque to Python and stack-specific.
Only NimBLE is implemented (pending moving btstack to sync events). The
secret store is designed to be compatible with BlueKitchen's TLV store API.

This widens the characteristic/descriptor flags to 16-bit, to allow setting
encryption/authentication requirements.
Sets the required flags for NimBLE and btstack implementations.
The BLE.FLAG_* constants will eventually be deprecated in favour of copy
