Update to follow the same `goto exit_point` pattern that is used
by the rest of the functions to avoid leaving the mutex locked
when errors are detected and require the function to abort.
- Use a switch statement rather than shifting and masking to compute
the AlternateBytes value.
- Rename rounded_size to alt_bytes to clarify its purpose.
Existing code may a dependency on the old behavior of "-1" to
mean "no instruction". Therefore, update the typedef, and the value
of QSPI_NO_INST, to avoid breaking those uses.
Encourage the usage of consistent types (there are currently
a mix of `int` and `unsigned int` used for qspi instructions)
QSPI commands are limited to 8 bits, to this is a typdef to char
- Fixed miscalculation in SPI frequency setup (divider value).
- Added possibility to set up SCK line as NC (usable when SPI peripheral
is used to handle non-SPI protocols.
- Fixed handlingh of 16-bit (and other >8 bit) transfers.

The TC flag is used in function serial_is_tx_ongoing to check if there is
an ongoing serial transmission. So this Flag must not be cleared at the
end of the transmission, otherwise, serial_is_tx_ongoing will notify that
TX is ongoing.
The impact is that it may prevent deep sleep to be entered.
Also there is no need to clear this flag at the end of the transaction
because it will be cleared automatically by HW when a new transmission
starts.
It is possible to temporarily suspend USB and safely preserve its
configuration. This is needed to allow a device to enter deep
sleep as a USBDevice instance prevents deep sleep. USB operation can be
suspended with `deinit` and restored with `connect`.
Add 2 targets for DISCO_H747I dualcore:
* DISCO_H747I -> for CM7 core
* DISCO_H747I_CM4 -> for CM4 core
Current restrictions:
* TICKLESS deactivated
* DeepSleep not supported (DeepSleep wrapped to sleep)
Warning: use of the same IP (example I2C1) by both core at the same time is not prevented,
but is strongly not recommended.
Some Hardware Semaphore are use for common IP, to manage concurrent access by both cores: Flash, GPIO, RCC.
Warning: Drag and drop of binary to DISCO_H747I will flash CM7.
In order to flash CM4, one can use STM32 CubeProgrammer tool.
AT_CellularContext::do_connect() is a virtual API and therefore can be overwritten in
inherited class. The problem was that it sets AT_CellularContext::_is_connected flag but
earlier it was set as private member making it impossible to set in overwritten do_connect()
method.
This commit fixes the problem by changing _is_connected as protected enabling its use
in inherited class.
Problem Statement:
During multicast join sequence, InternetSocket::join_multicast_group() calls InternetSocket::modify_multicast_group(). modify_multicast_group() sets up the multicast group address (i.e., mreq.imr_multiaddr) to be joined and the interface address (i.e., mreq.imr_interface) to be used for the multicast join request. The interface address is initialized with the default value, which sets the version of interface address to NSAPI_UNSPEC. This results in LWIP::setsockopt() API to attempt IPv6 multicast join on the IPv4 interface address, hence IPv6 multicast join always fails with the protocol error.
Fix:
Initialize interface address version based on the multicast address version in LWIP::setsockopt(), before attempting multicast join operation.
The cyhal_spi_send api was changed to read and discard a byte on every
send operation (at the protocol level all SPI transfers are bidirectional).
This means that to achieve a truly bidirectional transfer, the
cyhal_spi_transfer API must be called (as opposed to a write followed
by a read).
Earlier changes introduced a change to default Arm C6, which does not compile the micro library which is based on Mbed 2. This change fixes the compiler version for NRF51_MICROBIT devices.
