The port configuration api was not correctly setting the port-pins'
direction. Changed the port driver to call the gpio driver for
configuration (read and write still are optimized for port-level
operations) so that the behavior is consistent.
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.
Corrected nanostack PAE controller
Changes on #11539 conflicted with nanostack changes on master. Removed the duplicated functions from PAE controller.
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.
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.
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.
