Patches generated from https://github.com/arduino/mbed-os/tree/extrapatches-6.15.1 (over mbed-os 6.15.1)
Core fixes
Make pinMode() always reconfigure gpio if called explicitly
Fix the preprocess linkerscript (thanks @rajames)
SocketWrapper: UDP: send packet on endPacket(), not on write()
Fix calling ::flush() on SerialUSB
Serial: drop characters if the ringbuffer is full
Added rules for pluggable discoveries and monitors
Targets improvements
Add RP2040 RTC and Watchdog patches
RP2040: use proper fix for usb_device_enumeration
Nicla Sense ME:
- Update bootloader binaries
- Added defines for internal pins
Libraries fixes
WiFi: fix linking inherited macAddress()
Portenta: PDM: cut out unusable starting PDM sample
Portenta: PDM: use PLL3 to clock SAI
PR2040: Disable DMA_IRQ_0n when stopping PDM peripheral
lvgl: add compatibility layer for both v7 and v8
Libraries improvements
Modernize all the libraries
Fix incorrect/misleading library.properties
Add a ton of examples
Portenta: RPC library is now out of beta
New targets!
Arduino Nicla Sense ME
Libraries
WiFi: Fix Access Point teardown on Portenta
Camera: enable 320x320 resolution
PDM: fix restart on RP2040
Core
Update mbed-os to 6.15.0
Portenta: add menu to configure non standard flash splits between M7 and M4
RP2040: optimize RAM usage
RP2040: fix flash size in linker script
Core
Rebuild variants on mbed 6.13
RP2040: support led indication when the core crashes
Libraries
PDM: fix glitches RP2040
Networking: introduce SocketWrapper library and derive WiFi/Ethernet from it
This makes much easier to port any networking class to Arduino APIs
SocketWrapper: make available() non blocking
Bootloaders
Update Nano33BLE updateBootloader sketch
Core
Rebuild variants on mbed 6.12
analogWrite() for Portenta doesn't crash anymore on HRTIM pins (eg. pin 3).
- The default frequency of the PWM on such pins is 720Hz
Serial: properly protect ringbuffer access
Libraries
PDM: fix gain on RP2040
WiFi: refactor to match new mbed-os APIs
Extra
Restore functionality as mbed library (sample project in the comment here )
Core
Allow UART constructors in both PinName and pin number
Fix Arduino.h inclusion in C files
Nano33BLE: Fix pins 0 / 1 not usable as GPIOs
RP2040: fix watchdog behaviour
RP2040: avoid implicit conversion from NinaPin to int (LEDR, LEDG, LEDB) [1]
Libraries
Add Nano33_updateBootloader sketch to support SoftDevices
PDM: Correct default gain for Portenta
PDM: Run clock at 2.08MHz on RP2040
Fix OTA second stage bootloader for Nano RP2040 Connect (SFU)
Examples
MultipleBlinks: fix Nano RP2040 Connect build
[1]
These leds are connected to the ESP32 module, so using them in digitalWrite() is transparent unless the values are cast to int.
In this case, an explicit error will be raised, explaining how to fix the problem,
Core
RP2040: improve the overall user experience
RP2040: fix some relevant bugs (complete list here https://github.com/ARMmbed/mbed-os/pull/14488/commits)
USBSerial: speedup operations and tackle corner cases
Libraries
PDM: rationalize gain() and buffer size
Ethernet: fix library discovery on case insensitive platforms
Wire: fix I2C scan
Extra
Update openocd to its latest release (fixes a bug with nRF52)
