Nicla Voice 🗣️

Full Changelog: https://github.com/arduino/ArduinoCore-mbed/compare/3.5.4...3.5.5

New target

GIGA R1 WiFi 🔥

What’s Changed

• Based on mbed-os-6.17.0
• Nicla Voice firmwares update
• Nicla Vision bootloader update
• Portenta H7 fix SecureQSPIFBlockDevice initialization
• Enable M4 on all supported boards [1]
• SDRAM fix PLL settings

[1] M4 core on supported boards can now be enabled from a submenu that will appear after selecting the target board (Portenta H7, Nicla Vision, Opta or Giga)
If you were using any of these boards in a CI, the fqbn is unchanged (the extra field is filled with default values by default).
However, if you were targeting “Portenta H7 M4”, you’ll need to change the fqbn into arduino:mbed_portenta:envie_m7:target_core=cm4

Bugfixes / improvements

• Fix analogRead() for STM32H7 boards using HSI clock
• Increased quantity of WiFi AP scanned and managed for connection
• STM32H7: Add function to get reset reson and read/write RTC backup registers
• Nicla: tune battery charger
• GSM: modify begin() to allow setting bands
• USB: allow populating VID/PID dynamically
• RP2040: add USBMSD binding to SFU (OTA update) only if included explicitly

Full Changelog: https://github.com/arduino/ArduinoCore-mbed/compare/3.4.1...3.5.4

What’s Changed

This release contains some fixes specifically for Portenta H7.

If you need precise timekeeping please update the bootloader to v24 with this sketch: https://github.com/arduino/ArduinoCore-mbed/tree/master/libraries/STM32H747_System/examples/STM32H747_manageBootloader
The core will then recognize the right bootloader version at startup and will enable the precise RTC clock source.
Keep in mind that RTC timekeeping is not supoorted in VBAT mode at the moment due to hardware limitations.

Other notable fixes:

• Thales/GPS: fix hang when end() is called
• WiFi: Fix crash on disconnect() if already disconnected.
