Hi,
If you are interested I perform the port of Ada runtime library and the demo_leds example. As Jerry wrote the RCC module is a little bit different on the STM32F42x and the origin of the problem came from the voltage scaling operation during initialization.
The main modifications were:
- PLL configuration,
- Add of the 9 new interrupt sources,
- Link command files,
- USART1 configuration update (from GPIOB to GPIOA).
For recall the pins are:
- LED3: PG13,
- LED4: PG14,
- USART1_TX: PA9,
- USART2_RX: PA10.
The LEDs and user button work correctly but I do not test the USART1 yet because I have no TTL<->RS232 converter.
The files are available on GitHub:

Regards,
Gnops
