It seems the GPIOH and GPIOD enable mask are not set for STM32L422.

As seen here in the github mirror:
m

Please enable them

Code to fix the issue below:
#define STM32_GPIO_EN_MASK (RCC_AHB2ENR_GPIOAEN | \
RCC_AHB2ENR_GPIOBEN | \
RCC_AHB2ENR_GPIOCEN | \
RCC_AHB2ENR_GPIODEN | \
RCC_AHB2ENR ...

Hi Giovanni,

Thanks, just tested. Works now.

Thanks,

D and E ports should also be enabled for the larger pin variants (64 and 100 pins)

Upon further inspection, the L433 and L443 have the exact same set of peripherals. The only difference being that L443 has the hash/crypto function.

This was found in RM03943 Rev 4, page 61 of 1600.

Therefore the define for STM32L433xx on line 79
#if defined(STM32L432xx) || defined(STM32L433xx ...

Should STM32L433 and STM32L432 potentially be split?

L433 has one extra i2c and also one extra spi peripheral compared to L432.

The STM32L433 has GPIOH pins included and are disabled as this chip is defined together with STM32L432 which doesn't have GPIOH pins

This can be fixed with a #define check in to enable GPIOH pins for STM32L433.

Thanks,
Xelus
