STM32L432, STM32L433 and STM32L443 HAL port issues

Postby zmolnar » Wed Mar 06, 2019 10:43 am


I discovered two possible issues in the HAL port of STM32L432, STM32L433 and STM32L443 micros:

1. it uses GPIOv3 driver. This might be wrong, as these micros don't have ASCR. (page 274)
2. In the config of STM32L433 MCU SPI2 and I2C2 are disabled although they do exist in the controller (page 61-62)

STM32L41xxx/42xxx/43xxx/44xxx/45xxx/46xxx advanced Arm®-based 32-bit MCUs

I'm using this version:

Code: Select all

If you can confirm, that these are real issues, later on I can provide you patches as well, but I don't have boards to test it.

Apparently ST dropped this ASCR register for newer devices, it is not present in the new G0 and L5 families.

GPIOv3 can work when the register is not present, any write there is harmless. Still thinking to a full solution.
