STM32 GPIO LLD register naming issue Topic is solved

[Thargon]

Hi,

I just encountered a compilation error when calling palIsLineEventEnabledX() using an STM32L476.

The function is defined identically in all three GPIO LLD versions:

Code: Select all

#define pal_lld_ispadeventenabled(port, pad)                                \
  (bool)((EXTI->IMR & (1U << (uint32_t)pad)) != 0U)


Now the issue is, that IMR is not defined for this microcontroller.
Looking up the EXTI_TypeDef struct in the stm32l476xx.h file reveals that there are in fact two register sets, which include IMR1 and IMR2.
A brief search indicates, that there are probably several microcontrollers affected by this:

• STM32F3
• STM32H7
• STM32L4

Can you confirm the issue, or am I missing something here?

Thanks, I need to verify, those headers have a lot of naming differences.

Hi,

Fixed as bug #1051 on trunk and 19.1.4. Could you please verify?
