hartmannathan opened a new pull request #4214:
URL: https://github.com/apache/incubator-nuttx/pull/4214


   ## Summary
   
   arch/arm/src/stm32/hardware/stm32_exti.h: Change `STM32_EXTI2_OFFSET` (offset to EXTI2 registers) from 0x18 to 0x20. This symbol is defined when `CONFIG_STM32_STM32F30XX` or `CONFIG_STM32_STM32F33XX`. According to the current reference manuals for STM32F334xx (RM0364 rev 4) and STM32F302xx (RM0365 rev 8), EXTI_IMR1 is at offset 0x00 and EXTI_IMR2 is at offset 0x20, i.e., 0x20 apart. The same offset applies to the rest of the registers: EMR1/EMR2, RTSR1/RTSR2, etc.
   
   ## Impact
   
   Will affect all uses of EXTI2 on all STM32F30xx and STM32F33xx family SoCs.
   
   ## Testing
   
   **None**: Unfortunately I do not have hardware available to test this change.
   
   I could not find a STM32F30 or STM32F33 for which the RM documents a 0x18 offset; however if I missed a P/N where this is the case, please let me know.
