FDCAN On STM32H563 Topic is solved

[Emara]

Hi! Is FDCAN fully supported on STM32H563??
I didn't find the FDCAN ISRs in stm32_isr.inc of the stm32h563, is it not fully supported or defined somewhere else?

[Giovanni]

Hi,

It is supported, ISRs are in those stm32_fdcanN.inc files.

Status is unknown, it has been tested on G4 and H7 so far.

HI!
FDCAN Handlers are not linked to its vectors there, Had to add it manually to stm32_isr.inc

Code: Select all

#define STM32_FDCAN1_IT0_NUMBER             39
#define STM32_FDCAN1_IT1_NUMBER             40
#define STM32_FDCAN2_IT0_NUMBER             109
#define STM32_FDCAN2_IT1_NUMBER             110
#define STM32_FDCAN1_IT0_HANDLER            VectorDC
#define STM32_FDCAN1_IT1_HANDLER            VectorE0
#define STM32_FDCAN2_IT0_HANDLER            Vector1F4
#define STM32_FDCAN2_IT1_HANDLER            Vector1F8

Hi,

Thanks for finding, I committed the change on trunk.

Hi! thanks for the update, also in stm32_isr.c fdcan irqs need to be initialized in irqInit()

Code: Select all

  fdcan1_irq_init();
  fdcan2_irq_init();

and in irqDeinit()

Code: Select all

  fdcan1_irq_deinit();
  fdcan2_irq_deinit();

[Giovanni]

Forgot about that, committed.

Hi,
Regarding the same file stm32_isr.h for the STM32H563, I believe there may be a minor naming issue in the following definition:

Code: Select all

#define STM32_TIM1_UP_TIM16_NUMBER 42

It seems this should instead be:

Code: Select all

#define STM32_TIM1_UP_NUMBER 42

Hi,

Changes committed, thanks.
