[KW36] ConfigTools v8 - Error creating peripherals.c

Hi,

I am using a FRDM-KW36 NXP Board. I am trying to configure some basic things like PIT, CAN, etc.

My IDE is IAR but I use MCUXpresso ConfigTools Version 8.0 to set the pinout, the clock settings and peripherals information. I think that the CAN code create by default with this tool have some errors:

peripherals.c - ConfigTools

/* Message buffer 0 configuration structure */ const flexcan_rx_mb_config_t CAN0_rx_mb_config_0 = { .id = 0x132UL, .format = kFLEXCAN_FrameFormatStandard, .type = kFLEXCAN_FrameTypeData }; static void CAN0_init(void) { FLEXCAN_Init(CAN0_PERIPHERAL, &CAN0_config, CAN0_CLOCK_SOURCE); /* Message buffer 0 initialization */ FLEXCAN_SetRxMbConfig(CAN0_PERIPHERAL, 0, &CAN0_rx_mb_config_0, true); /* Message buffer 1 initialization */ FLEXCAN_SetTxMbConfig(CAN0_PERIPHERAL, 1, true); /* Enable FlexCAN interrupts of message buffers */ FLEXCAN_EnableMbInterrupts(CAN0_PERIPHERAL, 1UL); /* Enable interrupt CAN0_IRQn request in the NVIC. */ EnableIRQ(CAN0_FLEXCAN_IRQN); }

In CAN0_rx_mb_config_0 the id is set to 0x132UL but the correct format should be FLEXCAN_ID_STD(0x123). If I don't change it only detects the 0x000 messages.

In the EnableIRQ it set the variable CAN0_FLEXCAN_IRQN which is an alias of CAN0_IRQn. However, the FLEXCAN_EnableMbInterrupts() interacts withCAN0_MB_IRQn.

Finally, in peripherals.h is defined:

/* CAN0 interrupt vector ID (number). */ #define CAN0_FLEXCAN_IRQN CAN0_IRQn /* CAN0 interrupt handler identifier. */ #define CAN0_FLEXCAN_IRQHANDLER CAN0_IRQHandler

But CAN0_IRQHandler is not the correct handle for this interrupt. It must be CAN0_MB_IRQHandler.

Anyone else have the same problems?
