Assistance Required for CAN 1 Configuration on LPC54606J512 MCU

Hello team,

I am working with the LPC54606J512 MCU and am trying to use CAN 1. I have configured the CAN_TD and CAN_RD pins, but I am encountering the error "kStatus_MCAN_ErrorStatus" when transmitting data. Below are the configurations I have changed for CAN 1:

#define USE_IMPROVED_TIMING_CONFIG (1U) #define EXAMPLE_MCAN_IRQHandler CAN1_IRQ0_IRQHandler #define EXAMPLE_MCAN_IRQn CAN1_IRQ0_IRQn #define EXAMPLE_MCAN CAN1 #define MCAN_CLK_FREQ CLOCK_GetMCanClkFreq(1U)

The clock frequency is set to 12 MHz, with the following configuration:

config->baudRateA = 500000U; config->baudRateD = 2000000U; config->enableCanfdNormal = false; config->enableCanfdSwitch = false; config->enableLoopBackInt = false; config->enableLoopBackExt = false; config->enableBusMon = false; /* Default protocol timing configuration, time quantum is 16. */ config->timingConfig.seg1 = 0xAU; config->timingConfig.seg2 = 0x3U; config->timingConfig.rJumpwidth = 0x3U;

Could you kindly guide me in resolving this issue.

Thanks & regards,
Amit Sutrave

Hi @amit_sutrave77

First, you should check the Hardware Connections and Verify Clock and Baud Rate Configuration.

And then I think you can try a simple internal loopback test to confirm that CAN transmission and reception work without a transceiver.

Use an oscilloscope or logic analyzer to check if CAN_TD is sending data.

Capture error codes from the CAN error status registers.
