flexcan interrupt_transfer demo doesn't run with FLEXCAN1

[CJ-JIN]

Hi guys,

I have tested the flexcan demo project(interrupt_transfer) from SDK package which use flexcan2, it works and print the log information.

But when i changed it from FLEXCAN2 to FLEXCAN1, it blocked at IOMUXC_SetPinMux process.

Default demo code

====================

IOMUXC_SetPinMux(
 IOMUXC_GPIO_AD_B0_14_FLEXCAN2_TX, /* GPIO_AD_B0_14 is configured as FLEXCAN2_TX */
 1U); /* Software Input On Field: Force input path of pad GPIO_AD_B0_14 */
 IOMUXC_SetPinMux(
 IOMUXC_GPIO_AD_B0_15_FLEXCAN2_RX, /* GPIO_AD_B0_15 is configured as FLEXCAN2_RX */
 1U);

My Code

================================================================

IOMUXC_SetPinMux(
IOMUXC_GPIO_AD_B1_08_FLEXCAN1_TX, /* GPIO_AD_B0_14 is configured as FLEXCAN2_TX */
1U); /* Software Input On Field: Force input path of pad GPIO_AD_B0_14 */
IOMUXC_SetPinMux(
IOMUXC_GPIO_AD_B1_09_FLEXCAN1_RX, /* GPIO_AD_B0_15 is configured as FLEXCAN2_RX */
1U);

when I block my code, then it runs and print log information.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I think I need more information about the issue, as you mentioned, whether you mean it will encounter a hardfault error when executing the modified code.
Further, I was wondering if you can introduce the testing process, such as code modification, board, etc
Have a great day,
TIC

Project: flexcan_interrupt_transfer demo from SDK_2.9.3_EVK-MIMXRT1060

Boards: Customized

ICF: flexspi_nor_release

Refer to attached file code_change1 and code_change2 for Code modified.

Test Process:

Case 1: Use demo project with Flexcan2(default)

Using mfgtool to download to target board and it print the log( refer to  attached file log.png) .

Case 2: Use demo project with modified code(Flexcan1)

    step.1 Download to the target board and there is nothing prompt.

    step.2 When block the modified code, then there are log as Case1.
