Bug in MCUXpresso's FlexCAN driver

EmbeddedExpertise — Wed, 01 Jun 2022 13:02:09 GMT

Hello supporters,

At the very bottom of fsl_flexcan.c there is this:

#if defined(FLEXCAN2)
void CAN_FD2_DriverIRQHandler(void)
{
    assert(NULL != s_flexcanHandle[2]);
    s_flexcanIsr(FLEXCAN1, s_flexcanHandle[2]);
    SDK_ISR_EXIT_BARRIER;
}
#endif

I think there is a mix-up between FLEXCAN1 and FLEXCAN2, higlighted in red. I'd appreciate your confirmation.

Thank you.

Best regards,

Thierry-

Can you please clarify which board and device are you using? And the SDK version

The SDK where the bug initially showed up is version 2.9. I double-checked that the bug is still present in the latest version 2.11.1, archive file SDK_2.11.1_MIMX8ML8xxxLZ.zip. Please see file SDK_2_11_1_MIMX8ML8xxxLZ\devices\MIMX8ML8\drivers\fsl_flexcan.c, line 4638.

The device is an i.MX8M-Plus. The reported bug is believed to be board-independent. Just for your reference, the board is a BoundaryDevices SoM with a custom carrier.

Best regards,

I just downloaded SDK_2_13_0_MIMX8ML8xxxKZ (latest & greatest 01.2023) and the reported bug is still present! I wonder how this driver is tested at NXP!?
