TDA4VM: MCAN driver with RTOS QNX

Part Number: TDA4VM

Hello,

      When I develop the MCAN driver with QNX, every time I triggered the MCAN interrupt ,the system will hang even the ISR return immediately. 

      But other drivers work normally such as i2c ,devb emmc.

      Is there any different about irq between MCAN and i2c?

      The GIC from 0~960 are all initialed in the intrinfo().   Is there any other more options for the GIC156~158?

THX

    Hi,

    Thanks for the question, but further details, code examples, will be required to address the question.

    If the ISR is firing, that seems like good progress. What are the actions that will take place, as a result of the interrupt firing, and the ISR handler running.  Could these resulting actions be contributing to the hang?

    Regards,
