  • Mailbox issue


    We are working with the Renesas RZ/A1H platform and we use mailboxes to store structure type messages which are 256+ Bytes long.
    The size of the mailbox is 50 elements.

    The application runs for an hour then hangs at line 'UserAbortHandler' in JLINKDCC_HandleDataAbort.S

    The stacks sizes are defined as follow in .LD File:

    FIQ_STACK_SIZE = 0x0;
    IRQ_STACK_SIZE = 0x0100;
    ABT_STACK_SIZE = 0x0100;
    UND_STACK_SIZE = 0x0;
    SVC_STACK_SIZE = 0x0400;

    _Min_Heap_Size = 0x4000;

    Could you explain how to define the stacks sizes ?

  • Hello Vincent,

    there could be different reasons for the fault but this must not be related to the stacks.
    The stack sizes look ok but they depend on the actual application.
    When you are in support you can also contact us directly and we will help you to investigate the issue.

    Best regards,
