KSDK2.0 EDMA_HandleIRQ callback calls NULL

[manfredschnell]

Hello,

we use KSDK2.0 with K64.

In Function EDMA_HandleIRQ() "fsl_edma.c" the handle->callback() is called regardless if it's NULL. --> This leads to HardFault.

The "Kinetis SDK v.2.0 API Reference Manual.pdf" on page 221 writes relating to that:

"16.7.38  void EDMA_HandleIRQ (edma_handle_t *  handle )

This function clears the channel major interrupt flag and call the callback function if it is not NULL."

Next KSDK source should be changed to call the callback only, if it's not NULL.

Best regards

Manfred

Manfred,

I've confirmed that this code is updated already and will be available in the next release of the edma driver enabled parts.

if ((handle->tcdPool == NULL) && (handle->callback != NULL))
    {
        (handle->callback)(handle, handle->userData, true, 0);
    }
/* Invoke callback function. */
        if (handle->callback)
        {
            (handle->callback)(handle, handle->userData, transfer_done, tcds_done);
        }

Thanks for your feedback,

Jason
