In my application I use the TMS570havgsd. This communicates with an external transceiver. Over SPI4 port the messages are sent out and over MibSPI5 the data packages are to be received. It concerns 6 x 8 bit data packets. As soon as a data packet arrives, an interrupt should come and the data should be read out of the MibSPI receive buffer and copied into a queue so that they can be read out in another function.
The communication works quite well so far. Except for very few cases, where no interrupt comes. What could be the reason for an interrupt not arriving?
On the oscilloscope I see the complete message. So it is not up to the external transceiver device.
I would very much appreciate your support.
