TMS320F2800157: F280015x MCAN examples - interrupt problem

Part Number: TMS320F2800157


Hello,

I tried to use following examples in my F280015x Series LaunchPad Development Kit:

  • mcan_ex4_receive
  • mcan_ex10_receive_multiple_buffers

Problem is that the ISR MCANIntr1ISR() can only be hit once after start-up (message is properly received in buffer).

To be able to receive another CAN message I need to restart the debug session.

In SW I only changed GPIO ports to GPIO_5/GPIO_4, so that it works.

What is the reason?
