Tool/software:
Hi Experts,
I am asking for my customer here. This is urgent issue from customer's side.
They found SCI communication failure between F280039C-Q1 and F280039C-Q1. They used a 1ms timer to complete SCI communication through state machine.
#. When one F280039C-Q1 project Enable “Don’t generate RPT instructions”, The 1ms task will be prolonged, resulting in a long period of no response to the communication data sent by the host.
(CH2 is SCI RX, CH3 is GPIO Toggle waveform of 1ms Timer state machine)
#. When one F280039C-Q1 project disable “Don’t generate RPT instructions”, The 1ms task will be normally as below figure, SCI communication normally.
(CH2 is SCI RX, CH3 is GPIO Toggle waveform of 1ms Timer state machine). The customer claims and tests that the 80K interrupt is normal, and there is only one PWM_ISR interrupt in the program. Could you give us guide or dir./suggestion here? Thanks.
