RTOS SCI/UART using F28069

Andrew Butler

I am trying to use the BIOS based way of triggering a SCI/UART RX interrupt. However, the SCI_ISR hwi in my code does not get triggered. I was wondering if you know why this is. I have attached my code below.

Andrew,

Your SCI configuration looks correct.
I don't know the RTOS part of it.

Thanks and regards,
Vamsi

Can you direct me to the person who knows the RTOS part?

Andrew,

Sorry, I did not check your fifo_init function.
Please enable RXFFIENA bit in SCIFFRX register. This enables RX FIFO interrupt and generates an interrupt when RXFFST is greater than or equal to RXFFIL.

Thanks and regards,
Vamsi
