Hi
My customer has packet loss problem on TMS320F28069UPZT SCIB. Sending and receiving with FIFO interruption.
1. Set baud rate to 115200bps. Which drive from 90M main clock by 90000000 /(8*(97+1)) =114796bps. Because it has 0.35% deviation with 115200, We are not sure whether it cause the problem ?
2. RX ERROR,SCI FRAMING-ERROR;
3. Sometimes, the sending data is wrong when use FIFO interruption, the main error is the front 4 bytes is error or some bytes' stop bit lost.
Daniel,
1.What is the customer using for a clock source?
2.Have you been able to capture the waveform on SCIB's RX pin when the error occurs?
3.Does SCIB only have this issue when using the FIFO's with Interrupts?
Regards,
Cody
