TPU question
2004-05-24 by avoros
Hello All! I hope Charles is out there listening... I have a problem on a (previously) stable platform with the TPU QOM function. Here is some details: I had 4 pairs (TX/RX) of TPU UART functions running at 19200 Baud, 2 pairs running at 9600 Baud, 2 QOM channels (for output) and 2 FQD channels for input. All was OK until I had to increase one of the 19200 UART channels to 57600 Baud. What happened is that one of the QOM channels fails after a variable time (20 mnutes to 2 hours obsereved). It does not change the output to the last match state (btw: it is used only as a one shot of approximately 250us). Priority levels are high for receivers, mid level for transmitters and QOM, and low for outputs. I don't see anything wrong code at all (like I said it has been working for years) the QOM is ONLY triggered as a one shot. Period. The UART docs mention a maximum baud rate (aggregate) when both TX and RX's running of 143KBaud. My total with the 57600 is 134KBaud. All UARTS are working OK. Anyone any ideas?? Attila
