Hi,
I have trouble receive bytes of data using UART RS232 port on uClinux running NIOS2 /f. A loopback application was implemented to send 128 bytes hex data from ttyA0 (RS232 port) and receive on ttyA5 (RS232 port). This is a DE2-115 development kit. The IRQ for both port is 1 and 2. I have a JTAG for nios2-terminal, but it's irq is 3. I have disabled the flow control (ctsrts, xon/xoff,etc), but each loopback test I do, I always missing 10 to 11 bytes. However, if I send less than 10 bytes of data, I have higher chance of success getting the same bytes across. If anyone know of this problem and have a solution to it, please kindly let me know what I am missing?
Thanks,
Yeung
