Hi all, Does anyone have any knowledge of an issue we are seeing with RTEMS 5 SMP on GR712RC related to interrupt-driven APBUART console and termios during full-duplex (simultaneous read and write) data flow?
The termios tty transmit gets stuck in its "busy" state when one application task is reading and a different task is writing the serial port at the same time. I am wondering if it may be related t the GR712RC UARTs sharing of a single interrupt for both RX and TX in a SMP architecture? We have a very simple test application that reproduces the problem 100% of the time on the 4th call to "write()". Thanks for any insight! Don
