I’m using Emerald-MM serial PC104 board on the qnx6.2.1.
I configured 6 serial ports(2 in the mother board, 4 in the Emerald board)
devc-ser8250 -b 115200
devc-ser8250 -b 115200 -u3 3e8,7 2e8,7 3a8,10 2a8,10
When I opened and read/write with ser3/ser4, it makes ckeck sum error. But ser5/ser6 was fine. So I tried to change irqs as follows.
devc-ser8250 -b 115200
devc-ser8250 -b 115200 -u3 3e8,10 2e8,10 3a8,7 2a8,7
But ser3/ser4 still makes check sum error.
I think that io addresses (3e8, 2e8) has problem.
Please, comment me how to resolve it?
Thanks
