Update: I installed a Moxa 4 port PCI serial card, which has a shared interrupt for all 4 ports. I did this: modprobe xeno_16550A io=0xd040,0xd048,0xd050,0xd058 irq=17,17,17,17 baud_base=921600,921600,921600,921600
This worked fine, I was able to communicate bidirectionally on all four ports in sequence, indicating that my kernel and xeno_16550A module are compiled correctly for shared interrupts. I'll try simultaneous use of these ports tomorrow. The previous problem must have been the actual serial ports I was using, which are the ones provided by the motherboard. thanks, -C Smith _______________________________________________ Xenomai mailing list Xenomai@xenomai.org https://xenomai.org/mailman/listinfo/xenomai
