I have two Moxa boards with no problem, possible you need to specify 'baud_base' param. I my case : # 8 ports board: /sbin/modprobe xeno_16550A \ ioaddr=0x1000,0x1008,0x1010,0x1018,0x1020,0x1028,0x1030,0x1038 \ irq=9,9,9,9,9,9,9,9 \ baud_base=921600,921600,921600,921600,921600,921600,921600,921600 # 2 ports board + onboards: /sbin/modprobe xeno_16550A ioaddr=0x3f8,0x2f8,0xdf00,0xdf08 irq=4,3,11,11 baud_base=115200,115200,921600,921600 -- ________________________________________ Maksym Veremeyenko _______________________________________________ Xenomai-core mailing list [email protected] https://mail.gna.org/listinfo/xenomai-core
