Hm. I would measure the unconnected RX pin voltage. It should be pulled high by a resistor as they can't left it floating. If you measure no voltage at that pin it likely means that it is not connected on the board. Another thing to test is playing with the bps-rate. 120000bps seems an odd datarate, but unless it is precisely measured it could be anything else. The receiver on the router might be more picky about matching speed than your computers serial. > Does the serial console work once openwrt is booted? > > > -a > > > > On 30 November 2015 at 14:40, Michael Iline via freebsd-mips > wrote: > > Hello everyone. > > I've been working hard on trying to get FreeBSD on my wr1043nd v2.1 but I'm having a lot of trouble that nobody else seemed to encounter...

Viper-7 from ##electronics at freenode suggested that other methods of flashing the image may be used, since I do have an working OpenWRT installation. He recommended this: https://wiki.openwrt.org/toh/tp-link/tl-wr1043nd#flashingrecovery_using_tftp_only_without_serial_consoleI'd like to hear some thoughts before I go ahead and do this, as because of my serial writing issues bricking the device would be extra painful for me. > > Please let me know of someone can provide some assistance, and be sure to tell me if you need any more info. > > Thanks in advanceMichael > > > > _______________________________________________ > > freebsd-mips@freebsd.org mailing list > > https://lists.freebsd.org/mailman/listinfo/freebsd-mips > > To unsubscribe, send any mail to "freebsd-mips-unsubscribe@freebsd.org" > _______________________________________________ > freebsd-mips@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-mips > To unsubscribe, send any mail to "freebsd-mips-unsubscribe@freebsd.org" -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
