GPS RB800 Problem

w0lt · May 24, 2010, 2:24pm

When using serial0 for GPS input, the RB800 will not reboot..it just stalls. Removing the GPS connector from the external serial port solves the problem.

This does not seem to be a problem when serial1 is used for GPS, and serial0 is used normally for the console. If I disconnect the GPS unit (Garmin GPS-V) from the RB800, recycle the power, let the RB800 boot up, then reconnect the GPS, the RB800 will work correctly processing GPS input till I reboot again.

Is there possibly something that is not getting reset in the serial port during reboot if a GPS is connected?

Your GPS NMEA string is tripping up the bootloader.
The following is well documented throughout the forums and should resolve your issue.

/system routerboard settings set silent-boot=yes enter-setup-on=delete-key

Thanks for the tip. I haven’t experienced this with other routerboards as it works just fine on the RB411AR and 433AH. It seems that I only needed to set the “enter-setup-on=delete key”, the silent boot seems to be not necessary.
