RFXCom Red led solid lit after reboot Synology, needs unplug

[pwhooftman]

Lately, after rebooting my Synology DS412+ the red led on the RFXTRX433 stays lit solid. I have to disconnect & reconnect the RFXCom repeatedly until communication with the RFXCom is restored.

There seems nothing wrong with the RFXCom when connected to a PC & RFXManager. Any clues how to prevent the RFXCom from being hung up after a reboot?

(firmware v 69)

Edit: The Synology log reads:

Code: Select all

It seems an enter bootloader command string is transmitted by the Synology.
After start up send this string to exit the bootloader: 0x02 0x02 0x00 0x00 0x00 0x03

Maybe not the place to ask it as it is not related to the problem, but i wil do it anyway. How are you using RFXcom i.c.w Synology and with what software/app?

Thanks.

Alas, none of these commands make the RFXCom strt responding again, the red led stays solid lit.

echo 0x02 0x02 0x00 0x00 0x00 0x03 > /dev/usb/ttyUSB0
echo '0x02 0x02 0x00 0x00 0x00 0x03' > /dev/usb/ttyUSB0
echo "0x02 0x02 0x00 0x00 0x00 0x03" > /dev/usb/ttyUSB0

I'm using Domoticz (you'll have to compile from sources yourself). Also usbserial.ko and ftdi_serial.ko should be loaded.

Sorry, the string must be: 0x55 0x55 0x00 0x00 0x00 0x04

Too bad, this string doesn't seem to get the RFXCom out of the bootloader.

Its odd, the RFXCom used to start up succesfully in the past after a Synology reboot.

Your kernel/user-space is likely probing/initing the device, which is what is causing this. You should check which modules are attempted to load and if you maybe have a serial console defined in /etc/inittab or /etc/init.d/* (and other locations depending on your distro)

Hi Jeroen, thanks, yes, that seems to be the case, the log show more references to different USB devices being probed and not recognized properly during boot. Those devices (UPS, DVB-C receiver, DVB-T receiver) don't seem to care though, as they function properly afterwards. I'll examine inittab and init.d tonight (not sure what to look for btw, is there a way to exclude a certain USB device from being probed during boot (is that even the way to solve things)?)
