Yamaha Receiver stuck in Detect/Disable loop
« on: May 11, 2009, 03:14:36 am »
Hi All

I have just got a yamaha rx-v1900 and thought I'd take the time to do a system reinstall with the latest 8.10 alpha release (2.18). Up until now I have been running an early alpha2 release which has been working great.

When I plugged the receiver into the core it detected it, added the rx-v1x00 device and child devices and jumped into the setup wizard to set it up, which was great. I went through and set it up and all was good. Then about 2 minutes after completing, I noticed the serial detection scripts running again and it jumped back into the setup wizard. It then proceeded to do this continually. Fortunately it wasn't adding a new device each time.

I watched the yamaha device in web admin at various stages through the detect process and noticed that when the detection script ran, it was enabling the device and assigning the serial port correctly (/dev/ttyS0), but as soon as the setup wizard completed it cleared the serial port setting and the device was set to disabled. Then the serial port detection would find the active serial port and do the detection and setup all over again because the serial port wasn't assigned to a device. I also noticed that the correct configuration value wasn't being set, so I modified it to match my device. (R0240 instead of R0177).

I tried manually assigning the serial port and enabling the device before the next detection and this seemed to work. The detection stopped and the device was working. But as soon as I turned the receiver off (manually with the remote) and back on, the detection loop started again.

I assume I don't have to leave the receiver turned on 24/7 just because the core is. And I can understand the core enabling and disabling the device when I turn it on and off, but I thought it would remember my serial port assignment and not go into the setup wizard for every detection. And then not get stuck in a loop of redetecting the device.

Does anyone have any suggestions as to what might be going wrong?

I don't know if this will help but when I was trying to set-up my LCD Sarah, (House/Media Wizard), would continuously cycle.

It wasn't until I went into webadmin and setup extra inputs & ruby codes and then completed the wizard with the correct MD com port and input that everything was happy.

So maybe something is out of whack between the r0177 and r0240 codes.
