Re: ThumbDV / ambed / AMBEServer reliability on Raspberry Pi 2 ?

Eric Osterberg

I would second that comment about power supplies. Nearly every problem (rare) I've ever had with my many Pi computers can be boiled down to weak power supply or the USB cable that feeds power... Keep cables in mind. All my problems in the past 24 months have been cable related. Even 12" long cables I have used in the past have become the 'power limiting' defect. These same cables still test and work for many things, just not power. New trusted, well made, large gauge cables have fixed my issues.

The XLX folks do not recommend the Raspberry Pi for ambed.

As far as Raspberry Pi in general, many of these issues are power supply related, both voltage (there is a drop through many leads and current output.   I would review my power supply first.

Hi all,

I'm running twi different setups :
- ambed with two ThumbDVs on a Raspberry Pi 2 (for XLX)
- AMBEserver with one ThumbDV on another Raspberry Pi 2 (for DVSwitch Analog_Bridge)
Both seem to malfunction after a while : scrambled audio, no audio at all, timeout errors in the logs, etc... Rebooting the RPi solves the problem, but the problem may appear again  later.

All the machines (XLX server, Analog_bridge, and the two RPIs) are in the same data center, and on the same VLAN. So, this is not a network latency problem, nor a port opening issue. Also, power supplies are "official" Raspberry Pi ones.

Did someone already encounter such issues with RPi 2 ? As USB problems are frequent topics in the RPi world, I'm thinking about connecting ThumbDVs through powered USB hubs. Any other ideas ?

Thank you in advance. 73 de TK1BI
