Re: Does RPi support multi-master I2C?

Multi-master is required if you want a provably robust solution to the problem. If random, transient failures are not a problem in the system (and maybe they are not), then that's another thing. I suspect that you could make the new bus-master recognize the situation and more-or-less deal with colli...

Re: Does RPi support multi-master I2C?

I never heard one way or the other, so I gave up and went with USB between the Pi and my board. I would still be interested in knowing if the Pi could support I2C master with arbitration though.

Re: Does RPi support multi-master I2C?

OK, then at least the hardware supports it. I don't need the ability to have the RPi act as a slave, I just need it to gracefully lose arbitration (if required) during a message send of its own. Forgive my ignorance of Linux/RPi driver issues, but does the RPi I2C driver exist in source somewhere? C...

Does RPi support multi-master I2C?

I want to build an external board that contains a processor and a bunch of I2C peripherals. The external board would be designed to act in a standalone mode, or as a smart peripheral if connected to a Pi. The processor on the external board would support multi-master and slave operation, so that it ...

Re: You wanted MPEG-2? You've got it!

I use nano, so no problem there. My serial should be OK. I checked it a couple of times before sending it in. I'll try a fresh image next. OK, fresh install, update, upgrade, EVERYTHING using a brand new SD card. Exactly the same: no MPEG decoding. All I get is "have a nice day". Which I am not hav...

Re: You wanted MPEG-2? You've got it!

I just tried with 128M: it is essentially identical to the case where I had 192M split with the key present except that the message [mpeg @0x--------] shows a different address. Omxplayer just hangs, and I have to ^C to exit it. I don't suppose you have a spare SD card lying around that you could t...

Re: You wanted MPEG-2? You've got it!

I get three more lines with the key in the config file, but no video, no sound. I let the version with the key present sit all night and omxplayer never exited or did anything other than hang after printing that text. What memory split are you using? Can you try with 128M? I am using 192/64 split. ...

Re: You wanted MPEG-2? You've got it!

So if you remove the licence key from config.txt does it behaves differently? I'd expect it to exit immediately with "have a nice day". No key in config.txt: > omxplayer TITLE01-ANGLE1.VOB [mpeg @ 0x11b57b0] max_analyze_duration 5000000 reached at 5000000 Truncating packet of size 2025 to 394 file ...

Then, I get those errors and the wireless quits. If I remove the wireless dongle, the keyboard starts working (although I do get sticky keys!). If ...

OK, as it turns out, the password needs to be the pass phrase, not the hex version of the same. With a pass-phrase in place, I have wireless network access!
