| 17:33.45 | iluxa-il | I'm going nuts |
| 17:33.45 | iluxa-il | I compile a program with -O1 - it works. I compile it with -Os or -O2 - it breaks. Then I extract list of optimizations enabled by compiler with -Os, and supply them by hand. Everything works again.. |
| 17:33.45 | iluxa-il | What am I missing? |
| 17:48.23 | iluxa-il | and I know for sure the problem is the compiler - switching from 3.4.3 to 4.2.0 (both patched MontaVista releases) causes it |

| 19:56.02 | mne | Is it possible to connect multiple codecs to the AT91 SC/I2S bus and use them all at once ? I guess not, right ? |
| 19:59.39 | likewise | what kind of codecs? |
| 19:59.47 | likewise | i2c is multi slave bus |
| 19:59.58 | likewise | (multi master even) |
| 20:00.55 | mne | no, I2S bus. not I2C |
| 20:01.21 | mne | it's use to transfer PCM sound samples between PCM (audio) codec and CPU |
| 20:04.25 | mne | The thing is that I implemented an ALSA machine driver which uses the SSC I2S bus (data) and the I2C bus (codec control) to talk to a PCM codec. It works and I can play and record sound. However, now I would like to add another codec which also has in- and outcoming PCM samples. Usually that would work well over I2S, but on the I2S bus there's already the first codec. Also both codecs have to work at the same time |
