OFFICIAL: IHP100 Series Rockbox Progress (NOT A DISCUSSION THREAD!!!)

I'd say the MP3 playback. We have a long way to go before it works like we want to, mainly because we are building the ground for several codecs at once.

[TCK]

Just noticed that on the list of codecs .sid is considered. Wonderful! I wondered in the past if it was possible for Rockbox to play game music emulation codecs, but I didn't think it would actually be feasibly possible.

Maybe it's too early to tell but would a .spc player be possible, or would there be hardware/licensing issues? And I suppose it wouldn't hurt to ask about some of the other game codecs out there (nsf, gbs, gym, psf, gsf, usf - on the assumption that it'd be harder to implement newer codecs due to hardware demands)? Things like this would save me quite a lot of MBs :E

It's actually EEPROM, Electrically Erasable Read Only Memory. It's a small, 128 byte memory used to stores settings and stuff.

Latests Rockbox progress:

Sound 10% (very basic output working (sin-wave)

Plus some more progress in low level driver:

I2C driver 50% Writing to I2C done
I2S driver 10% Basic I2S output, but not interrupt-based yet
SPI driver 0%
Remote LCD driver (SPI) 0%
Audio ADC/DAC driver 10% UDA1380 Initialization and basic control done (volume control, muting etc)

EDIT: The Coldfire CPU is still running at 11mHz... (i mistaken it wasn't 19MHz)

Here is the Preglow answer to my question about on IRC:
Quote:
preglow Tang: clocking the cpu correctly takes alot of time, i'm pretty certain the wiki will be updated once it's done

[PorkRind]

After a couple of languid days on the wiki, some updates:

Sound 40% ( plays samples with original quality)
I2S driver 50% I2S output works, both DMA and interrupts work
Audio ADC/DAC driver 40% UDA1380 test plays raw WAV files

Complete project status found here.

[Tang]

For the Colfire frequency I quote this IRC extract:

Tang Finally the CPU still run at 11MHz for now no?
preglow in cvs, yes, but linus has got it running full speed
ripnetuk did Linus ever work out what was causing the ATA to fail at high speed?
Tang Ah very interesting
Tang
LinusN yes
Tang Bravo Linus
Tang
ripnetuk what was it?
LinusN well, it looks like the cpu gets overheated at 140MHz when the hard drive is spinning a lot
ripnetuk (all this techy stuff is possibly more satisfying that actually having rockbox on my iRiver
ripnetuk so no major design fault on the iRiver then... thats good
Tang So i imagine even with iRiver fw the CPU run underclocked?
preglow ripnetuk: you wouldn't call overheating coldfire a major design flaw?
Tang Seems to be
preglow not much to be done about it, granted
LinusN Tang: from what i have heard, it is max 96MHz with the iriver fw

FYI, the split editor doesn't work at all. It compiles and can run, but it can't edit any mp3 files on the iriver, since it depends on sound playback and live sound peak information.

3/02/05 version of the Gameboy emulator runs at near fullspeed, in native 2 bit grayscale.

mp3 decoding is said to be near 100% real time according to greatest "chamois" (a french guy not registered here for now)

[Jonny]

Mp3 decoding at 104% realtime and FLAC decoding at 170%. Both at 120MHz.

[Lewis]

but at 120MHz the unit gets quite hot. iRiver only run the unit at 96MHz (apparently)

[Marder]

Mp3 decoding at almost 200% realtime when NOT writing the resulting .wav file to disk (which is currently done to be able to check the correctness of the decompressed audio).

Values significantly higher than 100% realtime for decoding are required to have some reserve and for the extra load of other activities like reading from disk, synchronizing audio output and other Rockbox housekeeping.

To be fair, it's not the actual disk writing that takes so much time, but the dithering of the output samples. The 200% comes from removing both the dithering and the disk writing.

Not really a progress state but a very good news for Rockbox future, found on HA:
http://www.hydrogenaudio.org/forums/...c=32236&st=25#

The UPS man brought my new H120 today, and I am excited about working with the RockBox team on getting WavPack support in there, and I see no reason that Neuros support would be difficult either. And WavPack's low-complexity encoding will make it ideal for portable recording also.

Just keep in mind that the author of this post, named Bryan is...wavpack devloper...

Wave Playback is now true!

Yes there is, not in a very usable manner but still...
If you have a wave file named "sample.wav" into your root folder you can playback part of it in the Debug Section. Sounds like charm!

Indeed XavierGr
in fact it isn't as new since there was WAVE support from a while but it needed a special HEX file to lauch the SAMPLE.WAV. But this spécial audio test firmware was far from practical (only support USB handling to revert to normal HEX file)
Now it's a fully usable Rbx firmware that allow to launch the SAMPLE.WAV file from the debug.
Which is very more practical indeed!

[XavierGr]

Rockboy can finally plaback sound!!!

All Gameboy roms can playback in-game sounds, though the sound itself is still "very" choppy due to lack of optimization in code.

Many thanks to HCl and XShock for their exquisite work!

For those that have flashed here is a "Grayscale with Sound" Rockboy build:
ftp://titania.student.utwente.nl/grayrockbox.zip

(Simply replace the files into the root folder)
