RISC OS?


Hello all,

Not posting much these days I'm afraid... Sorry about that .

@Raik : I'm still very much interested in RiscOS on the Pyra, so thanks a lot for your time and effort, really appreciated :)

My Pyra is unfortunately collecting dust, so please let me know if I can help you out in any way with tests and stuff and I'll do my best.

Cheers,

Magic Sam

Thanks for your offer. I will come back to it.
At this time it is a bit fiddly to use RISC OS. It works only on "self powered devices". There is no power output on hdmi and usb.
The GPIO-Expander-Chip that gives the power are not work correct in RISC OS. Many usb and hdmi devices need the power.
Second problem, autostart is not working well. the bootprocess ends im supervisor mode. U need a serial connection and a terminal to start te grafical environment.
The (unpowered) pyra keyboard driver is the problem here. It has to be kill via terminal and than the you have to kick the autostart manually.
I will refurbish riscos.openpandore.org and add an Pyra-part. I hope an usable Image comming soon.
 
Refurbish is not the right word ;)

Any Benchmarks (reference OMAP4 Panda) with any improvements and without serial Debug ...

Processor - Looped instructions (cache)________202%
Memory - Multiple register transfer____________294%
Rectangle Copy - Graphics acceleration test____67%
Icon Plotting - 16 colour sprite with mask_______416%
Draw Path - Stroke narrow line_______________181%
Draw Fill - Plot filled shape__________________397%

Step by step but very slowly...
