Reboot of 'start.elf'.

[rosery]

Is it / Can it be possible to restart the 'start.elf' (I presume) system to take account of different parameters in the config.txt file. This would be really really helpful. This particularly relevant in relation to the r<->b swapping, and whether ot not to ignore the alpha channel. .. indeed, is 'restarting'the start.elf what is required?

thanks

Look at arch_reset:

Brilliant. Thanks

I think we need to take a look at how the RISC OS buffer features are
exposed. Would you prefer the "different mailbox message" signalling
to config.txt parameters?

Cheers

Yes.. a mailbox method would be easier than config.txt .. It then gives us 'proper' control of the environment, rather than hoping the correct values were poked into the config.txt.file.

However, given that we can (according to the thing above) restart things, maybe that isn't quite such high priority as getting to a hardware cursor etc.. issue 38

Closing as reboot issue is solved, and mailbox channel is discussed in #47
