I would like to work on a CFW not based on Nintendo's code, but the first part of that (to me anyway) is to get code execution on ARM11 from ARM9 FIRM_LAUNCH. Sure I could make one in ARM9, but that would be limited.
Bonus: Could I can get all (4 3ds/6 new 3DS) cores at once, not needed at all. |

Posted by gudenau I can't help with that, just wanted to say thumbs up for the success of this project. Sounds very interesting! |

Posted by gudenau You could contact 173210 and others on github, from those repos of CFWs under active development. And i would say good for this too. |

Posted by gudenau You're meant to remap it. |

How would I dump the memory map? |

There won't be one after FIRM launch, the ARM11 will be operating with physical addressing.
You will have to enable the MMU yourself. |

Posted by Dazzozo This sounds like fun. To bad we can't dump the bootrom; correct? |

You don't even need the bootrom for any of this. |

Posted by Dazzozo I guess your correct... It is FIRM stuff. -.- Over over complicating things as per usual. |

Posted by gudenau As for your overall aim here, I suggest you first spend some time understanding how NATIVE_FIRM operates, before trying to replace it. Specifically, how it brings up the ARM cores and to an extent, how it prepares them for shutdown (and generally how FIRM launch works). Otherwise, you're trying to run before you can walk. |

Posted by Dazzozo That was part of the plan, I was just hoping that someone had the ARM stuff figured out so I could get a simple POC setup. |
