    Waiting in October

    Juliano deserves a free Pyra, I suggest. Nice job with signal integrity testing and the video!

    It's the keyboard layout.

    Strong vote for dedicated ESCape key (vim). But most important: Software support (built-in from the start) to freely assign any key to any function. Would it not be best if the keys could be easily exchanged physically? Then a set of keys for any language could be sold and people would just...

    Some PCBs, holidays, a new case revision and a theme

    Exciting, indeed! One day EvilDragon will have to write a book: HOWTO efficiently produce a quality device from scratch :-)

    Nothing to show, but a lot happened.

    How about moving the two new shoulder buttons to the BOTTOM of the case, a bit to the center so they can be pressed with the middle or ring fingers? I have used this type of modded XBox controller: http://www.evilcontrollers.com/catalog/product/gallery/id/968/image/2978/ The buttons on the...

    Very interesting points, thanks! I will update the OP with "optimizations to try".

    Pandora Best GCC command options for Pandora compilation (Sourcery toolchain)

    Sorry, I forgot to make it clear that I am not compiling on the Pandora itself but cross-compiling on an Intel PC with 64-bit Ubuntu. The Sourcery toolchain is not specifically for the CPU of the Pandora and I think it is a good idea to tell it the exact details of the target platform. As...

    Pandora Best GCC command options for Pandora compilation (Sourcery toolchain)

    Thanks for the input, I will change the OP to show only command options that are in some way specific for the Pandora. "-ftree-vectorize" seems to be an aggressive optimization that is included in "-O3": -ftree-vectorize is going to be turned on under -O3

    Pandora Best GCC command options for Pandora compilation (Sourcery toolchain)

    [Last updated 2012-03-04] This is an effort to establish the optimal GCC command options for cross-compiling for the Pandora on another computer. All contributions are welcome! This should be seen as a sane starting point, but not prevent anyone from experimenting and posting their...

    Compiling SDL_sound

    Thanks a lot! If I find some time I would like to adapt GLtron to support the Pandora analog sticks in a different way (southpaw). And other code to port may well use this library, too.

    Accessing content of rootfs.img? (from Zaxxon-HF6.zip)

    No, not really. I just got carried away with ambition :) As long as the files are provided together with the image, the whole exercise is pointless. But fascinating, nevertheless :rolleyes: It might be useful one day if you make a "nanddump" on your Pandora (maybe as a backup) and later...

    Accessing content of rootfs.img? (from Zaxxon-HF6.zip)

    Successo!! I have finally figured out how to get at the contents of the raw Pandora NAND image! I used a 64bit Ubuntu 11.10 system. I remember installing the following package, but maybe there were more: sudo apt-get install mtd-utils The procedure is as follows: First you...

    Accessing content of rootfs.img? (from Zaxxon-HF6.zip)

    Thanks a lot for the good advice! The best solution is indeed to get the data from here: http://openpandora.org/firmware/ A related question was discussed here: http://www.gp32x.de...e__hl__ubimkvol A link about how to extract files from an UBIFS image...

    Accessing content of rootfs.img? (from Zaxxon-HF6.zip)

    Does anybody know how to access the content of rootfs.img extracted from Zaxxon-HF6.zip? I would like to access the firmware of the Pandora on a Ubuntu Linux machine. Especially the libraries. I don't get further than the error shown below. What filesystem is used in rootfs.img? Or am I...

    After a long day, there'll be another one (2011-12-21)

    Awesome Christmas gift, congratulations! I just have one complaint now about ED: He should change his nickname from EvilDragon to SublimeAngel!
