    Working on Learning C++

    Are you sure it's not gdbclient that's integrated in gdb ? on my debian gdb7.1 and gdbserver are two separate packages, and angstrom sure have a gdbserver7.2 package... Oh, and I just remembered you have to use a cross-debugger version of gdb on the client side two (probably something like...

    is gdbserver included too ? could be useful for those of us who'd rather use a graphical frontend to gdb on pandora...

    More floating point performance using hard floats

    Just to be complete, the benchmarks I'm refering to were made in assembly (no need comparing output of compilers) doing simple FIR filters -like calculations (which should fit well for a vectorial FP instruction set like NEON). BTW I tought the thing taking the more space in silicon was the...

    More floating point performance using hard floats

    I think what Letalis refers to is the fact VFP and NEON on ARM cortex A8 are known to achieve 10% perfs (in floating point benchmarks) of current generation Atoms, who already suck big time as they are the equals of 2005 era Celerons. So compared with the modern x86 processor you probably have...

    Working on Learning C++

    My two cents : - debuggers are nice for two things : see your code run step by step when using a complicated algorithm (but you'll need this less and less over time) AND stopping on a particular occurence (class member modified, assert, etc) to examine stack, memory... especially in C++ where...

    Pandora terminal game in a pnd

    I ported weechat, a terminal chat client, recently, and had no specific problem with the terminal. I used terminal --full-screen --command="./weechat" which does the same thing as you, although with a different syntax. Had to force full-screen myself so I guess the terminal you see is...

    Need help building/running kernel/firmware

    Yup, that was it. Thanks. Used 2009-q1-203 and it's now going past the "starting kernel" stage (only to fail a little later of course). Maybe you read about this problem with 2007-q3 on the beagleboard wiki page which is linked in the pandora wiki, and which I should have read myself <_<...

    Need help building/running kernel/firmware

    on the firmware issue (git.openpandora.org vs github/openpandora + handhelds.org down), advice anyone ?

    Need help building/running kernel/firmware

    I saw this console argument thing some time ago and tried the new argument too. Anyway, I just re-did the test, both with tty02 and without the console=... altogether => same result Here is exactly what I see when the boot hangs : Loading file "boot.txt" from mmc1 device 0:1 (xxa1) 168...

    Need help building/running kernel/firmware

    ok, thanks. my SDcard is ext2. I use the same boot.txt as for standard rootfs/kernel, as I'm still not sure what all the args mean (lot of things to learn) : setenv bootargs debug root=/dev/mmcblk0p1 rw rootdelay=2 console=ttyS0,115200n8 vram=6272K omapfb.vram=0:3000K ext2load mmc 0...

    Need help building/running kernel/firmware

    thanks for your answer, I checked and only the OMAP_HS was activated. I switched to MMC_OMAP and activated a few debug option for MMC, but nothing changed. nice to know it's worth the pain :) guess I'm just unlucky or missing something obvious... did you more or less follow the...

    Need help building/running kernel/firmware

    Hello everyone, so since I'm mostly a noob in the kernel/firmware building thing, I've decided to educate myself. I followed a few wikis, and managed to cross-compile (with CodeSourcery 2007q3) kernel 2.6.27-omap1. Installed it in a rootfs on SD Card (with make modules_install...
