    Can We Put 'pandora' In This Forum Name

    When selecting 'View New Posts', it only shows the forum name, not the category name. Hence, posts in here show as being in 'General Talk'. Can we add 'Pandora' in the forum name similar to how it is done in 'GP2X' so 'View New Posts' is much clearer?

    GP2X Building Open2x Toolchain To Run On Gp2x

    I can build the Open2X toolchain for Cygwin. Can I build it for GP2X? Example: BUILD=i686-host_pc-cygwin HOST=arm-open2x-linux TARGET=arm-open2x-linux I tried setting HOST to arm-open2x-linux before running open2x-gp2x-apps.sh, but that did nothing.

    How To Reset Root Password

    For some strange reason, I changed the root password on my GP2X. I know what it is, but I now want to reset it back to what it was before, i.e. blank, empty, nothing. How do I do that?

    Gp2x Squeals

    I had left my GP2X off, but still plugged in to the power adaptor (powered on) and USB connected to the PC (also off). It had been like this from midnight through till 6:30pm, so about 18 and a half hours. After this time, the GP2X was squealing softly, like a mosquito, even though it was...

    GP2X Open2x Toolchain On Windows

    Has anyone successfully downloaded the open2x toolchain source code to Windows? It fails because there are two files in toolchain\linux-headers-2.6.12.0\include\linux\netfilter_ipv4 that only differ in case (ipt_TCPMSS.h and ipt_tcpmss.h). This may be legal and possible on a case-sensitive...

    GP2X Anyone Got A Backtrace Working In Code?

    I'm trying to output the callstack, or backtrace, in my programs if an assert fails. I'm using the following code which seems to be the proper way to call the backtrace functions. void *stack[32]; unsigned long stackSize = backtrace(stack, 32); char **strings = backtrace_symbols(stack...

    The Coolest Dev Setup

    I just got my new toy, a Sony Vaio VGN-UX17GP Ultra Mobile PC. Just had to show it connected to the GP2X. The quick run-down on the specs: - 1.2GHz Intel Core Solo - 512MB RAM - 30GB HDD - 1024x600 LCD touch screen - Biometric fingerprint reader - 2 cameras - Wifi, Bluetooth - 3 hour run...

    Microsoft Mechcommander 2 Shared Source Release

    Microsoft MechCommander 2 Shared Source Release Before anyone asks about a port, the answer is not very likely. A snowball would likely have more chance in hell. :)

    GP2X How To Write An Exception Handler

    There is usually an exception handler that can be written to respond to NULL pointer dereferences, divide by zero, etc. Does anyone know how this would be done on the GP2X?

    GP2X Ac97 Codec Registers

    I'm trying to work out what this code in rlyeh's Minimal SDK does. gp2x_memregs[0x0F16>>1] = 0x830a; usleep(100000); gp2x_memregs[0x0F58>>1] = 0x100c; usleep(100000); I've figured out that they are some AC97 codec registers, but the databook does not go into any further detail...

    GP2X Larger Frame Buffer

    One common method of scrolling in days gone by was to have a frame buffer that larger than the display area. Various registers were set to tell the display which part of the frame buffer to display. In effect, you could get a limited amount of scrolling without redrawing the frame buffer at...

    GP2X Sound Mixing Routines

    Does anyone have any sound mixing routines they would like to share? I've got a sound mixing routine, but it's nothing special. Does the job, but that's about it. Note that I know zero ARM assembler, so I would not have the faintest clue about how to rewrite my current C implementation in...

    GP2X Optimization Settings

    I'm using Rlyeh's Minimal SDK and I have the blitter working very well (based on paeryn and gfoot's work), but only if I do not specify any optimization level. Even if I use -O1, the app locks up on the first blit. I added a heap of trace statements through the blitter (logging out the file...

    Not So Portable Handheld

    Having just received the serial cable from Nigel, my GP2X is now even less portable than it was. Currently I have a power cable going to the power adaptor on the floor, the USB cable going to a USB port on the front of my PC and now the serial cable going to a serial port on the back of my PC...

    Tinygl

    Here is the gears example from TinyGL running on the GP2X. It is running at about 10fps, but it is still using floating point numbers all through the code. It has not been converted to fixed point yet. It was once again a "port until it runs" effort. This one I think has more potential...

    Vincent Opengl-es

    I have tried porting Vincent OpenGL-ES to the GP2X, and have had some success. The Dodge Viper from the example code supplied with Vincent. It runs quite slowly (I'd guess at about 3-4fps), the texturing is not right, and the original code is the most horrid abuse of C++ I have ever seen. If...

    The Strangest Thing

    I get home from work today, I look at the GP2X that has been sitting at home all day, and the screen is full of the coloured vertical lines, but they are flickering at about 1/3 normal brightness. The strangest thing is that the unit was switched off. It is connected to an AC adaptor, the...

    Converting A Fat32 Partition On The Sd Card

    The Firmware Upgrade page on the GP2X wiki states that using cfdisk (a Linux utility) to create a FAT32 partition of type 0xB works. The FAT32 Resource Page details that there are two different partition types for FAT32. Type 0xB is a standard FAT32 partition. Type 0xC is a FAT32 partition...
