Hi guys, I am doing some game programming on the PSP, and I have run into some problems. I am using GDB to debug the program over PSPLink. What I don't understand, however, is the stuff that GDB throws me: ms0:/psp/game/azalende/> Exception - Bus error (data) Thread ID - 0x0...

One I'll mention here is avoid flushing the caches. You'll see code from some folks that flush the dcache every single rendered frame. That DESTROYS your speed. Rather, put all the graphics stuff you're using into uncached space (addr | 0x40000000). This goes for framebuffers too, both onscreen or ...

but since psplink requires a 1.50 firmware

you could use psplinkusb which supports newer kernel stuff


I know that doesnt solve the debugging problem, but you might want to post all of the steps you are going through to start debugging as well.

One thing I had to do in order for it to work was turn off compiler optimizations, so -O0, but I dont know if that will solve your problem as well

Also make sure you have gdbdebug option turned on in usbhostfs_pc, I dont know if you enabled that or not

ah jsharrad, you rule. That seems to have fixed the problem, thank you so much :)

I am on ubuntu 8.04 Hardy Heron. Whenever I reset psplink by typing "reset" into pspsh, I have to completely restart usbhostfs_pc for it to detect the psp again, does anyone know how to fix this?

maybe signal is too weak or psplink don't support some sorf of securities of ur network.. anyway i will be thanfull if u can pack ur psplink directory with settings ini and upload to some upload site, coz' i can't configure .ini properly or i have bad compilied psplink, i dont know ^^ That reminds ...

I am having some trouble with psp-gdb. I am trying to debug a simple hello world app just to get things setup. I cant seem to get this to compile with debug symbols though. Whenever I start debugging and type "info locals" while I am in main, it tells me "No locals." Am I doing s...

yes, the connection works fine in the browser.

I am trying to get psplink to work, but whenever I try to start the wifi shell, it never gets past "connection state 2 of 4." When it prints this message, the wifi light comes on solid for a second, then never blinks again. I have tried deleting the wifi profile and remaking it. Does anyo...

sceGuSwapBuffers() returns the pointer to the new draw buffer

Nobody knows what im doing wrong?

I still dont know what im doing wrong. It seems like my model should show up just as it did before, but adding these things seem to stop it from showing up at all... I added hte weights to the vertex structure: typedef struct pspVertex { float weights[8]; float u,v; unsigned...

Thanks for the replys :) After reading what you said, i went back and changed it so that the first weight on each vertex is 1.0f. With the first bone matrix being an identity matrix, shouldn't my geometry show up unchanged? @Raphael Yeah, i thought so, but i was just throwing stuff in there to try a...

Im trying to learn about skinning, so i am modifying a smiple program that i have that just draws colored triangles. I've added all the parts that i thought i needed to get it to render, but when i compile with all this stuff, i get a black screen. Here is the stuff ive added: i changed my vertex to...

seventoes wrote:frame and length are declared as members of Animation though, and int's can be typecasted to floats just fine, right?

yes, but you need to actually typecast it:

n = (float)frame/length;

the way you have it now, n will always be 0 unless frame >= length

If you actually look at graphics.c it shows you how to use libpng

also, this should help you out

After looking at milkshape, ive discovered that instead of that, the meshes and triangles formed from the vertices are seperate from the bones entirely, only the vertices are connected to the bones. This makes sense, since if have a mesh with two bones and you move one, you want to triangles betwee...

I guess ill start with what im trying to do. What i want to do is write an exporter for milkshape (a 3d modeling program) to write a custom model format. Ive looked into it a bit, and have come across something that im not quite sure how to handle. I always assumed that for bones and animation, ther...

if you turn on swizzling, you need to actually change your texture data, so it knows how to read it.

if you look around the forums, there are plenty of examples on how to swizzle your textures, and i think there are some examples on this site's wiki.

i realize that, but the problem that i originally asked was because i mistyped and forgot to put an m in my code. I thought it might be better (especially for me) to ask about why i needed the m in sceGu m DrawArray, and what the difference was withoutout it, rather than to have a huge question aski...

i dont know how to delete this post, but my new question in the first post stands.

The problem was fixed ^^ but i dont know how to delete posts.

I've edited the post because the question was answered, i needed to use sceGumDrawArray instead of sceGuDrawArray, but can anyone tell me why? what is the difference between the two?

Bytrix I tried to setup my Visual c++ like you said, but when i try to build the project it says device not ready? 1>------ Build started: Project: TestProj, Configuration: Debug Win32 ------ 1>Performing Makefile project actions 1>The device is not ready. 1>Project : error PRJ0002 : Error result 1 ...

nevermind, i figured it out. i was only putting in half the amount of samples (was counting each left and right byte as its own sample). stupid mistake.

thanks for trying to look though, i really do appreciate it

Im trying to get mp3 playback to work with libmad, but i cant for some reason. i can get the mp3 to play, and you can recognize it, but it just sounds funny. it sounds like parts of it are getting skipped, i dont get it. http://rafb.net/paste/results/3ubQen72.html i put my code up there so it would ...

turns out that memset was all it needed.. any idea why?
