hi there!
first of all: i have searched the forum for this and coudln't find anything that helped me. that doesn't mean that it isn't out there, burried in some thread, though! so, if you have a link to a simmilar topic, please post it.
this has already cost me a day worth of coding and it's making me nuts!
it's very important that i get this done very soon, so: *please*, help me.
i've been updating my volume shadow demo and my texture loading code, that worked with older libnds versions (i can't remember which one it was, as it's been a while and i've updated libnds a few times since), will hang the hw on the following lines (although the *free* version for no$gba 2.6 will not show any error, but won't display textures, just colored and lighted geometry):
dolltex is a global 'int' and pTexData is a local 'uint16' pointer (to 16bit texture data.)
if i insert infinite loops ( while(true){} ) before each line, the first loop will be entered and the hw will not hang (i can tell that by printing something out to the screen.) as i remove the loop before the first line, the hw will hang.
what is going on?
how can this possibly be?
has anyone else seen this behaviour?
any advise / hint / (constructive) criticism is appreciated. :^D
as the project is open source anyways, i can make the current sources availabe, if needed, but i don't think i am doing anything wrong! :^(
EIDT: i also have to note that i've been and still am loading textures in the main function (adding wait for vblank doesn't help here.)

| Code: |
| glGenTextures(1, &dolltex); // will definitely hang the hw
glBindTexture(0, dolltex); // possibly, too, because of the first one glTexImage2D(0, 0, GL_RGB, TEXTURE_SIZE_256 , TEXTURE_SIZE_256, 0, TEXGEN_TEXCOORD | GL_TEXTURE_WRAP_S | GL_TEXTURE_WRAP_T, (uint8 *)pTexData); // well, i really don't know, but chances are, that this screws up, too, due to the others not working |
dolltex is a global 'int' and pTexData is a local 'uint16' pointer (to 16bit texture data.)
