No apps should really be using fixed addresses for normal ram access, they should be accessing either heap address, internal data section addresses or stack addresses all of which can change as long as you use a relocatable executable. ..I have to read into it elf-loading. ...So not all elf-binarys...

Thank tacoSunday for your response As J.F. said, I first should read into ELF-loading a lil bit, then I will probably understand better how I can solve my stuff. What you said about it confirmed what I have guessed about loading. If you hardcode a specific address in a module, say 0x09000000, then c...

Yea, Tyranid you understood. That's exactly what I want :D A memory allocater. There you are in luck, the kernel already hands out allocation blocks. Normally you don't see it but the executable, stack and heap are all allocated out of memory using a simple block allocator. Yes I saw these functions...

Thanks J.F. and Jim
This information is very useful. I now have a more general idea how it could work, I will work on it and I hope I can get back if I have questions later on.

Multi-tasking and memory protection are two completely different things. You mean, like men and women ;) Or like Macs and PSPs (sorry I couldn't stop myself from saying that :|| At the moment I simply cannot think of a way to multitask between apps on the psp without memory-protection (or whatever ...

Hmm ... ok - thanks for the additional information. But without insulting you - this is not really what I wanted to know. Thanks anyway ;) Don't hit me - but I had the idea of a multi-tasking engine that integrates seamless into the system. Thus, I would have needed memory protection.. I could cache...

Thanks for your reply I am not sure you quite understand, by default in user mode you get all the RAM you are allowed to have just there for you to use. Well, that's what I was worried about. So, I interpret what you said as: "My user-mode program can use the memory it wants and the kernel can'...

Hey there Since I got nothing on the on this found here, I'll ask. I am about to think writing a piece of softstuff for the psp. But before I go to the workbench I want to clarify a few things.. I found the int sceKernelSetDdrMemoryProtection function in the sdk and obviously it protects a memory ar...

Hi

I think it would be nice if there were some kind of wizard in which you press the keyboard buttons and then manually map it in the wizard on a specific key. Just an idea. I haven't read all the thread ... but ...ye

gringo

so... I'm replying myself because one minute after my first reply I found the answer in these forums sticky thread ;)

But if you have other sources you may speak ;P

thanks weltall...

...for the valuable hint. That's awesome!
Since you have access to these firmware functions - how good are those functions documentated (and where).

Hi folks I've looked through the Wlan-Scan sample code in the psp-sdk and I found these function calls: int sceNet_lib_5216CBF5(const char *name); I didn't found where this function is implemented - just found the string "5216CBF5" in the pspnet library. Can someone tell me...
