Hmm, I get a 72kB .prx.Torch wrote:First of all when making a kernel module always use USE_KERNEL_LIBS=1 and USE_KERNEL_LIBC=1 or you'll end up with bloated code like 100KiB for a kernel module which would normally be 2KiB.
Well I don't have a clue about loading the module otherwise. Any lead?Torch wrote:And you're ideally not supposed to use user functions from kernel mode either. Find a way without the user functions.
It doesn't help, but in fact even specifying "blah" will return 0x80020149.Torch wrote: Regarding your problem:
The cwd may not be set. Give the full path for hello.prx
Neither :/The &options struct may not be set properly. Anyway it's not necessary for simple loading so make it NULL..
It's in a thread already.It may not work from inside module_start and some non-thread contexts. Make sure you are calling it from a thread.
Hmmm, it doesn't show on the forum but did you know that a trailing space in 'USE_KERNEL_LIBC=1 ' can seriously mess you build? Just learnt about it XDBeuc wrote:Code: Select all

} Yes, the code was as-is, since I was aiming at getting something that worked before trying to trim it.Torch wrote:Lot of unnecessary crap in your code. And yes the trailing spaces in the makefile lines screw things up.
