Load something in a Module (last post)

Hello all,

When I try to loadexec an Eboot which is in Flash0, sctrlKernelLoadExecVSHMs2() returns 0x80020147, it means : SCE_KERNEL_ERROR_PROHIBIT_LOADEXEC_DEVICE.

Is there a way to start an Eboot in Flash0 ?

Thanks in advance ;)

first of all,
why an eboot.pbp?
a pbp contains metadata like icons and sfo file that are used by the vsh...
wouldn't be a prx(or elf) ok?

Yes it would be oKay ...
But if I use OSLib in a prx, it compile normally but nothing displays on screen :s . That's why I have to use an Eboot, but before I tried to use a prx, unsuccessfully.

The problem is that there is not a proper vsh exec for flash0.
LoadExecVSHMs is for ms as its name indicates, and normal loadexec is for disc0 usage for games.

Maybe some day i will make some more patches so that there is not that device check in loadexec.

OK, so for now, it's impossible to LoadExec an eboot in Flash.
Thanks for your answer !

I'll try to make a prx using OSLib so :s

Has anyone got an idea, why nothing displays on screen with a module, whereas it works perfectly with an Eboot (using OSLib) ?
Are there particular options to change ?

Thanks :)

Its possible, but loading an pbp file, i dont understand.

There an example in the sdk on loading prx files.

I know that, my problem is : with the same code, when I compile it as an Eboot it works, whereas when I compile it as a prx, it doesn't work, nothing is displayed on screen.

My question is : are there any options to change in the code when we compile a prx with OSLib ? (like Heap size, stack size ...)

Thanks ;)

Sorry for double posting, but I finally identified my problem :
A module compiled with libGe, OSLib, Graphics.c... works when I just blit text with printf(), or when I just clear the screen with a particular color ...
but as soon as I load something (a picture, a font ...), the load fail even if the file exists. Impossible to load anything in a module :(

I tried to allocate Heap size (PSP_HEAP_SIZE_KB(4096), I tried a few values), but it doesn't change anything.

Thanks in advance for any help :)
