Problem with usb libraries

[kecC]

Hi.

I'm trying to make a homebrew to connect my PSP to the PC, but I dont know very sure how I have to do it.

There are 4 functions in pspusb.h -> sceUsbStart(); sceUsbStop(); sceUsbActivate(); sceUsbDeactivate();

How I have to use them to connect my PSP to PC? In the homebrew i've done a code that when you push CIRCLE usb have to connect to PC, and when you push TRIANGLE usb disconnect from the PC.

Anyone can help me please?

Thanks for all!

Look at the usb/storage sample

[kecC]

where can i look that?

Thanks

[Arwin]

where can i look that?

Thanks

that would be http://svn.pspdev.org ...

(or http://svn.pspdev.org/listing.php?repna ... rev=0&sc=0 to go to the samples directly)

I've looked the sample and I've done my file, but when i'm going to compile it, it says me:

Code: Select all

main.o: In function 'main':
main.c:(.text+0x1f8): undefined reference to 'sceUsbStart'
main.c:(.text+0x214): undefined reference to 'sceUsbStart'
main.c:(.text+0x224): undefined reference to 'sceUsbstorBootSetCapacity'
main.c:(.text+0x248): undefined reference to 'sceUsbGetState'
main.c:(.text+0x29c): undefined reference to 'sceUsbDeactivate'
main.c:(.text+0x2c0): undefined reference to 'sceUsbGetState'
main.c:(.text+0x2f8): undefined reference to 'sceUsbActivate'
collect2: ld returned 1 exit status
make: *** [usbstorage.elf] Error 1

That seems like if the usb functiones there wouldn't be defined, but the includes to pspusb.h and pspusbstor.h are OK.

Anyone can help me, i'm very lose :S:S.

Thanks!
Bye.[/code]

You have to add the libraries 'pspusb' and 'pspusbstor' to your makefile.

Jim

[kecC]

I've done that, and it continues says me the same. :S

[apache37]

Paste your makefile here

[kecC]

Code: Select all

TARGET = usbstorage
OBJS = main.o

INCDIR = 
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR = -lpspusb -lpspusbstor
LDFLAGS =

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

[Jim]

Should be

Code: Select all

LIBS = -lpspusb -lpspusbstor 
LIBDIR =

Jim

[kecC]

if I put that, it says me:

Code: Select all

/cygdrive/c/PSPDev/bin/../lib/gcc/psp/4.0.0/../../../../psp/bin/ld: cannot find -lpspusb
collect2: ld returned 1 exit status
make: *** [usbstorage.elf] Error 1

Do I need any other library?
I only have pspusb.h and pspsubstor.h in the dir of psp libraries.

Thanks.
Bye.

In the lib folder you should have about 20 files that are named 'libpspXYZ.a' This is where libpspusb.a and libpspusbstor.a live.

In the include folder parallel to that you should have a load of .h files.

I can tell you've not updated your toolchain very recently too.

I only have 6 :S.

Where can i get them?

[Jim]

All the information you seek is on the Wiki.
http://wiki.ps2dev.org/psp:toolchain
You really should read it and try to keep up to date. The PSPSDK changes daily.

I keep getting the following error when I try to compile the usb sample code that comes with the pspsdk:

error: too few arguments to function 'sceUsbDeactivate'

Can anyone spare a few moments to help me, Thanks.

This was fixed in revision 1882:

Update your pspsdk and it should be ok.
