Stable, Consistent and Self-Documented SDK for the PSVita.

If you don't need a specific psvsdk version, you can easily build and install it. However, new PSVita APIs are discovered/updated everyday. To get a reproducible build, one shall use a versioned docker image : docker run -rm -it psvsdk/psvsdk make

The psvsdk provides a set of tools to compile your C sources into a PSVita compatible binary using the following workflow:

graph LR
main.c & sceCtrl.a & sceNet.a --> psv-gcc --> main.elf --> psv-velf --> main.velf --> psv-self --> main.self --> psv-vpk --> main.vpk
psv-sfo --> param.sfo --> psv-vpk

• Compile main.c into an ARM ELF using psv-gcc which is arm-none-eabi-gcc with extra flags.
• Convert this ARM ELF into a Vita ELF using psv-velf.
• Sign this .velf using psv-self into a signed Elf .self.
• Create an SFO file using psv-sfo to describe your application to the LiveArea (title, version, parental, ...).
• Bundle both .self and .sfo into a .vpk VitaPacKage using psv-vpk.

Example:

psv-gcc  main.c -o a.elf
psv-velf a.elf  a.velf
psv-self a.velf a.self
psv-sfo  TITLE="Hello World" ... > a.sfo
psv-vpk  a.self:EBOOT.bin a.sfo:sce_sys/param.sfo > a.vpk
#curl -T a.vpk ftp://$IP:1337/ux0:/

We can generify them in a Makefile:

%.elf : %.c         ; psv-gcc  $^ -o $@
%.velf: %.elf       ; psv-velf $^ $@
%.self: %.velf      ; psv-self $^ $@
%.sfo : %.ini       ; psv-sfo  $(shell cat $^) > $@
%.vpk : %.sfo %.self; psv-vpk  $(word 1,$^):sce_sys/param.sfo $(word 2,$^):eboot.bin > $@

Note: You'll need the build-essential and gcc-arm packages to build the psvsdk

• Build the toolchain using make. (see Makefile for possible options)
• Install globally (require sudo): sudo make install
• Install locally (only for you): OUT_DIR=$HOME/.local/bin MAN_DIR=/tmp make install
• Build locally a Docker image: docker build -t psvsdk/psvsdk:latest .

Feel free to take a look at the .travis.yml or the Dockerfile to see how the prebuild SDK is made.

• ELF: Executable Locatable File.
• Module : An ELF file that exports/provides 1-N libraries and imports/requires 0-N libraries.
• Library : A set of functions related to a common topic (Ctrl,Io,Thread ...).
• NameID (NID): 32-bit hash generated from a salted {module, library, symbol} name.
• VELF: Generic ARM ELF with Vita-specific sections .sceModuleInfo.rodata and Import/Export definitions.
• SELF: Signed VELF
• FSELF: Signed VELF but with an empty (0000...) signature.
• Stub: Piece of code that feign a function, so the code can compile, but in real life, this function will only be available at runtime.
