PSVita Linux build instructions

PSVita_Linux_build_instructions.md

0) Optional: Solder UART0 pins

1. Check here for the pinout. You will also need a 1.8V level shifter.

1) Install an ARMv7 cross-compiler

1. Go to https://toolchains.bootlin.com
2. Select arch: armv7-eabihf
3. Select libc: glibc
4. Download bleeding-edge
5. Uncompress it (for example to /opt)
6. Add the bin/directory of the toolchain to $PATH
   • In my case: export PATH=$PATH:/opt/armv7-eabihf--glibc--bleeding-edge-2023.08-1/bin

2) Build Buildroot

1. git clone git://git.buildroot.net/buildroot && cd buildroot
2. Download and copy this Buildroot .config to .config
3. If using a toolchain path different than /opt/armv7-eabihf--glibc--bleeding-edge-2023.08-1:
   • make menuconfig
   • Navigate to Toolchain --->
   • Properly set the Toolchain path, save and exit
4. Create a rootfs-overlay directory. Everything you put inside will be part of the rootfs.
5. make -j
6. This will generate output/images/rootfs.cpio.xz

3) Build Linux

1. git clone https://github.com/xerpi/linux_vita.git
2. cd linux_vita && cp ../buildroot/output/images/rootfs.cpio.xz ./
3. make ARCH=arm vita_defconfig
4. make ARCH=arm CROSS_COMPILE=arm-linux- -j
5. make ARCH=arm CROSS_COMPILE=arm-linux- vita1000.dtb vita2000.dtb pstv.dtb
6. This will generate arch/arm/boot/zImage and arch/arm/boot/dts/{vita1000.dtb,vita2000.dtb,pstv.dtb}

4) Install vitasdk

5) Build vita-baremetal-loader

1. git clone https://github.com/xerpi/vita-baremetal-loader.git
2. cd vita-baremetal-loader && make
3. This will generate baremetal-loader.skprx

6) Install libbaremetal

1. git clone https://github.com/xerpi/vita-libbaremetal.git
2. cd vita-libbaremetal/libbaremetal && make install

7) Build vita-baremetal-linux-loader

1. git clone https://github.com/xerpi/vita-baremetal-linux-loader.git
2. cd vita-baremetal-linux-loader && make
3. This will generate vita-baremetal-linux-loader.bin

8) Build and install the Plugin Loader VPK or vitacompanion

Two main methods: (a) a VPK that loads a kernel plugin, or (b) my fork of vitacompanion that has an custom command to load skprxes.

a. Plugin Loader VPK method:

1. git clone https://bitbucket.org/xerpi/vita_plugin_loader.git
2. cd vita_plugin_loader && mkdir build && cd build && cmake .. && make
3. Install plugin_loader.vpk

b. vitacompanion method:

1. Build and install vitacompanion
2. To launch an skprx run:
   echo "load_skprx ux0:/myplugin.skprx" | nc $PSVITAIP 1338

9) Boot Linux

1. Copy baremetal-loader.skprx to ux0:data/tai/kplugin.skprx
   • Configurable in vita_plugin_loader/main.c:13
2. Copy vita-baremetal-linux-loader.bin to ux0:/baremetal/payload.bin
   • Configurable in vita-baremetal-loader/config.h
3. Copy linux_vita/arch/arm/boot/zImage to ux0:/linux/zImage (uma0 if using sd2vita)
4. Copy linux_vita/arch/arm/boot/dts/{vita1000.dtb,vita2000.dtb,pstv.dtb} to ux0:/linux/ (uma0 if using sd2vita)
5. Launch the Plugin Loader VPK

More information

• Check https://github.com/xerpi/vita-linux-loader/blob/master/README.md
• Linux Driver status can be found here: https://wiki.henkaku.xyz/vita/Linux_Driver_Status

Deprecated steps

4) Build vita-linux-loader (DEPRECATED: use vita-baremetal-linux-loader instead)

1. Install vitasdk
2. git clone git@github.com:xerpi/vita-linux-loader.git
3. cd vita-linux-loader && make
4. This will generate linuxloader.skprx

@DvaMishkiLapa do u have the rootfs compressed image? and can u send it? i would like to modify some stuff to remove the login screen (cuz i also wanna run it hehe :3)

or u could just extract the rootfs that buildroot gave out, like THE compressed rootfs, and then after extracting it, type:

cat etc/inittab

that file has the initial stuff, yk, the stuff that prepares the env to start, find the getty line (like console::respawn:/sbin/getty -L console 0 vt100 # GENERIC_SERIAL), then replace it with console::respawn:/bin/sh -l

and after that, compress it back and then continue with compiling linux to have the standard zImage, that's how u remove the login screen

or simply, go and recompile buildroot with getty disabled AND, AND AND AND (yes, required and should NOT be missed) set the init as /bin/sh -l

yw :3

Hello

Help me for plugin_loader.vpk released (compile)

Can anyone share the link?

Mediafire maybe

Thank you

@Dny19 i advise u try out this repo https://www.psx-place.com/resources/bootmenu.1024/

the vpk is kinda broken rn, and this solves it
