Computer Requirements

USB-A cables are recommended to use, USB-C to may have issues with palera1n and getting into DFU mode.

Due to USB-C cables having different accessory IDs, your device may not be able to be recognized when using USB-C due to not being able to assert to its USB voltage pin.

Linux or macOS computer

USB-C port on Apple Silicon Macs may require manual unplugging and replugging of the lightning cable after checkm8 exploit. This problem may be solved by connecting via USB hub, though extensions can vary.

Building

Building is going to be a bit convoluted for each platform, each having their own unique specifications, but the best reference for building should be looking at how GitHub actions does it.

# Supported params:
#  GUI support                              (0 default):
#   WITH_GUI=1
#  TUI support                              (0 default):
#   WITH_TUI=1
#  Default ramdisk                          (1 default):
#   WITH_RAMDISK=1
#  Default overlay                          (1 default):
#   WITH_BINPACK=1
#  Compile statically                       (0 default):
#   WITH_STATIC=0
#  Compile using libciderra1n as backend    (0 default):
#   WITH_CIDERRAIN=0
#  Debug or release build                   ("Debug" default):
#   BUILD_TYPE="Release"

When building, many precompiled artifacts are embedded inside of the program. Such as, PongoOS, jbinit, and the Loader.

Make sure these files are present.
NOTE: PongoOS BIN and KPF is absolutely required when building.
