NSKBL is a program that performs emmc setup, base kernel module loading, etc. during PSVita boot.

Module

The non-secure kernel bootloader contains an embedded and likely stripped version of SceSysmem, SceKernelModulemgr, SceSblSmschedProxy, SceExcpmgr, SceKernelIntrMgr, SceSblAuthMgr, SceProcessmgr (maybe), SceSdif, SceIofilemgr (Simple version?), and some other core drivers.

How to debug NSKBL

NSKBL supports sd0: for debugging.

sysroot->boot_type_indicator_1:0x40000 is required.

Types
