Revision as of 00:59, 23 January 2021

Non-Secure Kernel Boot Loader (NSKBL) is a Non-Secure world program that performs eMMC setup, base kernel modules loading, etc. during PSVita boot.

Module

The NSKBL 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


/* Many pointers are NSKBL heap relationships */
typedef struct SceNskblSysrootInfo { // size is at least 0xC8 on FW 3.60
	SceUID unk_0x00; // maybe some PID. ex: 0x10089

	void *unk_0xC4;
	// more...?
} SceNskblSysrootInfo; // 3.60

SceNskblSysrootInfo *nskbl_sysroot_info = (SceNskblSysrootInfo *)(0x51000000 + 0x138980); // 3.60
