NSKBL
NSBL is a program that performs emmc setup, base kernel module loading, etc. when vita boot
Module
The non-secure kernel bootloader contains an embedded and likely stripped version of SceSysmem, SceKernelModulemgr, SceSblSmschedProxy, SceExcpmgr, SceKernelIntrMgr, SceProcessmgr (maybe), SceSdif, SceIofilemgr (Simple version?), and some other core drivers.
How to debug NSBL
NSBL reads from sd0: instead, if a read error(?) Occurs in os0: during vita startup.
but, in order to generate os0: read errors, os0: must be damaged in some way, so there must be a way to physically recover vita.
