What changed compared to previous FW version
|
| 0.940 |
Changed SKBL base physical address to 0x40040000 from 0x50000000. NSKBL is now stored in kernel_boot_loader.self segment 3 instead of SKBL .text, and loaded (ARZL-compressed) at 0x50000000.
Changed the early boot stack base addresses from 0x500Ex000 to 0x400ExC00. Undef/Abort/IRQ/FIQ stack are no longer separated.
Resuming on Kermit ES1 is no longer supported (sceKernelAssert(0)).

| 0.995 |
Unknown.

| 0.996 |
Changed SKBL base physical address to 0x40020000 from 0x40040000.
|
| 3.36 |
Unknown
|
| 3.50 |
Initial stack base changed (+ 0x100).
Something in the function has changed (see function at: 3.50:0x40020438).
Removed some register writing (see function at: 3.36:0x4002066c/3.50:0x40020668).

These functions are at different offsets than those of SceTzs modules.
Offsets are relative to SKBL text segment base address. See Secure DRAM.
