PS3 Atempting to create a Lv2diag.self that can dump both nor and nand

[zecoxao]

Hey, so, i am in need of some help here. I want to create a Lv2diag.self that dumps the flash of a console between 1.00 and 3.55 (in this case the target is DoublesAdvocate 1.00 never dumped Japanese PS3)

I need some assistance from the top devs, @mysis , @bguerville , @esc0rtd3w , @M4j0r among others. Does anyone know if this is possible, and if so, could throw a hand or two? Thanks

Yea should be possible

Yea should be possible

Do you know how? I'm using sguerrini's dumper as a test but it's not working

I also didn't got it to work when I was doing tests and have given up. maybe using spu toolchain? I was recommended on pshax using spu toolchain to make custom lv2diag

It's a ppu program so i doubt spu toolchain is the answer

"if you resign them and they don't include any vsh stuff they work as lv2diag"

@haxxxen @mysis there is a tiny exit Lv2diag created by CrashSerious on brewology. it writes to a log, does a single beep and exits FSM

some progress:
Jaicrab created Preloader Lv2diag.self, which can dump and restore both nand, nor, and dev_flash.
However, there is an issue. when dumping the flash on 1.02 or 1.01, the core os partitions are missing (@M4j0r tested this on his 1.02 downgraded CECHB and 1.01 DECR-1000). they aren't missing in 3.50 or 3.55 but they are missing on those firmwares. So we need the exact toolchain to progress. As it turns out, the Lv2diags created by Jaicrab and CrashSerious use a different .crt0 and libc than the ones used on the PSL1GHT v2 or even the official sdk. which means that we must find out exactly which ones were used (i suspect that the v1 psl1ght was used to program these files)
All this info was reported to me by @M4j0r , who conducted the tests on friday and saturday.

When CrashSerious and Jaicrab were active in the PS3 Scene i believe that would of been prior to v2 of pslight but i could be wrong..

Did you manage to get it working or still need help?
