166w ago - Nintendo Wii developer Marcan has been sharing updates via Twitter on his progress with a PS3 Linux bootloader, one that is currently working on PlayStation 3 Firmware 3.41 (including on the PS3 Slim) and now named AsbestOS.
I bet you've never seen a Linux kernel say this: [ 0.000000] PS3 firmware version 3.4.1
Wasted like an hour debugging a bootwrapper that was working perfectly, except noone documents this stuff. dtbImage.ps3 != zImage.ps3
That wasn't too bad. Threads caught.
Next headache: catching *both* CPU threads from lv2.
AsbestOS (yeah, I'm calling it that) now works on the PS3 Slim (still doesn't quite boot Linux, though)
I can TFTP-load a kernel now, though it doesn't exactly boot yet. More tomorrow, hopefully.
There are two stages. Stage1 replaces the usual psjb payload (2kB or so) and loads stage2 via USB (30kB currently)
The Teensy will NOT work without external mem (32K Flash). The Teensy++ and the AT90USBKEY SHOULD be enough (128K Flash).
By the way, if anyone wants to run this Linux loader from a hardware dongle, make sure you get something with at least 64k of storage!
IP stack = done (lwIP FTW). 64 bytes from ps3 (192.168.3.60): icmp_req=1 ttl=255 time=0.361 ms
I suck at names. Help me name a usb-exploit PS3 Linux bootloader? All i came up with so far is lv2ate ("levitate") and AnotherOS.
Last tweet brought to you by LPAR, VAS, HTAB, TLB, SLB, DMA, BI, PU, RM, PME, HPTE, VSID, ESID, AVPN, RPN, WIMG, GELIC, and, of course, LV1.
http://is.gd/fj0dK sent from a USB lv2 payload using raw lv1 syscalls. And now I can finally go to sleep today.
Ha, Linux got owned by *exactly* the same bug that the 360 hypervisor had: comparing 32b of a system call no., then using 64b. (via tmbinc)"
