Yes, and there are long stories behind it.

We developed them for a customer's digital security key, similar to the "X.509 thread" in CAE. However, some hackers got hold of it and turn them into PS3 unkey, since Sony stopped supporting Linux. They were trying to re-enable Linux on their PS3, which is still in progress. Other PS3 users start using them to backup their blue-ray disc onto the hard drive. Some are running their games on broken blue- ray drive, which is the most fragile part of the PS3.

The way Sony (QA/QC people) and the hackers do are very interesting. I will follow up with another post with details. I need to go do something else first.

er.

that

Follow-up:

The "Yes" is answering the PS3 Jail-Breaking part, not "WinAVR as crap". Gcc, where WinAVR is derived, is great software.

Before 2010: Sony's factories use the buffer overflow technique to QA/QC/install the system. Upon power up, immediately reject the blue-ray disc. This will cause the system to look for another device on USB (most likely a 4-port hub). However, if the device emulates a 6-port hub, it will cause a buffer overflow and start executing on the stack. Sony itself use this to control the manufacturing.

Early 2010: Someone got the detail information from the factories and started selling USB devices to boot Linux, as well as backing up blue-ray discs.

Sept 2010: Open source psgroove project released to the public, using the Atmel At90usb162 USB micro. Many other micros and devices were ported as well. Psgroove injects a 4K boot loader into the PS3. However, additional programs need to be installed on the hard drive or other device for Linux.

Mid-Sept 2010: Sony released on-line updates to stop the exploit. Sony urges retailers such as Best Buy and Walmart to upgrade (more like downgrade) the PS3 before selling. Some will do the favor with fee from the consumer. Sony should have paid the retailers to do so.

Today: Many small shops around the world can restore the PS3 Flash to version

3.15. Linux developers are using the UDIP/UKEY with custom SD/CF/ATA devices.
