WANTED: ST20 TOOLCHAIN, COMPILER AND PATCHES

The ST20 is a microprocessor used by STMicroelectronics (formerly SGS-Thomson) in ASICs for Set-Top-Boxes from the late 90's to the mid 2000's.

It is a CPU based off of the old transputer (computer on a chip) and it is programmable in C with a toolchain. Unfortunately, due to the closed nature of the chip, the toolchains have been lost to time. The only parts I found was a document that shows how to use the "ST20 Embedded Toolset".

I have also found a french blogpost from 2015, in which someone managed to hack their box to run custom code and also references a patch for one of the ASICs alongside the toolkit.

The following is a list of the files I am looking for

• stm-st20.231-2.3.1-MSWin32-x86.exe (Windows toolchain)
• stm-st20.231-2.3.1-1.i386.rpm (Linux toolchain packaged for RedHat)
• stm-st20.231-2.3.1-MSWin32-x86-patch-2.exe (patch for Windows toolchain)
• Unconfirmed patches for Linux

Here is also a list of some of the reference materials I have found

• PDF documenting the ST20 toolchain
• French blogpost doccumenting the modification of a reciever using this CPU
• Backup of the file index of the (now dead) FTP server

If anyone manages to find some of these files, please send me an email with the files attached or with links to files in a cloud sharing service like WeTransfer, Google Drive, MEGA, MediaFire or Archive(dot)org. I am going to archive them and include your name as credit. (if wanted, I can also credit the user anonimously, with no public name/alias)

Thank you for reading this
