Zerocat Project Template – v0.0.23 released!

This version comes with a refined skeleton for improved HTML documentation output. A dedicated dropdown button, labeled “GNU Guix Environment”, provides detailed information about a project’s shell environment on GNU Guix System.

All Zerocat projects have been updated accordingly and offer the same type of documentation structure, while maintaining each project’s requirements of development software.

The management of multiple free software projects with their demands for individual toolchains is now made easy. Zerocat uses it as a proof of concept to build this website :-)

2023/02/25

Zerocat Project Template – v0.0.22 released!

This project skeleton supports easy toolchain setup in one go¹, thanks to GNU Guix’ ability to travel in time. If a tool fails after upgrading the project’s guix channel information, just restore that information and your approved, reliable toolchain environment will again be available and keep you productive :-)

Chipflasher: New PCB Design Sources released!

Branch flashrom-interface, commit fa7ba6995:

Chipflasher board v2 Design Sources are now publically available.

Hardware Design Sources are licensed under CERN Open Hardware License Version 2 – Strongly Reciprocal.

You may redistribute and modify the sources and make products using it under the terms of the CERN-OHL-S v2 or any later version.

This ensures that the source location of the Chipflasher, being engraved into the copper of the PCB, remains with the physical product and its derivatives ;-)

Until new, physical PCBs are available, these sources come with status UNTESTED.

2022/07/21

Chipflasher’s Flashrom Interface: Faster SPI Routines

Branch flashrom-interface, commit f8919500: The SPI bus is now accessed via PASM routines, which provide much better clock rates. Eight bits of data read/write is done with 5MHz. Other bit lengths are still transferred at good clock rates, such like 4MHz (read) and 3.33MHz (write).

See SPI Clock Speed with Flashrom for some pretty oscilloscope snapshots.

Ready to fly: Chipflasher’s Flashrom Interface is Up and Running

I am very pleased to announce herewith the successful release of Chipflasher’s Flashrom Interface. The project’s core milestone #3(7) is now done. It links a widely used free software project to hardware of a free design, even down to chip level.

I receive great support from OSE-Germany e.V. and associated fellows, as well as from Michiel Leenaars from the NLnet Foundation. I am very grateful to meet your friendly companionship and encouragement!

Now have fun to see the documentation: Chipflasher Flashrom Interface

More Laptops in Shop

Occasionally, ThinkPads come with flash chips that have volatile registers. The chipflasher now handles these types more reliably with kick2, the second firmware approach. Selected devices move into the shop:

At power-up, volatile registers are set into Software Protection Mode (SPM) by the flash itself, that is why Hardware Protection Mode (HPM) cannot be applied via jumper.

New Logotypes and Icons

Zerocat used to use the last letter of the latin alphabet for its icons, in conjunction with an emphasized exclamation mark. However, we have to face the fact that this letter has been hijacked. As a consequence, we now drop that letter and use different icons as a clear act of sympathy and empowerment for the ukrainian people and for peace.

It’s always satisfying to modify and free yet another Thinkpad: digging deeper, finding tweaks, making firmware replacement even simpler. My T430 has been flashed without even touching the fan! Let’s elaborate clipless procedures for more models, come and join the Zerocat Flash Access project!

Hurray, the year is over!

It was a difficult year for me and many others, so we do not need to make a resumé! Let’s focus on the next steps instead – I can’t wait to make them all come true in 2022:

  1. Zerocat Chipflasher Flashrom Interface made great progress and continues to receive funding from the NLnet foundation! The project is now starting with core milestone #3(7).
  2. Boost production of the latest free software laptops. In 2022 we will continue to provide the best quality laptops and promote their use. Current trends in digital surveillance, social control and pressure, makes this more relevant than ever. We are all in urgent need of private, secure communication equipment and all-purpose computers.
  3. Launch of Zerocat’s crowd funding page. As we move into many new projects, we need funds to scale up!

I wish you all the very best for the new year and invite you to stop using compromised hardware and smartphones, throw them away! The sooner we liberate ourselves from that crap, the better we can save families, neighboorhoods and societies.

Zerocat Chipflasher v0.6.1 released!

This is a major step! The interface to the project’s connect utility has greatly been improved. You have full access to chips’ configuration registers and their protection and lock bits.

As an exciting, special feature, it also lets you access and lock the Secured One-Time-Programmable Regions, often found on ThinkPads. Lock the regions, before someone else will do it!

Furthermore, end-of-write-cycle detection can be switched from polling to timeout – This eases flashing of ThinkPad models T530 and W530.

Please note that Zerocat Coreboot Machines has been advanced, too. It now ships version v0.16.2.

Last but not least, all project documentations support inline images – I very much hope you like that!

--- Kai Mertens

2021/10/26

Zerocat Coreboot Machines v0.16.0 released!

The project has been cleaned up, it should be very easy to use now. Special thanks to those hackers that have supplied hardware and that have tried the project on their own – you helped to improve it! See NEWS.

Free designs become even more important these times, ...

... as we see that societies rely on solidarité rather than on commercial market in cases of emergency. The right way to go is to request free designs not only for software, hardware and seeds, but for immunology vaccine as well.
