Initial impressions of the #olimex #gatemate
The good:
* Very nice with another open toolchain FPGA board.
* Open source hardware
* Build in programmer and UART interface
* Almost all the tools for programming the board is available in Debian unstable
The bad:
* The Olimex supplied documentation is very very minimal, almost non existing
Nitpicks:
I have yet to find a way for resetting though JTAG_RST.
As a result I currently have to press the button for consistent programming success.
Tiny Shader running on the GateMateA1-EVB with an open source toolchain 🎉
Originally this design was created for Tiny Tapeout, more information can be found here: https://github.com/mole99/tt06-tiny-shader
And if you want to see the TT06 chip in action, take a look at this thread: https://fosstodon.org/@mole99/113730908871370284
I've got myself a new toy 🙌
This is the GateMateA1-EVB from Olimex, an FPGA dev board containing the GateMate CCGM1A1 with 20480 CPEs.
Now that initial nextpnr support for the chip has been merged, it is possible to program it with a fully open source toolchain 🎉
Synthesis with Yosys, place and route with nextpnr, bitstream packing with gmpack and finally upload to the board with openFPGALoader!
That meant I just had to get one, and two days later it arrived!

I am so glad to report that Cologne Chip will be sponsoring the CERN 2025 FPGA conference. The email announcement just arrived.
Very motivating.

Mecrisp Ice has a couple of 32 bit soft core stack machines, but I have not paid close attention to them. Music is fine with 16 bits. Real world control is usually at 20-22 bits. Video is 24 bits. FPGA real estate is both expensive, and slows things, so not much reason to go beyond 24 bits. Sadly I do not know of any fpgA with 24 bit memory. #GateMate has 20 bit memory, on a $50 board. Most interesting;

Rumor has it that #CologneChips will be presenting #GateMate at the Space Components Confeence in May 2025.
Cologne Chips writes about the new #olimex #gatemate add on boards.

Allez, il est l'heure d'aller se coucher. On verra la suite quand il fera jour.

Was not easy as p_r is doing a bad job, but at some point with moving LEDs assign I got USB host working on @olimex #GateMate-EVB Still needs lots of work to be usable, but at least I know HW is ok.
The person who is porting #Yosys #NextPrN to #Gatemate on the #olimex board, is discussing his work on this Discord channel. #fpga #digitalmath #addition #multiplication #gaussianlogarithms.
