UEXT / Re: MOD-IRDA faulty ?
Last post by LubOlimex - January 09, 2026, 03:31:43 PMIndeed, thank you for your research. I got back to testing this and the distance is up to 2.5-3m which is unexpectedly low, we determined that the LED is simply small for better distance. The engineers wanted to save space but it is not worth it. In future we would switch to 5mm IR333-A, which seems to improve the range to around 10m which is much better. Thank you for reporting this.

A20 / Re: A20 Board Power Consumptio...
Last post by silencebeneath - January 09, 2026, 09:42:38 AMQuote from: annasm on December 15, 2025, 06:42:52 AMHi everyone, I'm using an A20 OLinuXino board for a low-power project. I'd like to know the typical power consumption of the board when it's in sleep or idle mode with no peripherals connected. Are there any recommended settings or tweaks to minimize power usage in this state? Thanks in advance!As far as I know, the A20 processor isn't made to use as little electricity as possible. Still, I'm curious whether there are any system settings or changes that could aid lower power use in this scenario.

A20 / Booting A20 OLinuXino from USB
Last post by sophia2005 - January 08, 2026, 11:14:19 AMHello everyone,
I'm trying to boot my OLinuXino A20 from a USB drive instead of an SD card, but it's not working. I've tried changing settings in u-boot, but the device still doesn't detect the USB. Has anyone successfully booted the A20 from a USB drive? I would appreciate a detailed guide or the necessary steps to configure U-Boot and the filesystem on the USB.

Last post by sulllymin - January 08, 2026, 10:04:29 AMGood question—power draw in idle can really make or break low-power projects. Tuning sleep states and disabling unused interfaces usually helps a lot.

FPGA / toolchain for GateMateA1-EVB
Last post by mastupristi - January 04, 2026, 06:12:38 PMHello,
The document ug1002 "Toolchain Installation User Guide" is listed on your website.
Inside I find:
Following the directions, however, I find this:
https://colognechip.com/programmable-logic/gatemate/toolchain/
It seems that document ug1002 describes the legacy toolchain called cc-toolchain-linux.tar.gz,
but as you can see on the page, the most recent toolchain is oss-cad-suite-linux.
However, I cannot find any usable examples in this new toolchain.
I found some examples (perhaps) that could be useful here: https://github.com/YosysHQ/prjpeppercorn-test-cases
What do you think about using the new toolchain?
Do you have any quick guides on this? Or even just suggestions?
regards
Max

FPGA / Re: Questions about GateMateA1...
Last post by mastupristi - January 04, 2026, 05:40:57 PMHi,
I found this: https://youtu.be/lMUQplZXPoM?si=BMzlcv0eBE_oDg0y
Where they referred to the 'blink' example.
It is present in the toolchain, but it needs to be edited to change the pin definition, which is set to CCGM1A1-E1 by default.
I searched on GitHub and found a couple of repositories that contain the blink example with the pin definition for Olimex:
I hope this helps others.
regards
QuoteNo idea. Some bit file was provided by Cologne community if I remember correct. The software usage is detailed here: https://github.com/OLIMEX/GateMateA1-EVB/blob/main/SOFTWARE/ug1002-toolchain-install-latest.pdf

Neo6502 / Re: Creating ARCADE games for ...
Last post by Maarten van Druten - December 24, 2025, 06:02:09 PMWhile trying to build the game I found out problems,
The makefile uses ca65 (cc65 assembler) but the source code was written in 64tass syntax!
So I am fixing this now and will upload the right files on github soon

Neo6502 / Re: Creating ARCADE games for ...
Last post by Maarten van Druten - December 23, 2025, 08:31:26 AMI posted my files on GitHub:
https://github.com/MishaOpenArcadeSystem/Gaudens-Machina-EX
Who can help me to accomplish following goals:
1 - Make this game work on Olimex NEO6502
2 - If the game works create a manual how to configure the Olimex NEO6502
so it boots automatically into the game when turned on
