The only thing left to try is "teres_armbian_v1.0_preliminary.zip".

That being said I am not sure if the hardware is sufficient for smooth YouTube experience especially for higher bitrate.

The best bet for heavy video decoding tasks like this is to see if somebody got the LibreElec working for the A64 chip or Teres laptop. My personal experience for video playback with LibreElec and A20 boards was the best.

TERES DIY Laptop / Every Distro/Image has another...

Last post by hmk - June 02, 2026, 05:16:24 PM

Just wondering, has everybody managed to find a Distro/Image that is pretty much usable out of the box?

- Latest Armbian Ubuntu (https://armbian.com/boards/olimex-teres-a64): No sound, no trackpad.
- xenial-teres-bspkernel-20190121_144941_EET-1_hdmi_out_v1_5.zip: Sluggish (on microSD), takes up plenty of disk space (and you run out quickly when trying upgrades), FireFox very old and not supported by YouTube, upgrading breaks the system and FireFox.
- Android (android_teres_rev4.zip): Ancient, no sound (have not tried it out, but reported in this forum).

All in all a pretty tedious experience. I only wanted to have a Laptop with sound that can play YouTube videos and have a running slideshow (with Google Docs).

For xenial-teres-bspkernel-20190121_144941_EET-1_hdmi_out_v1_5
it worked for me to update/install chromium-browser (and to remove firefox).
(It is possible to play YT videos, for instance.)

Never reinstall a working system ...

Well, yes, but with this browser you cannot use YouTube, Google says it's not supported. (Cannot blame Google here, IMHO.)

New Product Ideas / Re: can a lime 2 or pico 2 xxl...

The rpi zero w requires non free software in order to work.

Quoting from a Stack Exchange answer for context.

The Pi Zero uses the BCM2835 system-on-a-chip, which combines a CPU and a VideoCore 4 GPU ... the GPU bootstraps the CPU and loads a kernel into it ... the firmware required for the GPU is from closed source.

In contrast, A20-OLinuXino-LIME2 does not require any proprietary binary blobs to boot. For example, Guix System, which is compliant with the Free System Distribution Guidelines (FSDG), is known to run on it.

However, A20-OLinuXino-LIME2 is much larger, it is twice as wide as Raspberry Pi Zero W. Would it be possible for Open Printer to fit it in their design?

PICO2-XXL is a "re-design of the popular 'Raspberry Pi Pico 2'", so it does not run GNU/Linux. Could Open Printer still use it?

New Products release / Interesting Project: Turn Wire...

Last post by olimex - June 01, 2026, 03:23:08 PM

https://olimex.wordpress.com/2026/06/01/interesting-project-turn-ethernet-poe-into-a-wi-fi-hotspot-with-esp32-poe-iso/

This open-source project transforms an ESP32-POE or ESP32-POE-ISO into a compact Wi-Fi NAT router, allowing you to create a wireless hotspot from a wired Ethernet connection while powering everything via PoE.

✅ Ethernet → Wi-Fi NAT
✅ Powered over Ethernet (PoE)
✅ Arduino-based
✅ Open Source

Default AP:
📶 SSID: OLIMEX-ESP32-POE-ISO
🔑 Password: 12345678

Debug page:
🌐 http://192.168.4.1/

A handy solution for IoT, industrial deployments, remote installations, and any project where you need Wi-Fi from a wired network without adding a dedicated router.

STMP1 / Re: Load M4 firmware

Last post by LubOlimex - June 01, 2026, 10:09:47 AM

JTAG and SWD should be possible. You might need to force the no bootloader mode via SMT jumpers. Maybe some of the guys in the forum have more experience with it, we haven't tested it here. My advice is to also check the official STM forums (since the pins are free and available), maybe there is more info.

STMP1 / Re: Load M4 firmware

Last post by dry - May 29, 2026, 05:26:49 PM

@LubOlimex:

 On the related note, is it possible to debug through JTAG that Cortex-M4 side? If I'm writing custom firmware.

I see JTAG lines, unsure if its same lines for all cores on this asmp chip? Anyone successfully debugged with JTAG (e.g. Segger, Olimex) that  M4 core?

If you only have 12V DC consider driving it down to 5V D

Thanks LubOlimex, I've asked this because I'm planning to do an automotive related prototype with this board, and hoped for luck I can power it from 12V battery.  (I will get your  ps adapter)

(maybe simply copy what we've done for the CAN around the SIT1050T)

.. I'm testing a couple of transceivers on my own board, so probably thinking to do a small like extension board or a connetor to somehow plug/connect into this STMP157 olinuxino's GPIOs, unsure yet. May be also cut-out hole for second  CAN connector on the side of that box - unsure best way.
