FPGA / GateMateA1-EVB-2M - use flash ...
Last post by mattis.lundberg@aimpoint. - August 13, 2026, 12:38:28 PMIs there a better way to utilize the flash memory than:
1. Disconnect the card.
2. Setting CFG_SET1 to ON-ON-OFF-OFF.
3. Connect the card.
4. Write to flash using openFPGALoader --board olimex_gatemateevb --write-flash blinky.bit
5. Disconnect the card.
6. Setting CFG_SET1 to OFF-OFF-OFF-OFF.
7. Connect the card and observe the stored configuration run.

A20 / difference between A20-OLinuXi...
Last post by oeren - August 11, 2026, 06:05:23 PMWhat is the 16MB SPI flash memory for? Is it correct that you can install a bootloader on the 16MB SPI flash memory?
If you decide to leave the 16MB SPI flash memory empty, will the A20-OLinuXino-LIME2-s16M then work the same way as the A20-OLinuXino-LIME2? Thank you.

A20 / Working Linux driver for USB-W...
Last post by sasha2002 - August 10, 2026, 01:35:04 PMHi,
Currently bought USB-WIFI6-5G-ANT
Tested it on latest debian, it's detected as
ID 350b:f179 ZTOP ztop CDROM
after " eject /dev/sr0" it's detected as
ID 350b:9612 ZTOP 802.11ax 2x2 WLAN Adapter
Can't found any working driver for it.
Anyone have it?
It's strange but Olimex sell it and this cards support only windows, meh.

A20 / LIME2-4GB dead or not?
Last post by philderv - August 05, 2026, 05:41:22 PMHello everybody,
This is my first message on this forum, I'm a French user. So, English is not my first language, sorry if I don't express myself very well.
Ok, here is the issue.
11 years ago, I bought an A20-OLinuXino-LIME2-4GB (Hardware Rev. C) and until yesterday, I used it to host an Debian/Yunohost Mail Server. No problem with that.
Also, I used it with a battery, this model: BATTERY-LIPO6600mAh
Yesterday, I noticed that server crashed, it seems: no display in HDMI (LCD screen Asus VE228H).
I stopped everything.
Brutally. I mean, unplugged power cable.
But, when I tried to start again the Debian OS on my SDCard, nothing happened.
Power LED was fix red, with LED orange for battery, fix too.
No HDMI display, no activity on ETH LED, and, of course, nothing on USB Keyboard (standard).
What I tried
- boot the LIME2 with only: battery + HDMI cable to LCD Screen Assus VE228H (no SDCard, no USB, no ETH cable) = nothing - no display - fail
- boot the LIME2 with same config as previous, but:
=> push POWER button: battery LED blinking 1 time only after 5 seconds of pushing button;
=> push RESET button: battery LED go dark during 3 - 4 seconds, then become again orange fix, if I release button;
=> push RECOVERY button: nothing.
Yesterday, I tried with another power supply adapter, with Output 12V / 1A / 12 W, and only with HDMI plugged and with/without SDCard: LED power was red fix / battery LED was orange blinking.
But no avail, no display, no boot.
Tee board seems, visibly, no damaged.
What do you think?
So, what I can do now to test if my LIME2 is alive or dead?
I know it was old, and I can admit it was completely dead.
Looking forward to hearing from you.
Regards.

A64 / Re: Overheating on mainline Li...
Last post by Roman - August 04, 2026, 11:13:17 AMI have found a heatsink that seems to correspond to the requirements slightly better than other commmon small heatsinks (ICK BGA 15 x 15 x 14 from Fischer Elektronik). It is the right size and is anodised, which is a good thing for a heatsink in an enclosure, right?
Now, I wonder what thermal interface do I need. To smooth the load spikes, the pad has to transfer heat quickly. The common options that I see are rated 0.4 W/m·K and 1.5 W/m·K. The earlier may be not enough to smooth the temperature spikes, or could it be enough? Any advice on what thermal interface A64 might require?

ESP32 / Using High Power Output form E...
Last post by yakatz - August 03, 2026, 09:02:00 PMI am looking at using an ESP32-POE2 to control a water valve that takes 12v or 24v. I have worked with 5v output switching, but how would you do the same thing with the higher voltage output?

A20 / Re: My Micro won't boot from M...
Last post by buntubaby - July 31, 2026, 10:09:45 PMHi LibOlimex,
A 5V adapter for the USB-OTG port should be able to power the board, as the manual states under heading 2.3 ;
"There are four possible ways of powering A20-OLinuXino-MICRO – via external supply providing 7-24V DC3 at the power jack, from 5V USB port via USB_OTG connector, from 3.7V Li-Po battery via the LIPO_BAT connector, from 5V source applied to 5VEXT test pad at the bottom of the board and any GND."
... and to be fair it also states "The best practice is not to count on the mini USB-OTG as a single power source!"
I've tried the problematic SY0612E-CHINA on another A20-OLinuXino-MICRO with just ethernet connected, and it would not boot either. So, bye-bye to the SY0612E-CHINA!
Thanks for your tips, I'll be looking for a 12V1A adapter.

Neo6502 / Re: Apple II emulator
Last post by LubOlimex - July 31, 2026, 09:25:31 AMDid you read and follow my advice from the previous post (aka you also need to have USB flash drive with Total Replay):
1. To use the apple emulator, you also need to format a USB flash drive with Total Replay. You can find it here:
https://ftp.olimex.com/Neo6502/Total%20Replay%20v5.1.hdv
Just place it in main folder of the USB flash drive and after that plug the USB flash drive in the Neo6502 that is prepared with apple2e-5.uf2. Finally power the Neo6502.
2. If it still doesn't work try preparing the board with the original apple2 binary:
https://ftp.olimex.com/Neo6502/old-uf2/apple2_800x600_400MHz.uf2

Neo6502 / Re: Apple II emulator
Last post by egrath - July 30, 2026, 06:03:03 PMHi,
sorry to revive an old thread. I'm suffering getting the Apple II emulator running at all...
I'm copying the uf2 file over to the Pico's flash by starting in bootloader mode. About 1 second after the copying has finished, the drive disappears, so my assumption is that the flash succeeded.
However, when plugging in the Neo6502 to a display, the screen stays black.
Tried the following files, both with the same result (no success):
https://ftp.olimex.com/Neo6502/apple2e-5.uf2
uf2 inside the following archive:
https://ftp.olimex.com/Neo6502/blank_disk_for_apple2e_code_development_apple2e_ProDOS_2_4_3.zip
I verified that my board is good by flashing the official Morpheus firmware (v1.0.0) which works flawless.
Any ideas? Do I need anything else to get started? I'm just interesting in running AppleSoft BASIC and ProDOS on the Neo6502.
With kind regards,
Egon
