Last post by LubOlimex - December 08, 2025, 10:34:38 AM1. Thanks for notice. It is now uploaded.
2. No 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
3. Yes, we published the uf2 file that we ship the boards with, here: https://github.com/OLIMEX/GateMateA1-EVB/tree/main/SOFTWARE/dirtyJtag
I believe we took it from here: https://github.com/colognechip/gatemate_ila/tree/main/Olimex_DirtyJTAG_firmware
It is popular board, you can find a lot of projects online, like check this one:

UEXT / Re: MOD-IRDA faulty ?
Last post by SirExie - December 08, 2025, 10:00:00 AMThankyou LubOlimex,
I think the question was - is there any way of testing the MOD-IRDA outside the code ? like, just electrically ?
In the meantime, I'll try compiling the demo and see if I can get it to transmit something useful.

A20 / Re: Question about OLinuXino b...
Last post by LubOlimex - December 08, 2025, 09:15:54 AMWhich A20 OLinuXino board more specifically? These have different requirements. Is it MICRO, LIME, LIME2, SOM, BASE-SOM.... What is your setup? What do you have connected to it?

UEXT / Re: MOD-IRDA faulty ?
Last post by LubOlimex - December 08, 2025, 09:13:51 AMThe problem is somewhere in your software. We've used MOD-IRDA with ESP32-POE boards in the past, specifically in this big web-server demo:

UEXT / MOD-IRDA faulty ?
Last post by SirExie - December 06, 2025, 02:49:38 PMHi Folks,
I have a MOD-IRDA I'm using with an ESP32-POE-ISO-IND. The UEXT port makes this simple, but I have not been able to transmit via the module.
I'm using ESPHome, and I have it set to use GPIO4, but the client device never responds. I tried filming with the phone camera, but the IR is not visible.
I then tested the UEXT port using a Saleae, and all the pins work fine and I could even decode IRDA.
So my final test was ti check resistance across the the IR LED, and testing both polarities at 200 Ohm was an open circuit. Not what I expected, so I think the LED is faulty ?
No point posting it back, the local electronics shop have 3mm IR LED's for $1.50 so I'll try swapping this out first and see how I go.
How likely is it that this is the problem ? is there any other test I can do ?

FPGA / Questions about GateMateA1-EVB...
Last post by mastupristi - December 06, 2025, 12:04:51 PMHello,
I have some question on GateMateA1-EVB-2M.
best regards
Max
I have some question on GateMateA1-EVB-2M.
- I bought the card and saw that it is Rev C. Here https://github.com/OLIMEX/GateMateA1-EVB/tree/main/HARDWARE there are only Rev. A and B. Can you also publish Rev. C?
- Where can I find the VHDL or Verolog sources for the FPGA configuration with which the board is shipped?
- DirtyJtag (https://github.com/OLIMEX/GateMateA1-EVB/tree/main/SOFTWARE/dirtyJtag) is the Firmware that run on RP2040, isn't it?
best regards
Max

Last post by ameero95 - December 03, 2025, 09:12:39 PMHello LubOlimex,
I got that answer from emailing their support. I have requested for the firmware on the forums (https://forums.quectel.com/t/how-to-get-quectel-standard-firmware/36353/64) aswell. I'll wait for a reply from one of their support people. Thanks again.
Quote from: LubOlimex on December 03, 2025, 01:16:07 PMDid you write e-mail to the support or post in the forums? Please post in the Quectel forums and link me the forum thread where you requested the firmware.
