A64 / Re: Bookworm upgrade availabil...
Last post by mossroy - September 05, 2025, 03:45:22 PMNow that Debian 13 (Trixie) has been released, I've tested again the Debian Installer on the Olinuxino devices I have:
- Olinuxino A20-OLinuXino-MICRO: can be installed by Debian Trixie installer (with https://deb.debian.org/debian/dists/stable/main/installer-armhf/current/images/netboot/SD-card-images/). I did not test for long, but it seems to be stable
- Olinuxino A64-OLinuXino-2Ge8G-IND: The Debian installer https://deb.debian.org/debian/dists/stable/main/installer-arm64/current/images/netboot/SD-card-images/ does not start (stuck on "Booting kernel...". With "earlycon" bootarg, it seems to show it crashes on an mmc step). After replacing the dtb by the one from Olimex latest image, I could run the installer properly, and install it on the SDcard. However, I did not manage to make it start afterwards (stuck on "Booting kernel..." too, but the "earlycon" trick does not seem to give more detail)
So the problem remains with my A64 (2Ge8G) boards.
I don't care about its eMMC: is there a software or hardware solution to make it ignored? Hopefully it would help installing a regular Debian on it

Last post by LubOlimex - September 05, 2025, 11:20:35 AMThe instructions I published above were for the buster image, where DTC edit is possible via the armbian-config. Maybe test with the buster image instead. The archive "RK3328-SOM-buster-20220122-002412.img.7z" can be found at the ftp.
Maybe armbian changed the way to edit DTC in the latest releases
Edit: I will investigate further when I have the time. Thanks for pointing the serial 1 is serial@ff120000 I have edited my previous post.

A13 / Tips and experiences with A13 ...
Last post by michaelarrington - September 05, 2025, 05:33:00 AMHello Olimex community,
I've recently started working with the Olimex A13 board (Cortex-A8, 1GHz, 512MB RAM, 4GB Flash, VGA, SD-card, 3x USB host, WIFI, 72 GPIOs, UEXT, Audio In/Out) and I'm really enjoying exploring its capabilities.
I would like to ask for some advice and hear about your experiences: PolyTrack
Which Linux
I think the A13 is still a very interesting board for lightweight projects, and I'd love to learn from the community about how to optimize it for real-world use cases.
Looking forward to your input and sharing of experiences!
I really appreciate any help you can provide.

I would like to ask for some advice and hear about your experiences: PolyTrack
Which Linux
- images are currently the most stable for A13?
- Any tips for getting WiFi performance more reliable?
- Has anyone successfully used the 72 GPIOs for larger projects (e.g., sensor arrays or custom peripherals)?
- What are the best practices when working with UEXT modules on this board?
- Any known issues with audio in/out, and how to fix or improve it?

A20 / Best practices to optimize A20...
Last post by jeffreestar - September 05, 2025, 05:27:42 AMHello everyone,
I've been experimenting with the Olimex A20 board (Cortex-A7, Dual Core, 1 GHz, DDR3 1 GB, 4 GB NAND, HDMI, SATA, Gigabit Ethernet, LCD, GPIOs) for some projects, and I would like to hear your experiences and tips.
Specifically, I'm interested in: that's not my neighbor
Best Linux distributions (Armbian, Debian, etc.) that run most stably on A20.
Performance tuning tricks for SATA speed and Gigabit Ethernet throughput.
Recommended approaches for GPIO usage in custom applications.
Any issues you faced with HDMI output or LCD integration, and how you solved them.
I'm currently testing with Debian-based images, but I wonder if others here have found better performance with specific kernels or custom builds.
Looking forward to your advice, benchmarks, and any insights that could help the community make the most out of the A20 boards!

A13 / A13-OlinuXino disagling debug ...
Last post by Davide - September 04, 2025, 02:49:36 PMHi!
I am trying to disable kernel messages over UART1 (ttyS0).
What I tried so far:
- removed env variables for 'console' and 'loglevel' and put on 'uEnv.txt' `console=tty1 loglevel=0`
- got rid off the `[uart_para]` section, the one with the debug settings, from 'script.bin'
- uncommented `kernel.printk = 3 4 1 3' from '/etc/sysctl.conf'
- tried to add 'boot.scr' with 'console' and 'loglevel' as above (before I wasn't using any 'boot.scr')
The output from '/proc/cmdline', `console=tty1 loglevel=0 root=/dev/mmcblk0p2 rootwait panic=10`, shows the correct values and I actually see printings on my display. However, messages are sent over ttyS0 too.
The image I am using is "A13_debian_34_90_WIFI_RALINK_GCC_GPIO_X_I2C_100KHz_UVC_TS_FTDI_3G_video_accell_release_10", taken from https://ftp.olimex.com/Allwinner_Images/A13-OLinuXino/2.legacy_images_kernel_3.4.x
Thanks to anyone who will answer!

A20 / Re: Old olinuxino a20 kernel i...
Last post by marcohani - September 03, 2025, 06:29:10 PMQuote from: luimarma on July 25, 2025, 08:16:46 PMI am trying to boot from SPI flash an old kernel image 3.4 series in an Olinuxino A20 board.
There use to be a file called migrate_to_SPI_eMMC_boot.txt, but I cannot find it anymore.
Anyone can point me to the right information?
Regards
Lu
Check the Olimex GitHub repo, specifically the A20 software section. The file might have been deprecated, but the SPI boot instructions are in the Linux-A20 repository.
