Tips and experiences with A13 board (Cortex-A8, 1GHz, 512MB RAM)

[michaelarrington]

Hello 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

• 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?

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.

The most stable images are the ones we provide. Olimage and older kernel sunxi images. Refer to the Linux guide here, it explains the Linux options in detail:
