Best practices to optimize A20 performance on Linux

[jeffreestar]

Hello 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!

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:
