Title: Firefly RK3288 USB Keyboard Problem
Hi,

I have bought my board from Aliexpress. I have started to use both android and ubuntu images from both NAND and SDCard. In all the versions, I have a repeating keyboard key problem. I have tried different types of keyboards (wired and wireless usb keyboards). All have the same problem.

I searched the forum and other internet resources and could not find an acceptable solution.

Can you please identify the solution as soon as possible?

Thanks in advance...

Doruk

It is a known problem.
I did see in the Firefly KitKat source on Bitbucket there was lots of USB fixes in November.
But there is no new firmware for anyone to test right now.

It is really weird that a sbc has a general usb keyboard problem. I wonder how people work on the system without a keyboard.

In the system settings of both Android and Ubuntu, check if there are keyboard related options. Sometimes there are options or updates to fix this problem.

Hi Doruk,

It sounds like a frustrating issue! The repeating key problem could be related to the keyboard settings or drivers, especially if both Android and Ubuntu are showing the same behavior. Have you tried adjusting the keyboard repeat rate or checking the keymap configuration on both systems? Sometimes, a simple update or different kernel version could resolve the issue. Also, make sure the USB ports or hubs aren't causing any issues. If the problem persists, checking for any firmware updates for your board might help as well. Hopefully, one of these solutions works for you!

Good luck!

Keyboard issues like repeating keys can often relate to software compatibility or power supply variations, especially on boards sourced from platforms like AliExpress. For CRM and ERP consulting tasks involving device setups, troubleshooting is key. Here are some steps that might help:

1. Check Power Supply: Ensure your board's power supply is stable, as insufficient power can affect USB devices.
2. Test Driver Updates: Check for keyboard driver updates in both Android and Ubuntu settings.
3. Input Delay Settings: In Ubuntu, adjust "Keyboard Repeat Rate" and "Delay" under Keyboard settings.
If the issue persists, consider testing another SD card or seeking a firmware update, as some boards may have compatibility issues with specific peripherals.
