OS

What OS is ROCK Pi E running?

Currently we have Debian Buster, Ubuntu Bionic, etc, running on ROCK Pi E.

Can I ssh to ROCK Pi E running official Debian/Ubuntu?

Yes, you can. The ROCK Pi E is shown as rockpie.local in your local network. Check out the Using SSH page.

Where is the Radxa APT sources list?

Check file /etc/apt/sources.list.d/apt-radxa-com.list.

Some BT devices are discovered, but failed to connect to them on ROCK Pi E?

One of the reason is the weak signal. To gain a stronger signal, you need an antenna attached to the antenna socket on board.

Radxa APT public key is not available

When I try to run apt update, i get following error:

$ sudo apt update
...
Err:21 http://apt.radxa.com/bionic-stable bionic InRelease

The reason is the public key used before is expired. You can execute the following command to get the new available.

sudo apt-get install -y wget
export DISTRO=buster-stable
wget -O - apt.radxa.com/$DISTRO/public.key | sudo apt-key add -
sudo apt-get update

How to backup the debian image

1. Download the script and put into some directory of the board system

   https://github.com/akgnah/rockpi-toolkit/blob/master/rockpi-backup.sh

2. enter the directory and run

   sudo ./rockpi-backup.sh -m rk356x

Note:

if you encounter errors like not found kpartx, mkfs.xx, resize-helper, you need download from the pc and copy to the board system

kpartx

mkfs.xxx

http://ftp.cn.debian.org/debian/pool/main/d/dosfstools/dosfstools_4.2-1_arm64.deb

resize-helper

git clone https://github.com/96boards/96boards-tools.git and get the resize-helper and cp   resize-helper  to /sbin (board system)
