I recently have Armbian installed on my set-top box and its apt got crazy when I used it:

$ sudo apt install xfce4-terminal

The following additional packages will be installed:

The following NEW packages will be installed:

When following this guide on a host not capable of native arm64 KVM, replace -M virt -cpu host -accel kvm with -M virt,virtualization=on -cpu max.

The reason for virtualization=on is that the Windows bootloader does an smc #0 PSCI call, but without EL2, QEMU's TCG does not handle those because PSCI is in HVC mode and such that instruction is treated as undefined. With KVM enabled, smc #0 is handled properly.

Workaround in QEMU for using TCG without virtualization=on:

diff --git a/hw/arm/virt.c b/hw/arm/virt.c
index b871350856..de11ff51d1 100644

Mackie Thump GO Bluetooth Protocol

Connection

The Thump GO is visible as two Bluethooth devices. Thump GO is an audio device. The Bluetooth device named LE_Thump GO is used for controlling the loudspeaker.

Only after an audio connection was established and the bluetooth LED lights solidly, the LE_Thump GO device is active. (With Auto Connect off, connect from a previously paired audio device to reach that state. With Auto Connect on, this state is only reached 60 seconds after turning on, even if the audio connection is established much earlier, but one can presses the PAIR button to shorten that time.)

The Bluetooth device LE_Thump GO is the interface the official app Thump Connect 2 uses. This device offers service UUID 49535343-fe7d-4ae5-8fa9-9fafd205e455. Appearently, this is the BM70/RN4870 chip with service "Microchip Transparent UART". Here, I list all the commands of the device I could reverse-engineer. I assume no liability for the correctness.

Sudo command for cmd

What is this?

In Linux, we can use sudo to run command as root. In Windows, we can use runas command to do that, but it doesn't support for empty password file! So we make this small macro for you to do the same thing as sudo for Windows.

How to use this?

Install this macro:

doskey sudo=start /min powershell -Command "Start-Process $* -Verb runAs"
