Getting Started

Installation OS

for Raspberry Pi CM4

1. Download an image from here https://www.raspberrypi.com/software/operating-systems/

2. Clone usbboot and compile it

   sudo apt install git libusb-1.0-0-dev pkg-config
   git clone --depth=1 https://github.com/raspberrypi/usbboot
   cd usbboot
   make

3. Hold down the maskrom key, connect the computer using the A-A cable, and release the maskrom key

4. Run rpiboot and view the CM4 device

   sudo ./rpiboot
   lsblk    # assume that CM4 is /dev/sdx

5. Burn the image to CM4

  xz -d /path/to/yymmdd-raspios-bullseye-xx.img.xz
  sudo dd if=/path/to/yymmdd-raspios-bullseye-xx.img of=/dev/sdx status=progress 


for Radxa CM3
 * TBD

Software support

Taco-fan.png

We have provided a script to help control the Taco fan.

curl -sL https://rock.sh/get-taco | sudo -E bash -

Just copy the command above and paste it into the terminal and press enter.

Power Options

Power Consumption
SSD <3W
2.5 HDD 3 ~ 5W
3.5 HDD 5 ~10W
Option 1: Power from DC (5.5*2.5)

We provide a 12V/5A DC power supply, which is included with the Taco kit.

Option 2: Power from ATX PSU

If you plan to put the Taco in a PC enclosure, then you can use the ATX PSU. Mostly ATX PSU can meet the power requirement. You need an ATX Floppy cable to power the Taco.

Known Issues

  • Booting from M.2 NVMe SSD is not supported since there is no driver for the PCIe switch on the Taco in the Raspberry Pi bootloader.
