Overview
This application note covers, in detail, the steps required to program an Octoclock or Octoclock-G to allow Ethernet connectivity and communication with UHD. This guide serves as a supplement to the UHD Manual's coverage of the topic. In this guide, we will use Ubuntu 19.10 to program an Octoclock using an ATMEL-ICE programmer.
Verify Current Octoclock Configuration
To get started, we want to make sure that this guide is appropriate for your device(s). Currently shipping Octoclocks will come with the following firmware pre-loaded. You can test which unit you have with a simple ping test:
- Connect the 6V DC power supply to the Octoclock
- Connect your Octoclock's RJ-45 port to a host PC via an Ethernet cable
- Configure your host's Ethernet port to a static connection with the IPV4 address:
192.168.10.1 - Configure your host's Ethernet port with a subnet mast of:
255.255.255.0 - Turn your host's Ethernet port off and back on for changes to take effect
- In a terminal, issue the command:
ping 192.168.10.3
A successful ping between devices means that your device is already configured with updated firmware and this guide is *not* necessary. At this time, this guide has not been tested for recovering bricked devices.
Tools Required
- Philips head screwdriver
- ATMEL-ICE Programmer (or comparable AVR programmer) with SPI/ISP cable
- Ethernet cable
ATMEL-ICE Configuration
To utilize the ATMEL-ICE programmer, the avrdude utility must be used. The version of avrdude should be >= 6.1. At the time of this guide, version 6.3 is the default install from the Ubunu PPA and programming issues were observed. This guide will cover a build of avrdude 6.1 from source.
Install the following dependencies:
sudo apt-get install bison flex libftdi1-dev libftdi-dev
Download the avrdude-6.1.tar.gz release here. From this download location, uncompress the directory:
tar xvzf avrdude-6.1.tar.gz
Enter the source directory
cd avrdude-6.1/
Run the configure script
./configure
Expected output:
<truncated output> Configuration summary: ---------------------- DO HAVE libelf DO HAVE libusb DO HAVE libusb_1_0 DO HAVE libftdi1 DO HAVE libftdi (but prefer to use libftdi1) DON'T HAVE libhid DO HAVE pthread DISABLED doc ENABLED parport DISABLED linuxgpio
Build
make
Install
sudo make install
Test your avrdude installation
avrdude -?
Expected output
<truncated output> avrdude version 6.1, URL: <http://savannah.nongnu.org/projects/avrdude/>
Download Octoclock Firmware
If UHD is not already installed, install your preferred version with this guide: Building and Installing the USRP Open-Source Toolchain (UHD and GNU Radio) on Linux
Download images for UHD:
sudo uhd_images_downloader
Verify that you have octoclock_bootloader.hex and octoclock_r4_fw.hex
ls -l /usr/local/share/uhd/images | grep octoclock
Expected output
-rw-r--r-- 1 root root 17332 Jun 6 2019 octoclock_bootloader.hex -rw-r--r-- 1 root root 22845 Jun 6 2019 octoclock_r4_fw.hex
Change to this directory:
cd /usr/local/share/uhd/images
Connect Programmer to Octoclock
Begin this guide with the Octoclock unplugged. First, you'll need to remove the top plate from the Octoclock, exposing the PCB. There are 12 screws securing the top plate.
With the top plate removed, locate the 6-pin header (J108, male) for SPI communication with the ATmega128.
Connect the ATMEL-ICE's 6-pin header (female) to the SPI header of the Octoclock as shown below. The tab of the header should be facing the ATmega128 chip.
Note: If you plug the header in backwards, avrdude is expected to return a "please check your connections" message after a programming failure. See the section "Troubleshooting" at the bottom of this document.
If not already done, connect the other end of the SPI cable to the ATMEL-ICE's AVR squid connector, and connect the ATMEL-ICE to the host computer using the micro-usb port. There should be a single LED lit on the programmer.
Supply power to the Octoclock with the 6V power brick. You should see the Octoclock's Power LED come on and 1 additional green LED on the ATMEL-ICE programmer illuminate.
Program the Octoclock
With the terminal that is open in the same directory as the .hex images, run the following command
sudo avrdude -p atmega128 -c atmelice_isp -P usb -U efuse:w:0xFF:m -U hfuse:w:0x80:m -U lfuse:w:0xEF:m -U flash:w:octoclock_bootloader.hex:i
If you are using a programmer other than the ATMEL-ICE, you will need to change the -c parameter to match your programmer. Valid programmers for your version of avrdude can be found by running:
avrdude -c help
The expected output from a successful run of avrdude is as follows:
avrdude: AVR device initialized and ready to accept instructions

avrdude done. Thank you.
Uploading Firmware via Ethernet
Upon successful burning of a bootloader, you will now need to upload firmware. Connect the USRP to your host via Ethernet and configure your host's IP as noted in the "Verify Current Octoclock Configuration" section. Next, run
uhd_find_devices
Expected output:
uhd_find_Devices
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
addr: 192.168.10.3
type: octoclock-bootloader
This means that UHD successfully recognizes your device's bootloader and can download the firmware image. Run the following command:
uhd_image_loader --args="type=octoclock,addr=192.168.10.3"
Once this completes, your OctoClock will load its firmware. Powercycle the device, then run the uhd_find_devices utility again, and the output should be similar to the following:
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
addr: 192.168.10.3
type: octoclock
name:
serial:
Note that the Octoclock will enter its bootloader once it first receives power. It will take ~10s to boot and be recognized as an octoclock as seen in the above output.
Updating the Octoclock's EEPROM
As a final step, the device's EEPROM will need to be updated. On the back of your device, you will see a label sticker with a serial number (labeled S/N) and a MAC address (labeled MAC). For later use, the MAC address will have to be used in a different format than is on the label. As an example, if the label lists the MAC address as 00802F112233, you will need to format it as 00:80:2F:11:22:33.
Update the Octoclock's EEPROM witht he following command:
<UHD INSTALL DIRECTORY>/lib/uhd/utils/octoclock_burn_eeprom --args="addr=192.168.10.3" --values="mac-addr=<FORMATTED MAC HERE>,ip-addr=192.168.10.3,netmask=255.255.255.0,gateway=192.168.10.1,serial=<SERIAL HERE>,revision=4"

Troubleshooting
This process has been run and confirmed in Ubuntu 19.10. Other versions of Linux may require different versions of dependencies to be installed.
You can use -v flags with avrdude to make the output verbose, if running into issues. Here is the ouput of avrdude with verbose flags set:
sudo avrdude -v -v -p atmega128 -c atmelice_isp -P usb -U efuse:w:0xFF:m -U hfuse:w:0x80:m -U lfuse:w:0xEF:m -U flash:w:octoclock_bootloader.hex:i
Output when SPI plug is plugged into the header backwards:
