How to update the firmware

This howto explains how to update the firmware running on your rad1o from a binary release.

The rad1o firmware consists of these main parts:

• The bootloader
• Applications (camp, hackrf, testapp, …)
• l0dables (snake, schedule, …)
• Other files (configuration, fonts, graphics)

See firmware:releases for the most recent version and a release history.

Alternatively, you can build the firmware yourself and flash the latest version from git

• A rad1o
• A computer with a USB-Port
• A micro USB cable
• A firmware file

• turn off the rad1o
• connect the rad1o (rad1o port A) with a micro-USB cable to the computer
• push and hold the joystick UP while you turn on the rad1o. it will now boot in MSC mode, appearing as a mass storage device (like a USB stick) to the computer
• Download the latest firmware file
• unpack it and copy all the contained files to the mounted device, overwriting the existing files

cd /mnt/FE49-AB84
tar -xzv --strip 1 -f ~/Downloads/rad1o-revXX.tgz
sync

(The paths will probably be different on your system; For example, the mount point in Debian/Ubuntu/Mint may be in /media/[username]/[device name; e.g. 0FC0-CABC])

(The tar has the firmware files in a subdir, hence the –strip 1 [at least rad1o-rev02.tgz does]; the new firmware files must go to the root of rad1o's file system, or the upgrade won't work.)

(OS X users: If you unpack and copy via the Finder a lot of resource fork files will be generated, so tar is preferred.)

• wait until the left bottom LED stops flashing
• unmount the device
• turn your rad1o off and on again. (If your screen goes dark, try unplugging the USB or setting the chargeled config to 0.)

Your rad1o should now run the most recently released firmware. You can check the release version of your firmware in the “INFO” menu.
