Upgrading your Re:load Pro firmware
Some of you have started receiving your Re:load Pros already! Since the firmware is evolving rapidly, the firmware on the device you received is already not the latest version. Later updates make several improvements, including adding support for undervoltage cutoff, and improved calibration routines.
pip install cyflash
Once cyflash is installed, plug your Re:load Pro into your computer and identify what device it shows up as. On linux and mac, it will show up as something like /dev/tty.usbserial-somenumbers. On Windows, it will show up as a COM port, which you can identify using Device Manager.
Next, you need to put your Re:load Pro into upgrade mode. Press the encoder button to enter the menu, then scroll down until you see "Upgrade Mode". Highlight that and press the encoder button again.
Now that you have the firmware and know how your Re:load Pro has identified itself to your OS, you can issue the update command:
cyflash --serial device "Reload Pro v1.4.cyacd"
Replace 'device' with the name of your USB device, and the filename with the filename of the latest firmware version.
Cyflash will then upload the latest firmware, and your Re:load Pro will reboot. It should show the new firmware version number on the boot screen. Congratulations!
