Contains firmware versions: v1.09p3 and v1.10p4

The OS X version of the ER-101 Programmer is under development and planned for release soon. 
Until then I invite you to use this very simple command-line tool to update the firmware on your ER-101.

Installation
  • Download the ZIP file from the link above and unzip it in a location of your choice (e.g. ~/Downloads).
  • Please find a file called README which contains detailed instructions on how to upgrade your ER-101's firmware:
Welcome to the firmware upgrade tool for the ER-101.

WARNING! Flashing firmware to the ER-101 this way will erase your snapshots.

Instructions:
1. Take your ER-101 out of the case and disconnect the power cable.
2. Make sure the +5V source is set to REG or BUS.
3. Connect your ER-101 via USB to your computer.
4. While holding down the RESET button, switch the +5V source to USB.
5. If nothing lights up on the ER-101 interface, then the ER-101 is ready for firmware upgrade.
6. In a Terminal window, 'cd' to the directory where you unzipped the firmware upgrade tool, like this:

cd ~/Downloads/er-101-firmware-tool-for-osx

7. Choose the firmware version and execute the upload script for that version,

./upload-vXXX-to-device.sh

8. You should see the following output:

Erasing flash...

Good Luck!
