I’m following the Getting Started instructions for the DashPro. The simple serial gateway exercise worked but I can’t get the Arduino to load the sample sketch. I get “An error occurred while uploading the sketch” without any other explanation from Arduino 1.6.12 using Hologram Board v0.9.1. I get the same error msg from an iMac Sierra and MacBook El Capitan. I thought I should upgrade the firmware and downloaded the updater and latest firmware bin. But the updater exits with an “illegal instruction 4” and does nothing on both Macs.
Any help would be appreciated. Thanks.
