I have recently purchased a new ardupilot mea board. Having soldered and connected it to the shield, I attempted to upload the firmware. However, I get the following error:
Failed to read firmware.hex: Index was outside the bounds of the array.
Any help on the issue would be greatly appreciated.
I assume you're loading from the Mission Planner. Did it download the firmware from the Internet correctly, and then start the upload to your board?
