Topic: rAPP updater
The recommend way of updating the ARM firmware is using the rAPP updater. This can either be run from "load target" and selecting the ini file, or renaming the ini file to "replay.ini" and powering on the board.
The flashing works fine, but at the end when you are asked to press "R" to reboot, sometimes the board will hang.
Don't panic, just power cycle it.
I'm looking at this.
