    The head revision FW does not work with my rad1o badge

list of open questions


does the new FW utilize some HW-Components which may be broken (from the beginning) but never used by the old FW?

if yes: which components are in question? https://github.com/rad1o/hardware/blob/master/rad1o.pdf

wild guess: the arm mcu -> bga contact problem?! Is this testable via software, jtag or testpoints on the board?
