thanks for the information. I'm quite sure that I have seen some web
pages that use the FlySwatter2 together with a BBB. But If you had some
bad experience, I'll not recommend the FlySwatter2 or some OpenOCD based
debugger for the BBB in the next time.
As a positive report: I have a quite stable setup with the Segger J-Link
EDU. The EDU is a affordable variant with the disadvantage that it must
only be used for non-commericial purpose.
