Re: HP's thinking behind the 20b/30b? Message #4 Posted by Tim Wessman on 7 Sept 2013, 10:21 a.m., in response to message #1 by John Ioannidis
Cyrille basically. The thinking was:
1. It was hoped it could be a platform for re-purposing (embedded systems course in education for example).
2. Opens possibility for in field updates, or at various hp locations (this was a long shot. Unfortunately it could never happened to complexity of process and non standard cables/connection). Unable to do something like USB since that added significant cost - the exposed pads did not.
3. Allows a single HW version instead of special ones for development.
4. Ability to run automated testing on HW including production units.
And yes, any of the atmel chipped units have the ability to re-flash. The 20/30b is the only with the jtag though. Mainly it was removed because later it wasn't really needed at all for development since things were already running.
