We just acquired a mdc2230 controller who was actually in the firmware v15
we try to pass it in v14a by download it in DFU mode and that works but
now we can't communicate anymore with it in USB and in RS232 mode it blocks
after telling us "starting...".
On power on, The "stat" LED blinks fastly during one second and become continue. The pwr led stays on.
Is there a way to put it again in DFU mode or factory default mode ? Is there a jumper inside the PCB to force the dfu mode ?
