after programming the nrf51822 the SWDIO/nRESET pin is in "debug mode", to resume the normal mode the SWDCLK and SWDIO/nRESET line shuold low for a minimum of 100 μs (nRF51 Series Reference Manual). But with this procedure, I can not get into the normal mode.
If i do a pinreset from the debugger (cmd line: "nrfjprog --pinreset") and look at SWDIO/nRESET line with an oscilloscope, an entire sequence of resets is triggered.
What I have to do, to go back in the normal mode, if i don't want to do a power cycle?
Please reply :-) Waiting for response...
You can have a look at this :
A physical pin reset is still needed.
