1,I use nrfgo studio and can download softdevice ,it is OK.
2,I use the s110 example,it runs ok too.
3,I modify something from the example ,and click debug(keil),but it just earse the chip,and download the xxx.hex file,and it stop debug automaticly,
after that,
My jlink could not connect to the target chip.
I have done this (but didn't work):
1.use Jlink Commander,and enter command :r
it give the message:
Reset delay :0 ms
Reset type UNKNOW: ???
2.run cmd and enter command : nrfjprog --recover
it give the message :
Cannot connect to the nRF51 device
so,Is my chip (51822) damage?(seems likely "Locked"). I'm sure that the hardware is ok,and the connect line to the jlink is correctely! Is there some ways to recover ?
