DAP error while trying to run debugger

[YCH]

Hi!

I am currently working with the nRF51 Development Kit board (PCA10028). while trying out some of the samples (mainly - gzll dynamic paitring host and gzll dynamic paitring device) i have started to get error messages when trying to run the debugger:

Error Message

i've tried the advice on this thread: devzone.nordicsemi.com/.../ with no success, as can be seen in following screenshot:

CommandLine errors

i also would like to mention i had made some writes to the flash memory in these addresses (0x000009400), (0x000009800), (0x000009C00), (0x00000A000) - starters of pages in the flash. maybe it had something to do with this?

Please advise on how to solve this issue and what was the cause?

thanks alot :)

Hi, Found the problem. was writing to the flash in very short intervals and as a result something got messed up with the addresses.
