running Windows 10 Pro 22H2 and using j-link v9
i tried to read firmware from nrf51822-QFAB by using "nrfjprog --readcode dump_nRF51822.hex", but it gave me an error -102:
C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin>nrfjprog.exe -r
[error] [ Client] - Encountered error -102: Command connect_to_emu_with_snr executed for 187 milliseconds with result -102
ERROR: Unable to connect to a debugger.
[error] [ Worker] - An unknown error.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.
All drivers installed
Running latest version of nRF command-tools 10.24.2 for Windows x64
j-link is connected to SWCLK and SWDIO pins correctly
nRF51822-QFAB uses external power and microcontroller itself works correctly
here is the log.log file for better information:
