nrf-command-line-tools: connect to multiple j-link's devices in parallel

[Adrian Luk]

Hi dear, 

It is possible to establish parallels multi connection to different J-LINK's devices serial numbers via nrfjprog.dll, or any other automated way ?

We successfully establish connection (read and write) between one (1) J-LINK device and one (1) PCB device via NRFJPROG using "nRF Command Line Tools" version 10.16.0 on C# .NET application. 

While trying to have a concurrent connection to another J-LINK Device SN and PCB, we receive error type : INVALID_OPERATION = -2

Method used: NRFJPROG_connect_to_emu_with_snr

Please advice

BR,

Adrian

Hey .I have changed Msgcallback  accordingly. I also changed the first parameter to void* C# equivalent (IntPtr)

IntPtr handle = IntPtr.Zero;
            var openDllReturnValue =
                NativeMethods.NRFJPROG_open_dll_inst(                     
                    ref handle,
                    JLinkPath,
                    Marshal.GetFunctionPointerForDelegate(new MsgCallback(OnMsgCallback)),
                    Device_family_t.NRF52_FAMILY);

Still same result. The log is:

open
Jlinkarm nRF Worker ready. Handling sequence 0a24bcf2-8825-45ce-9800-3cc3bdff36f5.

Hi Adrian,

I'll be taking over this case from Stian. Were you able to find a solution for your issue?
