  • Hi Fabian, We have tested your example, it works great and I think we have found the problem. After looking more in our production software, we find out the production software sets the first telnet port to 19022; "-rtttelnetport 19022". We think this telnetport is linked to "JLinkGUIServer.exe". We have now set the telnet port in our production software to 1234, and it works perfect. I only have questions about the log, cause the log shows "TELNET listener socket opened on port 19022" when the …

  • Hi Fabian, No, unfortunately the "exit" at the end does not fix the issue. Kind regards, Karel

  • Hi Fabian, The issue occurs when flashing the PIC32 with JLink, PIC32 flash with jflash is not possible with the current version, V6.80d. the situation is: MCU1 = EFR32FG14PxxxF256 MCU2 = PIC32MX440F128L We do the following steps: 1) JFlash to flash firmware MCU1 2) JLink to flash firmware MCU2 3) Jlink connect to MCU1 4) Link to telnet "localhost:1234" We think the problem is the combination, flashing MCU2 with Jlink and after succesful flash, directly communicate with MCU1. 1) JFlash to flash …

  • Hi Fabian, We connect to telnet by first connecting the device with Jlink, using the following command: Source Code (1 line) when connected to jlink, we can setup a telnet communication to the address: localhost:19021. this works most of the time, it only doesn't work when “JLinkGUIServer.exe” is active. We setup the jlink communication directly after the PIC32 firmware flash. If we put a 10 seconds delay between the PIC32 firmware flash and the jlink communication with the EFR32, “JLinkGUIServe…

  • Hello everyone, I cannot connect with Segger's RTT to my device directly after flashing another device, using the same jlink adapter. I hope somebody can help me with this. We are creating a production tool to flash and test a product with 2 microcontrollers, using 1 Segger JLink base. The targets are: - EFR32FG14PxxxF256, Silicon Labs - PIC32MX440F128L, Microchip The production programmer performs the following steps Step 1:Flash the EFR32, we are using J-flash with SWD communication. Step 2:Fl…
