    • Issue using JLinkGDBServerCL.exe with EFR32xG24 since Version V7.94

      I am encountering a problem with JLinkGDBServerCL.exe when using an EFR32xG24 chip with JLink software versions after V7.92q. As shown in the terminal output below, V7.94 gets stuck during the “Comparing Flash” step for 2+ minutes and then displays the error message “Timeout while calculating CRC, RAMCode did not respond in time!”. I am able to debug normally after this happens.

      Again, The issue does not occur with V7.92q, only subsequent versions. As shown in the image from the JLink Change log I have attached, V7.94 had specific updates for this chip - perhaps a new problem was introduced?

      Note that I have replaced the specifc chip I am using with EFR32xG24 in the command line example for this post!

      After this, it tries again and works fine.
