Hi, You aregetting this isseu while downloading the application on module(95% download and then error).Can you please try the following : 1. Close the post ,reset the module,open the post again and try to download. 2.Is the module properly detecting on dev studio in target management. 2. Di you try with some other module on same firmware version or on some higher version. 4.Also ,are you able to perform the same operation on dev studio 2.2.1 Thanks. ---

Application download finish properly, after that, make a lot of another readings, and finally when tries to start the application to debug it does no work. 1)i tried a lot of times, even reseting the module where the failure happends. it fails with usb/serial converter and with the USB port directly. so i would like to think is not the port communication, 1. yes, it reads everything they want from it and shows in the target manegement window. 2. unfortunately i only have this module for developing , until the first prodution prototypes comes. anyway if i download an application and start in production mode the module works properly. firmware version is not my choice, so it must work with this one. 1. i do not have previous versions of the dev studio to check. any idea about what are the last operations, need to configure something else? i try another time the next week. ---

There are identified issues with embedded GDB on FW 7.47.4 and 7.47.6, but FW 7.47.0 is working. Can you double check anyway which FW version you are running. Simple check also: are you running the Debug build configuration? As mentioned in the quoted post, Release configuration can’t be used for debugging. Anyway, DS should warn you if you’re trying to do this, but who knows… 😉 ---
