I am trying to run the sample apps (NCP-locator-host-connectionless, NCP-target, Asset-tag-connectionless) provided by silabs. It builds successfully and the hex files are generated. First time when I flashed the respective codes in WSTK kit (BRD4001A) and asset tag(thunderboard), it was working properly. I have flashed the bootloader images too for both wstk and asset tag. After few days I tried testing the codes again but now it is just stuck on "Resetting NCP Target". I had updated the firmware to the latest version before second time testing. I am not able to figure out the problem. I have followed the same steps I did when I tested the code for the first time. It is not a hardware problem, because I tested in another kit and it is coming the same for it, also the hex files given for the demo code, when I flash it , it is working fine as well. I have attached the screenshots of first when I tested the codes and the current screenshot.
Thank you in Advance!
