Thank you for your reply I tried the "Authorized flashing" with my J-link. I followed the "Moving files to the secure area" of the UM08022. it worked for me Thanks
Dear All, I know that once i set up the flasher, anyone can download the data from flasher to target. but i want to know that someone could read the data(hex file of a Firmware) from the flasher which i set up before because I have to protect my data. Thanks
