I have ported the Kinetis_Bootloader for KL16 from KL26，it works well. Then I used the bootloader GUI to download user application，after program successed，the user application works normally too.
But，if I shutdown the power and then repower，user application dosn't work。I used a LED to Indicate the bootloader program，so I'm pretty sure that the bootloader is working correctly。
why is the user appll can work only once? If anyone else meet the problem?
