S32K118 How to correctly jump from Bootloader to App with S32K Design Studio

[melvinw]

I'm creating my first bootloader with the S32K118 processor and i can't seem to correctly jump to my application.

What I'm trying to do is first flash my application on the MCU with a debug configuration. After that i flash my bootloader without erasing the application. When running my bootloader runs without problems but, when it tries to jump to the application i opens a new tab in IDE and stops the debugger at a breakpoint at address 0x346c. Which if I'm looking at the .map file of my application is my reset handler? But i doesn't execute any code. When it runs without debugger it seems to hang at the same point without executing the application.

Questions i have:

1. Am i missing something and is my code correct?
2. Are the settings, linker files, correct to jump to the application or do i need a different address?
3. How do you correctly jump to the application? 
4. What steps need to be taken? (Maybe I'm forgetting something.)

Thanks for any help in advance!

What I'm using:

• S32K Design Studio 
• S32K118 SDK RTM 4.0.1 with two seperate hello world example project for a blinking LED.
• Costume PCB with S32K118 MCU
• Multilink Universal debugger/programmer with a SWD connection to the MCU.
