BOOT to APP jump issue

[pankajprasad100]

Hi,

I am working on a bootloader in which all the steps are done but while jumping from boot to app there is an issue.

I followed this link-Boot to Application Jump in S32K116? - NXP Community

In the above link there is an word attachment. While using the given function in our code which is provided in the document getting error as "Operand syntax error"

Hi,

I can see that it can't recognize "sp". That's because there are two stack pointers - main stack pointer and process stack pointer. From ARM Cortex manual:

And example from application note AN12218:
