I have a question when I am trying to implement bootloader of S32K118, please give me some help.
First of all, I have defined the ".noinit" section in the linker file ,from 0x200057C0 to 0x200057FF.
Then, I have defined two pointer variables(uint32_t) like this:
uint32_t * pProgrammingReqFlag = (uint32_t *)0x200057c0;
uint32_t * pApplicationValidity = (uint32_t *)0x200057c4;
And the values in these addresses will be checked after reset(you will find in "main.png").
The question is: when I downloaded this project into hardware ,it works well, but if I reset the hardware (power off and power on), it do not work any more !
How to access the .noinit section ? or is there anything else need to be modified in the linker file?
BTW, if these two variables point to any other address which is not located into the .noinit section, it works well after power on.
uint32_t * pProgrammingReqFlag = (uint32_t *)0x200027c0;
uint32_t * pApplicationValidity = (uint32_t *)0x200027c4;
