Hi NXP,
Full Context for ur understanding. We are using NXP s32k144 for our project. We are writing a code for PBLupdater which will erase and write present PBl with a new PBL. At first, both PBL and PBLUpdater were in FLASH. Then we were facing MEMManage fault , we understood that as both PBL and PBLUpdater were in the same read partition block --that caused the fault. So we are trying to execute the PBLUpdater functions to erase and write to flash in FlexRam.
---SORRY FOR MY SYNTAX----
Our Function definition look like this:
__attribute__(section(".FlexRamSection")) EraseSectorFucntion definition(address){.....}
__attribute__(section(".FlexRamSection")) EraseSectorFucntion definition(address){.....}
Linker file look like this:-
define region FlexRam=mem:[from 0x14000000 to 0x14000FFF];
place in FlexRam
{ ro section .sectionName};
In our Code we call the function like this:
int main(){
...
...
EraseSectorFucntion();
....
}
using as a pointer also we tried:
int main(){
...
...
funcpointer=&EraseSectorFucntion();
funcpointer();
....
}
i'm sure that the function is at the FlexRam Address(looked in Disassembly). but when i execute the code. i'm getting Hard Fault for Undefined intruction. Please provide some idea/hints.
