Hi,
I'm using the STM32F103ZE uC developping in C and asked to implement a full internal ram memory test. The memory runs from address 0x2000 0000 up to 0x2000 FFFF.
When main() is started allready the stackpointer and data are initialized so some memory locations are occupied.
Just my thoughts: I could create some assembler function that checks/writes/reads the non occupied free memory, then copy the occupied memory to the allready tested free memory, then test the occupied memory, then restore the occupied memory from the free memory.
Is there some other way to test the memory before the uC initializes the memory?
Thanks
Henk
