code execution problem in SRAM

youngseolee — Wed, 21 Dec 2016 07:59:50 GMT

i try to execute code in SRAM using a function pointer.

My project is implemented as follows:

1. my project is implement as INTERNAL_FLASH mode, and 'function_A' in my project is relocated to a specific address (0x40010000) in SRAM

2. Declare a function pointer that point specifies the specific memory address (0x40010000), and execute it.

When I run my program, my program call 4000 command, then It falls into exception handling handler.

but, My program works fine at a specific memory address (0x40010000) when the program call a 'function_A' normally.

I want to know why this problem is occurred.
