![]() The top of the linker files say "Set heap size, stack size and stack location according to application requirements.Is it possible to merge SRAM1 & SRAM3 into one RAM block while leaving SRAM2 off limits? Would this help in any way?.How do I allocate a fixed amount of memory to stack and heap?.Whether originalClaim and workingClaim were stored on the stack or heap is irrelevant to your story. How can I customize my linker files so that I have globals at the bottom, the stack at the top, and the heap at the top right below the stack? As others have stated, value types have the distinction of being able to be stored on the stack, but that is where the relationship ends.Contrast these with stack and heap data structures. For example, the call stack can hold data pertaining to function calls and the heap is a region of memory specifically used for dynamically allocating space. The Stack is the temporary memory where variables are stored while a. 'The stack' and 'the heap' are memory lumps used in a specific way by a program or operating system. I wonder if SRAM2 is the culprit is some way. There are many long explanations of heap vs. MAP file denotes that memory is being allocated in SRAM1 and some of SRAM2. Maybe this isn't an issue, but it could be and it bothers me. My linker files are defaulted to treat all 3 segments as one block of RAM, which I don't like because the hardware of each is different. I really don't like the idea of using SRAM2 because it supports read & write protection and is just different from SRAM1 & SRAM3. The default linker & map files are attached. This MCU has 640KB of SRAM, but they are divided into 3 sections: It is clear that some manual work is required of me to allocate memory properly. I have much more code to add and so it is time to get to the bottom of this. I am now at level -03 and the bug is back. Difference between Stack and Heap Memory in Java: The JVM splits the memory into two sections: stack memory and heap memory. 'The heap' can be thought of as a catch-all for. heap allocation Go values whose memory cannot be allocated this way, because the Go compiler cannot determine its lifetime, are said to escape to the heap. As of late, I have been able to keep kicking the can down the road by gradually increasing the compiler optimization level at times when the bug comes back due to me adding additional code throughout my program. Typically, we refer to allocating memory for Go values this way as 'stack allocation,' because the space is stored on the goroutine stack. In summary, it has taken me a while to confirm that this is a memory management issue. For several months now, I have been fighting a memory based bug described in great detail here: ![]() You can write an entire program without using the heap. The heap is for objects that need to be accessed from multiple threads or throughout the program lifecycle. I am programming a FreeRTOS and CubeMx based application on the STM32L4S9AII6 MCU. Stack memory allocation (function variables, local variables) can be problematic when your stack is too 'deep' and you overflow the memory available to stack allocations.
