How to allocate program memory and storage before running my application in Wince?

Question

I am reprogramming a C# application to run on Windows CE, but my machine has little memory.
Therefore, I need to allocate the appropriate amount of processing memory (program memory) and storage memory (Storage memory). I can’t manually allocate this to each reboot, so I found the function Setsystemmemorydivision().
The code to allocate memory is basically the following:

        //Confere se a memória está alocada corretamente
        while (storage_page != 800)
        {
            //Seta a memória para 800 pages de 4096 bytes cada (4Kb * 800 = 3.200Kb)
            storage_page = 800;

            //Grava a memória setada
            SetSystemMemoryDivision(storage_page);

            Thread.Sleep(200);

            //Lê a memória do sistema
            GetSystemMemoryDivision(ref storage_page, ref ram_page, ref page_size);
        }
        chamamenu();

The function is working in debug mode, but whenever I restart the machine and try to run the program, the system crashes.

How can I ensure that the memory has been allocated before running any other process that might lock the machine? It is possible that the application is allocating more than the 32mb available for RAM.

Problem solved.

The main problem was with the GC of CF 2.0, which was not managing the collection correctly.
With an update from . NET CF v2.0 for v3.5 both on machine and project, GC started to properly manage the collection and the application worked perfectly.

Thank you to everyone who tried to help and hope that I helped someone with similar problems.

I don’t know much about Windows CE, but if you need more memory, use virtual memory. http://msdn.microsoft.com/en-us/library/dd997372%28v=vs.110%29.aspx

If using . NET ready imports does not work, use P/Invoke. http://www.codeproject.com/Tips/79069/How-to-use-a-memory-mapped-file-with-Csharp-in-Win
