Forum Post: RE: TIRTOS Heap Problem

Hi Steve,

I attached three projects in zip files. The first one "M3_1.rar" is the working code with the heap size 20480. The second one "M3_2.rar" is the project which I changed the heap size to 40960 and this one can not be built as shown in figure 1. Yesterday, I found out  the reason why I got the error shown in figure 2. That is because I incresed the size of C02SRAM in the linker file (TMDXDOCKH52C1, can also been seen from figure 2). The original size is below.

MEMORY
{
    BOOTROM (RX)    : origin = 0x0,        length = 0x10000
    FLASH_BOOT (RWX): origin = 0x200030,   length = 0x4
    FLASH (RWX)     : origin = 0x200034,   length = 0x7FF9C
    C03SRAM (RWX)   : origin = 0x20000000, length = 0x08000
    S07SHRAM (RWX)  : origin = 0x20008000, length = 0x10000
    CTOMMSGRAM (R)  : origin = 0x2007F000, length = 0x800
    MTOCMSGRAM (RW) : origin = 0x2007F800, length = 0x800
}

I am just wondering now if that is possible to increase the heap size to 40960 or not ?

Thanks,

Ben
