IAR编译器的.ICF文件，如何扩展NXP的RAM。


        Error[Lp011]: section placement failed                       



                    unable to allocate space for sections/blocks with a total estimated minimum size of 0xf40a bytes (max align 0x4) in <[0x2000'0000-0x2000'ebff]> (total uncommitted space 0xec00).                       

如下是 .ICf文件内容

还有额外的RAM空间可以使用吗，如果有的话设置下即可，比如我这里扩展了个SDRAM

应该是我表述有问题。
我程序了定义了一块大内存。编译发现RAM不够了。
昨天晚上解决了。
define symbol m_data_start             = m_interrupts_ram_start + __ram_vector_table_size__;
define symbol m_data_end               = 0x1FFFFFFF - v_REGION2_ADD;

/* SRAM_U */
define symbol m_data_2_start           = 0x20000000 - v_REGION2_ADD;
define symbol m_data_2_end             = 0x2000EFFF;
将REGION2区域  扩大即可。
place in DATA_region_2                      { first block customSectionBlock };
这个区域存放用户自定义数据。
