KV58 ZI段满了怎么办啊 不会改icf

笔记本发烧友

cannot fit "Block ZI"


现在我的icf是


define symbol __ram_vector_table_size__ =  isdefinedsymbol(__ram_vector_table__) ? 0x00000400 : 0;

define region DATA_region = mem:[from m_data_start to m_data_end]
                          | mem:[from m_data_2_start to m_data_2_end-__size_cstack__];
这个里面，把data 3 也放进去试试。
define region DATA_region = mem:[from m_data_start to m_data_end]
                          | mem:[from m_data_2_start to m_data_2_end-__size_cstack__]
                           mem:[from m_data_3_start to m_data_3_end];
