编译时提示警告如下：
Description Resource Path Location Type
#10281-D Section ".testSect" requires a STATIC_BASE relative relocation, but is located at 0x0c280000, which is probably out of range of the STATIC_BASE. STATIC_BASE is located at 0x00810000.

想请问一下，第一条警告是什么意思？
Nancy Wang：
请问这个STATIC_BASE是定义的地址范围吗？或者您将cmd文件贴出来看一下。
,
Duan Siyu：
,
Nancy Wang：
没看到STATIC_BASE的定义。
从报错提示来看请在cmd中将 .testSect 段指定到 STATIC_BASE。
SECTIONS
{
.testSect > STATIC_BASE
,
Duan Siyu：
感谢，其实我更想知道后续几条警告的含义是什么，能帮助解答一下吗
,
Nancy Wang：
Duan Siyu 说：relocation from function "algProcess" to symbol "gCrc32" overflowed;
请贴出提到的这些名称相关代码的细节看一下。
,
Duan Siyu：
,
Nancy Wang：
没有看到 algProcess. 这两者的关系是什么？没有看明白。
,
Duan Siyu：
不好意思，是函数名称
void algProc(void){ if(ISMDSP) { if(0 == DNUM) /* core 0 initialize peripheral and record device state, then send PIC and execute SIFT*/ { int ret = 0, pos = 0, i = 0;
gSrioInfo.m_initRet = Drv_SIRO_Init(Dev_SRIO, DSP_PORT0_DeviceID, ((SRIO_PATH_MODE_2xLaneAB_2xLaneCD << 8) | Srio_LoopBackDisable), SRIOBPS_5000M);
gCanInfo.m_initRet = Drv_DPRAM_Init(Dev_DPRAM);
gNandInfo.m_initRet = Drv_NandFlash_Init(Dev_DPRAM);
if(0 == gNandInfo.m_initRet) /* if NAND initialization failed, do not read NAND data */ { gNandInfo.m_rxRet = Drv_NandFlash_Read(Dev_NandFlash, gNandInfo.m_ddrAddr, gNandInfo.m_nandAddr, gNandInfo.m_picLength); if(0 == gNandInfo.m_rxRet) { gCrc32 = CalCRC32((uint8_t *)gNandInfo.m_ddrAddr,gNandInfo.m_picLength);
if(0xEDD10215 == gCrc32) { gNandInfo.m_checkRet = 1; } } }
}

Nancy Wang：
algProc与警告中的algProcess命名也不相同，可以搜一下algProcess,或者上传您的工程也可以。
,
Duan Siyu：
好像上传不了文件，algProcess是文件名。
