TI中文支持网我这出现了一个问题，在主程序中在MSM段定义了一个共享多核同步变量isDATAInitialized。在中断程序中也做了声明，但是该变量在中断程序中无法修改，已经维护了cache一致性。
编译的时候有如下warning，一直不清楚是什么意思。
Section ".MSRAM" requires a STATIC_BASE relative relocation, but is located at 0x0c000000, which is probably out of range of the STATIC_BASE. STATIC_BASE is located at 0x00828818. Might be required to correct placement of ".MSRAM" so it lies within 0x8000 of the STATIC_BASE. SAR_IMAGE_PROCESS C/C++ Problem
relocation from function "IPC_ISR" to symbol "isDATAInitialized" overflowed; the 26-bit relocated address 0x2e05dfa is too large to encode in the 15-bit unsigned field (type = 'R_C6000_SBR_U15_W' (13), file = "./ipc_interrupt.obj", offset = 0x0000068c, section = ".text") SAR_IMAGE_PROCESS C/C++ Problem

请问waring出现的原因，和改变isDATAInitialized的办法。直接往该地址写值是可以的，但是感觉不规范。
Andy Yin1：
什么叫在中断程序中对变量进行声明？共享变量定义及声明均需要是全局的。
