unidbg黑盒调用so的时候报错，麻烦大佬帮忙看下

lxb3333111

报错信息为： [16:50:03 866]  WARN [com.github.unidbg.arm.AbstractARMEmulator] (AbstractARMEmulator$1:67) - Read memory failed: address=0x0, size=4, value=0x0, PC=RX@0x400bec90[libc.so]0x18c90, LR=RX@0x400021a5[libocstool.so]0x21a5

这是找内存地址0x0失败了吗，应该怎么处理，可以通过IDA判断这个地址的作用吗。谢谢大佬们
