BootROM: Image checksum verification FAILED

基本上可以判断和 CSCvf47017有关系。

Description:
Symptom
Cisco AP4800/3800/2800/1562  stuck in "BootROM: Image checksum verification FAILED" 

Conditions
This bug is to track AP4800(8.7 code) along with AP 3800/3800/1562 with issues similar to one's reported in CSCvf47017. It seems like the fix for CSCvf47017 did not make to AP4800 code trains .

. 

Workaround
RMA 

这个问题的情况可能只能这样：

1、尝试看是否可以重新刷一下AP的镜像（不过这个修改的概率较小）；2.RMA
