1、经确认，现场使用的bootware版本1.21不支持新版本R7624P09，导致启动时无法正常加载版本。 

2、对于现网升级前的R7187版本，默认携带的bootware版本是1.46，但是老的1.21版本不支持自动升级到1.46，需要手动指定升级。  

1、测试如下，原有设备bootware版本是1.21，加载R7187后，bootware版本并未升级，如下：

MPU(M) 0:                                                                                                                          

Uptime is 0 weeks,0 days,0 hours,25 minutes                                                                                        

BOARD TYPE:         LSU1SUPB0                                                                                                      

DRAM:               8192M bytes                                                                                                    

FLASH:              500M bytes                                                                                                      

NVRAM:              512K bytes                                                                                                     

PCB 1 Version:      VER.A                                                                                                           

Bootrom Version:    121       ------1.21版本           

2、手动升级主控的bootware。                

 <ZJK-SZF-S10508>bootrom update file flash:/S10500-CMW710-BOOT-R7187.bin slot 0                                                     

This command will update the Boot ROM file on the specified board(s), Continue? [Y/N]:y                                            

Now updating the Boot ROM, please wait...                                                                                          

 .............Done.

3、重启设备，版本升级为1.46，随后加载R7624P09正常。

  MPU(M) 0:                                                                                                                          

Uptime is 0 weeks,0 days,0 hours,38 minutes                                                                                         

BOARD TYPE:         LSU1SUPB0                                                                                                      

DRAM:               8192M bytes                                                                                                     

FLASH:              500M bytes                                                                                                     

NVRAM:              512K bytes                                                                                                      

PCB 1 Version:      VER.A                                                                                                          

Bootrom Version:    146       

4、本次升级版本失败，是由于版本跨度太大，老的bootware无法自动升级，并且不支持新的版本导致。针对这个问题，可以提前手动升级bootware版本（bootrom update命令），再指定新版本文件升级设备。
