Publication Date:  2012-07-27 Views:  53 Downloads:  0

Handling Process
Use jtag to upgrade the bootrom of fada 
upgrade lpu  jtag 16  cfcard:/V300R001C01B052.CC  fad_bootrom
Where the number 16 is slot ID, and V300R001C01B052.CC is the file.
The operation will take 30 minutes. 
Run check version command after upgrade, and then upgrade the other elements. 
Root Cause
The flash is locked because the loading of files fails, and no file can write into the flash. So the measures to replace the slot or revert to the old version cannot help. 
Suggestions
