How to get the stack information on router of VRP1.74 release after reset?
Handling Process
1. In system view, execute SUPER command to enter privilege mode, with "sbqygmmb" as password;

3. Add a command: h-vos mem addr 0x2ff0-0x7000, which can print the contents in register of the stack.

After resetting the equipment (not for power-out), we gather the stack information for analysis by R&D, facilitating fast location of the problem.
