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;
2. After entering privilege mode, use h-stack command to get the stack information for reset;
3. Add a command: h-vos mem addr 0x2ff0-0x7000, which can print the contents in register of the stack.
Suggestions
After resetting the equipment (not for power-out), we gather the stack information for analysis by R&D, facilitating fast location of the problem.
