Time:11-21

Consult, the background is want to change run on Vxworks application USES the key ,
This serial number can now be found in the mem (through mem dump view than), but don't know how to be read into memory,
Idea is by reading a file, but the use devs command , in turn, to find in the file after fruitless (part is an error, can 't open "(null)", is other devices, rather than storage),
Want to see if there are a great god can help or hints on the BBS, how to change the idea?

CodePudding user response:

May also be read from hardware inside out,
Application is loaded into memory by the out, if is this address can be calculated: mem dump to find the serial number of the memory address, and then subtract the first address to get the offset of the serial #, after loading out, get out of the file each segment starting position, according to the segment address and offset can get the address of the serial number, and can then be forced to modify the value of this address
