Shikra jtag. JTAG on-chip debugging: Extracting passwords from memory

But why extract the firmware from an electronic device? Discussing how computer addressing works is beyond the scope of this blog it is not a simple subject! There are several JTAG adapters available on the market, some quite expensive for professional use and others more accessible, some of which are open hardware:. A brute-force tool like JTAGulator can also be very useful! Thanks for all the help. Using the lowest pin number decreases the number of permutation to iterate through and ultimately speeds up the identification process. For now, it is enough to understand that the location of the Stack Pointer contains the last value pushed onto the stack of things in memory RAMserving as the starting address from where user space memory can be accessed.
