In this post, you can free download the latest setup of JTAG Android. It is free to process to defined and typically used by chip firmware developers in order to debug the code as they write it. Sometimes we are going to familiar with JTAG because we are using tools with a JTAG interface.
It allows you to do things like iterate the CPU clock cycle by cycle so you can see where the code might be going wrong, but interestingly for us, it also has loads of other functionality. Processors often use JTAG to provide access to their debug/emulation functions and all FPGAs and CPLDs use JTAG to provide access to their programming functions.
There are several sites which are providing free setup files. For this demonstration, we’re going to be using its ability to extract memory. We’ll be looking at Android but before we get into that I want to compliment Apple on the security of their JTAG ports.
They don’t publish the protocols used to communicate with them, and to the best of my knowledge no-one has successfully communicated with an Apple JTAG port, other than their own developers of course. Now download the latest setup of JTAG Android from download section menu.
