My router has the following pin layout between flash memory and MCU:
The big chip is the MCU from a Sercomm H300s router.
What I want is to analyze the signaling between 2 chips using the most accessible pins in the MCU. But I also want to avoid soldering.
Also, how I can record any binary data exchanged between MCU and Flash memory chip in my computer, do I need a bus pirate or a logic analyzer?
