When the breakpoint is … Read more
JTAG, as commonly referred to, can be roughly divided into two categories: one is used for testing the electrical characteristics of chips to detect any issues; the other is used for debugging. Generally, CPUs that support JTAG contain both modules. A CPU with a JTAG Debug interface module can access the internal registers of the … Read more
Background In the previous section on hardware security, we used a programmer and UART debugging pins to extract the firmware from the Tenda AC6 router, mastering how to obtain firmware through the UART interface and gain terminal access for debugging analysis. Besides the commonly seen UART interface, we often encounter JTAG interfaces on PCB boards, … Read more
Xilinx‘s JTAG cable can directly program SPI/BPI. Many users who are not familiar with the Xilinx development environment may have questions when encountering this programming mode for the first time. How does the FPGA bridge between JTAG and Flash? Is there a dedicated circuit inside the FPGA to achieve this function? Actually, no. The FPGA … Read more
