In the process of FPGA development and learning, a key step is downloading to the board. Achieving hardware “hard presence” is very important, and generally, the JTAG port is more commonly used. Therefore, I believe that some experts must have encountered issues with the JTAG port becoming unresponsive or damaged and unable to be used. … Read more
JTAG is an IEEE standard (1149.1) developed in the 1980s to address manufacturing issues in electronic boards. Today, it can be used for programming, debugging, and probing ports. But first, let’s look at JTAG’s original purpose: boundary testing. Boundary Testing This is a simple electronic board (also known as a “Printed Circuit Board” or “PCB”) … Read more
