Caution in Using JTAG Pins in Embedded Systems
In embedded systems such as STM32, if it is necessary to disable the JTAG function pins to avoid floating voltage issues (such as a residual voltage of 0.66V), the following key measures should be followed: 1. Causes and Risks of Voltage Residuals Internal Weak Pull-Up/Pull-Down ResistorsThe JTAG pins (such as TMS, TCK, TDI) typically have … Read more
