![]() ![]() Any loading circuitry should be buffered to avoid conflicts (for example, connecting ASSOCIATE / DIO5 to the gate of a MOSFET which drives the LED). The pinouts for various JTAG interfaces (linked above) are shown in Figure 2. JTAG cable for connection to a standard JTAG 20-pin pitch 2.54 mm connector Supports JTAG communication, up to 9 MHz (default: 1.125 MHz) Supports serial wire debug (SWD) up to 4 MHz (default: 1. These components include xtensa-esp32-elf-gdb debugger, OpenOCD on chip debugger, and the JTAG adapter connected to ESP32 target. The following table indicates the JTAG signal name, the primary connection pin on the device, the secondary connection pin, and the secondary signal name.ĬAUTION! Do not load the secondary pins with circuitry that might interfere with JTAG programming (for example, an LED tied directly to the ASSOCIATE / DIO5 line). Three of these pins are also connected to a second pin on the device and are used for separate functions. Many PLCs hold the contact pad with 12-24 JTAG pins organized in 2 rows, e. There are four JTAG programming pins on the XBee/XBee-PRO Zigbee RF Module through which firmware can be loaded onto the EM357 processor. Although most PLC vendors remove the header from the JTAG interface on a circuit board, the contact pad is still visible. ![]() ![]() Special instructions for using the JTAG interface ![]()
