利用ESP-Prog Debug esp32-dev-kit

1. 下圖是ESP-Prog的管腳定義

 

2.下圖是esp-dev-kit中HUZZAH32 feather系列的管腳定義

 

3.Identify all pins / signals on JTAG interface and ESP32 board, that should be connected to establish communication.

 

 

 

	ESP32 Pin	JTAG Signal
1	CHIP_PU	TRST_N
2	MTDO / GPIO15	TDO
3	MTDI / GPIO12	TDI
4	MTCK / GPIO13	TCK
5	MTMS / GPIO14	TMS
6	GND	GND

4.連接後如圖：

5.利用zadig更新驅動：

 

6.更新後JTAG Interface由COM17變成了Dual RS232-HS

7.若不更新驅動，會提示如下錯誤：

 

8.打開Openocd

openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg

 

9.若不打卡OpenOCD會提示

10.debug模式打開ok
