To program an ESP32-S2 chip using the JTAG interface with the ESPLink v1.2 Debug Probe Tool, follow these steps as outlined in the user manual:
1. **Openocd Installation:**
- Clone the Openocd repository for ESP32:
```
$ git clone https://github.com/espressif/openocd-...
$ cd openocd-esp32
```
- Bootstrap, configure, build, and install Openocd:
```
$ ./bootstrap
$ ./configure
$ make -j
$ sudo make install
```
2. **Attach to ESP32-S2:**
- Run Openocd with the following command:
```
$ sudo ./src/openocd -s /home/pi/oss/openocd-esp32/tcl -f tcl/interface/esp_usb_bridge.cfg -f tcl/target/esp32s2.cfg
```
3. **Debugging:**
- Once attached successfully, open another terminal for debugging.
4. **Debug with Gdb:**
- Use the following commands to debug with Gdb:
```
$ xtensa-esp32s2-elf-gdb -ex 'target remote 127.0.0.1:3333' ./build/blink.elf
(gdb) info reg
(gdb) s
(gdb) continue
```
5. **Debug with Telnet:**
- Use Telnet to debug with the following commands:
```
$ telnet localhost 4444
reset
halt
reg
step
resume
```
By following these steps, you can effectively use the ESPLink v1.2 Debug Probe Tool to program and debug an ESP32-S2 chip using the JTAG interface.
