ESP32-WROVER-KIT v.4.1 and JTAG with openocd don't recognize the ESP32
Posted: Wed Oct 10, 2018 2:03 pm
Dear all,
me and my colleague need a help, we've been trying for two days and we have search everything but at the end
we are not able to use our two boards of ESP-WROVER-KIT V.4.1 for debug with openocd, some points
- upload a test FW like hello_world or blink works fine and the programs runs
- we have followed the Espressif tutorial step by step, and others found on internet
- controlled tens times the jumpers (same settings in the photo of the tutorial)
- nothing connected to the pins strip
- reinstalled the drivers
- used both USB and an external power source
- .. a lot more
nothing, we are convinced that it is a trivial oversight but we are not able to find it.
When we launch at command line with the command :
bin/openocd -s share/openocd/scripts -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover.cfg
this is the output :
Open On-Chip Debugger 0.10.0-dev (2018-07-24-09:39)

none separate
adapter speed: 20000 kHz
esp32 interrupt mask on
Info : ftdi: if you experience problems at higher adapter clocks, try the command "ftdi_tdo_sample_edge falling"
Info : clock speed 20000 kHz
Error: JTAG scan chain interrogation failed: all ones
Error: Check JTAG interface, timings, target power, etc.
Error: Trying to use configured scan chain anyway...
Error: esp32.cpu0: IR capture error; saw 0x1f not 0x01
Warn : Bypassing JTAG setup events due to errors
Info : esp32: Debug controller was reset (pwrstat=0xFF, after clear 0xFF).
Info : esp32: Core was reset (pwrstat=0xFF, after clear 0xFF).
....
the problem is the same in both board.
anyone have any suggestion ?
thank you in advance.
