ESP32-C3-DevkitM-1 and ESP-PROG and Platformio and VSCODE (Win10) problems

[joseMiguel]

Hello,

I am trying to debug ESP32-C3-DevkitM-1 board with ESP-PROG debugger.
(I have already used built-in USB/JTAG interface, but i faced lot of problems with freertos, so i decided to go trough ESP-PROG)

1) I have burned the DIS_USB_JTAG fuse by typing :
>espefuse.py --port COM11 burn_efuse DIS_JTAG_USB 1

2) I have connected GPIO10 to +3.3V
and ESP-PROG to ESP32-C3-DevkitM-1

ESP-PROG <---------> ESP32-C3-DevkitM-1
(Pin 2) ESP_TMS <---------> (Pin 11 right side) MTMS
(Pin 4) ESP_TCK <---------> (Pin 9 right side) MTCK
(Pin 6) ESP_TDO <---------> (Pin 8 right side) MTDO
(Pin 8) ESP_TDI <---------> (Pin 10 right side) MTDI

remark :
in the schematic the ESP-PROG, ESP_TDO is an input and ESP_TDI is an output.

3) I have used the Zadig software (Dual RS232-HS (interface 0) replaced by WinUsb)

I have the following message in the DEBUG CONSOLE

Could you help me please,

Thank you in advance

Hello,

For those who want to use Platformio and the ESP_PROG debugger on Win10
I give your my platformio.ini who works

Code: Select all

[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1
framework = espidf

; Set optimization level and amount of debug information generated by the compiler
debug_build_flags = -O0 -ggdb3 -g3
; JMJ tests two lines below
build_flags = -D PIO_FRAMEWORK_MBED_RTOS_PRESENT
lib_ldf_mode = chain+

upload_port = COM11
monitor_speed = 115200


debug_tool = esp-prog

; fixed speed in kHz
debug_speed = 8000


[debug_openocd]
debug_server =
    ${platformio.packages_dir}/tool-openocd-esp32/bin
    -s
    ${platformio.packages_dir}/tool-openocd-esp32/share/openocd/scripts/
    -f
    ${platformio.packages_dir}/tool-openocd-esp32/share/openocd/scripts/board/esp32c3-ftdi.cfg
    -c 'usb_vid_pid 0x0403 0x6010'
    ;ftdi tdo_sample_edge falling

[debug]
debug_server = 
    ${platformio.packages_dir}\\toolchain-riscv32-esp\\bin
    -singlerun
    -if
    ;JTAG

    -select
    JTAG
    -port

    esp32c3

debug_init_break = tbreak app_main

Have a nice end of year
