Hi there, I’m having an issue while attempting to debug an esp32-cam module
with an CJMCU-232H (FT232H Single channel) module (No dual channel FT2232H) as JTAG interface with Arduino framework.
It’s just basically hitting the same line over and over in the asm and never moves to my C code, no matter if I hit play/next/step in/step out
I’m on PlatformIO, version 4.3.2a1 (dev channel)
this is my platformio.ini
[env:esp32cam]
platform = espressif32
board = esp32cam
framework = arduino
monitor_port = COM9
monitor_speed = 115200
upload_port = COM9
upload_speed = 1500000
debug_init_break = tbreak setup
debug_tool = custom
upload_protocol = custom
debug_server =
$PLATFORMIO_HOME_DIR/packages/tool-openocd-esp32/bin/openocd
-s
$PLATFORMIO_HOME_DIR/packages/tool-openocd-esp32/share/openocd/scripts/
-f
$PLATFORMIO_HOME_DIR/packages/tool-openocd-esp32/share/openocd/scripts/interface/ftdi/esp32_devkitj_v1.cfg
-f
$PLATFORMIO_HOME_DIR/packages/tool-openocd-esp32/share/openocd/scripts/board/esp-wroom-32.cfg
-c 'ftdi_vid_pid 0x0403 0x6014'
I wired it according to the last section named “Adapter 3: Generic FT232H board” in the following post: https://medium.com/@manuel.bl/low-cost-esp32-in-circuit-debugging-dbbee39e508b
Only difference is I didn’t edit the esp32_devkitj_v1.cfg file since passing params as custom debug options seemed a cleaner solution which should survive future upgrades
This is what my vscode and zadig looks like:
and the following is the output

I tried also the simple following code:
#include <Arduino.h>
int LED_BUILTIN = 2;
void setup()
{
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop()
{
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
but I had to add “build_flags = -g -Og -fno-inline” because of xtensa-esp32-elf-gdb crash (IDFGH-353) · Issue #2343 · espressif/esp-idf · GitHub
also I get stuck many times on “Info : Flash mapping XYZ:…” and I have to just restart the board and the debugging process
I tried
platform = https://github.com/platformio/platform-espressif32.git#v2.0.0
and
platform_packages =
framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#idf-release/v3.3
and several other permutations and versions of these two with similar unsuccessful results
Any help would be very much appreciated.
Thanks,
Jacopo
