esp32 wifi debugger for ARM Cortex microcontrollers https://github.com/blacksphere/blackmagic

Blackmagic Probe for ARM running on esp32 hardware

Based on the ESP8266 black magic port, only provides SWD ARM Cortex-M Debug Interface

It provides a wifi based, debug probe for ARM i.e. ST32L1 cortex processors https://github.com/markrages/blackmagic/tree/a1d5386ce43189f0ac23300bea9b4d9f26869ffb/src/platforms/esp8266

Changes

I merged JTAG support for riscv-esp32c3 however this is not tested.

If you connect an STM32 board and put it in boot mode, then you might be able to query some information with uart_scan.

You need to connect the UART pins

Merges latest from black magic main repo

Platform IO

The latest changes are tested with ESP32-C3

I also managed to build with an esp32-S3

Then I had to preform a workaround, by setting board to board = esp32s3-qio

If you have problems, Use Platform, Run Menuconfig Here you can change settings, Component config → ESP System Settings , Initialize Task Watchdog Timer on startup Dsiable the watchdog or find a way to prevent it from triggereing.

Using this as

You can use this software as one click debug, for a platform io project

debug_tool = blackmagic debug_port = 192.168.4.1:2345

Example config

[platformio]
src_dir = Src
include_dir = Inc

[env:blackpill_f411ce]
platform = ststm32
board = blackpill_f411ce

; change microcontroller
board_build.mcu = stm32f411ceu6

; change MCU frequency
board_build.f_cpu = 84000000L
framework =  stm32cube

debug_tool = blackmagic
debug_port = 192.168.4.1:2345

Up to date BMP

This repository is not updated with latest changes in BMP This other repository contains the latest version of BMP source https://github.com/Ebiroll/blackmagic

In order to build this repository in linux, do.

      > . ~/esp/esp-idf/setup.sh
      > cd src/platforms/esp32
      #Check the platform.h files amd make sure that the pins are OK.
      # check main.c for password and SSID of your wifi
      #Run build script.
      > build-esp32.sh
      #Upload the

However espressif might have changed this behaviour and it is might not be possible to build now. You must also pull the changes from upstream repo.

Status

Now it seems to work, I tried a RAK811 target. And the targets found in my arm_test repo The pins are defined here, http://docs.rakwireless.com/en/RAK811%20TrackerBoard/Software%20Development/RAK811%20TrackerBoard%20User%20manual%20V1.1.pdf

This is the debug compiled source code I use, https://github.com/Ebiroll/RAK811_BreakBoard

So

GND on ESP32 connects to GND on the RAK board, opposite to the boot pins
PIN 8 on ESP32-C3 connects to SWD_CLK
PIN 10 on ESP32-c3 connects to SWD_TMS

Pins are changed in platform.h

I (3119) event: sta ip: 192.168.1.117, mask: 255.255.255.0, gw: 192.168.1.1

Start the debugger,

target  extended-remote 192.168.1.125:2345

(gdb) monitor help

(gdb) monitor swdp_scan

(gdb) attach 1

Works like charm.

Trace SWO

It is possible to use trace swo if you configure it to use UART mode and 115200. You must also define thses in platform.h.

#define PLATFORM_HAS_TRACESWO 1
#define TRACESWO_PIN 6
// Workaround for driver, and to try STM info polling,
// It also allows you to use the UART from the debugger.
#define TRACESWO_DUMMY_TX 4

Note that the debugger needs to be attached in order to get output on the serial device. Here is an example of how to set up the swo for UART mode trace, https://github.com/Ebiroll/beer_tracker/blob/master/RAK811-Tracker/src/swo.c Add this,

#define CPU_CORE_FREQUENCY_HZ 16000000 /* CPU core frequency in Hz 32Mhz */
   SWO_Init(0x1, CPU_CORE_FREQUENCY_HZ);

However now it is more useful, as extra uart port if you do

(gdb) mon traceswo 115200
(gdb) mon uart_send Hello there

The uart data received within 500 ms will be printed in the debugger.

Here are some more useful information ow what is possible. https://github.com/orbcode/orbuculum

https://mcuoneclipse.com/2016/10/17/tutorial-using-single-wire-output-swo-with-arm-cortex-m-and-eclipse/

To start trace , do

(gdb) monitor traceswo 115200

esp32_blackmagic's Issues

Compile with SWO trace gives compilation issue

In command.c on line 375 traceswo_init() the function is missing a parameter so I supplied 115200. Hope it works.

Debugging stm32g4 through esp32s3

Thanks a lot for your project. Trying to repeat it my scenario where stm32g4 connected only by swd clk&io to the esp32s3-n16r8 module on the custom board. As far as I understand you use Platformio plugin to VCS, I repeated same toolchain.
Now project compiled with warnings but starting and successfully connected to local network.
Connection to the DGB on port 2345 from telnet or gdb client from cubeide(worked with internal gdb server) connection return "accepted new gdb connection" in the console, however no more actions happened.
Trying run your project in the debug mode, not sure PIO can do it.
Could you please other recommends to me

Think about a mechanism to sync with BMP

Hello,

it seems you simply imported the target directory. So your port misses a lot of target enhancements. A way to get into sycn with BMP would be nice, so that BMP user experience on the ESP is similar to the Native/PC-Hosted BMPs.

Any open ESP32 JTAG debugger?

If there is such a thing? It would allow a port to BMP.

Problems compiling using latest esp32-idf

Hello,
I'm trying to use esp32 as a BMP and found this.
I'm having troubles trying to compile with latest esp32-idf. Tried on platform.io on windows, through cmd.exe and with ubuntu with no success.
Problems with MakeFile and not existing CMakeLists.txt, with the instructions regarding the compile command (build_esp32.h / idf.py build) and so on. It must be very simple to fix/update the proper files and instructions (supposing i'm not doing anything wrong), so, could someone please help? Thanks!

Things I've done:

Had to change platfom.ini

unclear documentation....

Is this designed to be flashed to a 'stock' blackmagic board so you can debug an 'esp32' as the target device, or is this designed to be flashed to an esp32 so it acts like a blackmagic board and allows you to debug ARM devices as the target..?
