Do not forget to replace the drivers using the Zadig driver installer. I did and it did not work. I had to go and watch the video a second time and it worked once I replaced the drivers. Interestingly enough, the code always goes to the FreeRTOS when debugging at the source code level. It makes it even more obvious that FreeRTOS is an integral part of the ESP32 Arduino libraries. Debugging will lead you there no matter what. I simply stepped out of the FreeRTOS stuff because I was more interested in my code than any RTOS kernel stuff.

YES! Andreas, You're absolutely right : this will be a true life changer for me as well. I'm used to work with debuggers in the programming languages I use on a dayly basis and and always found it more than tedious to do my arduino programming without. Especially as I am not as safe and sound in C++ as I am inmy other languages. -When it comes to referencing and dereferencing of pointers I sometimes have to enter the area of guesswork or trial and error. - Optimizing code by testing different variants and approaches is very time consuming.When it comes to debuging. - Debugging data types via the serial monitor is not always working as expected, as it does its own conversions or requires manual conversion prior display, which sometimes covers up the problem. - Stupid errors like expecting a float value froma division of two integers without conversion - .... I actually knew about the inline debugging capabilites of platformio, but at the time I read about it, it was available in the commerical version only and was no option for the projects I did at that time. So I did not pay attention, when You made this video back then. Just when I accidentally heard about the esp-prog a few days ago, I looked into it again and remembered that You had done a video on that subject. Now I find it hard to wait until I get the debugger. I've not directly found a source that delivers from within Germany. So it seems, I'll have to get it from China and be patient. Despite the fact, that on an esp8266 only a few usable pins remain,I still think,it will be a huge support even for these boards. Especially,when it is about conceptual / structural debugging.

Although I'm familiar with inline debugging from other platforms, it's rather complicated to use for ESP32 until the board manufacturers will use a standardised connector. My standard way of debugging, 99% ESP8266, is to use MQTT. In this way I can both "print" messages and also input data if I want to. I can do similar things as conditional breakpoints or logging, or conditional input controlled by MQTT. My first upload with a new project is always a simple standard sketch that replaces serial load with OTA over Wifi and has some standard topics for debug and reporting when a devices boots or restarts. In this way it is really fast to make changes to the code for debugging purposes. I never use the serial terminal since I'm used to making continuous improvements to my sketches with the devices long away from my computer. OTA and MQTT makes it possible to make changes and corrections without having the device connected physically. "JTAG" over Wifi supported by the chipset itself would however be very useful, with even having to use a JTAG physical connector...

@@bollie9752 No. It's basically just having a debug topic for outgoing messages instead of Serial.print and then listening to this topic in a shell or by logging to a file. If you want to change the program flow in some way you can have incoming debug topics for values or triggers. A trigger can just set a variable or a simple if statement in the code can do something that affects the program flow e.g. by assigning some variables, skipping a section of the code or whatever. I only do this when something is not working as intended but I also have a standard topic for all my clients and a listener on my server that logs this to a text file. I use this to check when a device has rebooted and to which IP/mac-address, the RSSI dB value, name and version of the sketch etc. Like this (one row in the log file): 19-06-23 11:43: NeoPixelAlertIndicator1 BOOT 192.168.0.154 60:01:94:39:72:85 RSSI(dBm):-54 NeoPixelAlertIndicator 1.4 2018-08-25 Hans Palm

Then I set "debug_tool = jlink". PlatformIO recognized the J-Link, but when running the debugger, I got an error, and the debugger stopped.

For your information you could of declared "localVariable" as static like :- static int localVariable = 0; With the static keyword the variable will not be destroyed when out of scope (exiting the loop routine) It will retain its value the next time loop is called unlike your dynamic variable that gets created each time you call loop. The "= 0" (assignment of zero) only gets called once during creation. The reason why this may be a better choice is because no other routine can see or more importantly change the contents of "localVariable" Which may be a better choice that making "localVariable" accessible to everyone (all routines) in some cases. Depends whether you want other routines to see the variable. Welcome to the world of debugging. 😃

Today I got my esp-prog board to work on my mac with help of this video (which inspired me to buy the esp-prog in the first place). I now am able to both program (upload), monitor and debug the ESP32 (I tried the SBC-NODEMCU-ESP32 from JOY-IT) over a single USB connection. I did run into some small problems. My advice is to install the official FTDI VCP driver for the MAC OS you are running (I'm at a beta of 10.15.5 currently). Then LEAVE THE PORT SETTING FOR THE DEBUG PORT EMPTY, but use the 'xxx01' port for the upload and the monitor port. Still I don't like the VS Code environtment that much. Maybe after some time I will learn to appreciate it. But even if I don't like it for programming, I still can use it to debug the ESP32 projects now. Next on my list is to create a jig to easily cable up the NodeMCU to the ESP-prog. I'm thinking about designing a PCB with feed-through header pins or so.

Btw. If somebody is interested how JTAG debugging works: The processor get's stopped .. all important registers of the CPU get copied into 'shadow' registers and this shadow registers can be 'clocked' out serial using a special protocol through the connected lines. Also memory can be read and written that way. Sometimes CPUs have special debug registers that can be adressed also ... btw. many chips support a JTAG interface .... the cool thing is that you can chain them together if you have a larger circuit, but then it get's a real serial mess ;-)

This sure would have helped last summer with debugging the tank communications problems. That brings up another situation where serial debugging does not work well Debugging a crash. The serial writes are cached; so, the messages go out after a delay - and sometimes not at all when a crash occurs. This can mislead you regarding where the code is crashing.

I remember "poor man's debugging" in C using printf statements. I then made a debug_print macro that was a printf embedded inside a "#ifdef _debug". That way I could recompile with or without _debug defined. This totally confused me. When I compiled and ran the program without debug, it misbehaved. When I recompiled with debug, the problem went away! This had me scratching my head. Veteran coders probably have figured out why running with debug turned on "fixed" the problem. Yep, the problem was timing dependant. The printf statements slowed down execution just enough that the timing worked!

The ARM boards use the ST-Link style interface, which is logically similar to JTAG, but a different wire-protocol (SWD - Serial Wire Debug). I'm pretty sure that the ESP32 microprocessor cores do not implement the ARM debugger port in their hardware. Thus the need for a JTAG physical interface. The adapters referenced (including ST-Link style) translate higher level GDB primitives (read/write memory, examine/set CPU registers, etc.) into specific debugging register accesses, via some physical protocol (SWD or JTAG, depending on the CPU and debugger interface.)

@victoriamotion79802 жыл бұрын
@@AndreasSpiess I see; for multiplatform Arduino, PlatformIO sounds like a good choice. About the board I don't know, just at 12:25 you're showing (for many hobbyists) relatively expensive JTAG adapter. And I'd say it's enough to grab some board with one of those FTDI chips. ESP-PROG (for about 15€ on Ali) for example, is nothing but a FT2232H based board which uses two channels from the chip; one for JTAG, one for UART programming. But it's fine to just get one channel version with FT232H (for about 8€ on Ali). It can do both, just to the target module needs to be connected either to UART or JTAG pins. And it's not even uncommon that users program target chips over JTAG (right before debugging session starts), so that whole UART thing might be dropped, IMHO.

One, not just "newer AVR's" support jtag. Just going one step above 328's also adds JTAG. I know I've seen the pinouts on the 644/1284 datasheet. So you can even pick up JTAG with a chip supported by Arduino that also comes in a DIL package. Second, you made my inner Tux cringe with that Windoze IDE thingy. Will this work with Atom and Platform IO? Lastly, while I have watched it at least twice, and still haven't tried it, LadyAda did a live stream a few years ago showing how Adafruit uses OpenOCD with a raspberry π.

Nice explanation of inline debugging. Thank you. Only one note and some "provocative" questions. There are lot of reasons why inline debugging is not so popular like in the past, for example in the time of 8080 processor (1985). The reasons are multithreading and thousands of external events per second from wifi, i2c, spi, one wire sensors, interrupts, buttons... External events is hard to stop. When you stop processor you lose real time, connection to the sever, external events and many more... Ofcourse for very simple applications like debugging of blinking led it is possible. But for simple application do we need it? Is it posible to replace "stupid" real time logging via serial interface with inline debugger? What is main task of inline debugging?
@AndreasSpiess5 жыл бұрын
You are right with your comments. But since we do small projects with our MCUs it still can help. I would not recommend it for a server ;-) Maybe you can set the breakpoints at particular areas where you can stop the CPU without hurting the functioning. Or you debug your sketch without WiFi at the beginning... Just ideas. Debugging real-time systems always was tricky, even back then.

I pretty much ditched Arduino or at least AVRs completely, because of their very limited and outdated features and am using STM32s (hard to beat 2$ st-link programmers/debuggers). Up to now I always set up eclipse, which was a real hassle to do and with every project I started I had to learn again what I had to select in the settings ;) . But when it worked, eclipse was really powerful and extensions like "GNU MCU eclipse" made it much easier lately (the "where and what" to set became a simpler "where" to set).
