[closed] moving to cmake/IDF V4.0 is causing problems

Hi all -

As a precursor to using the Eclipse IDE for ESP32 development, I changed my IDF to v4.0 and started using cmake.

Now, when I flash my program, something odd happens to the console output:

Code: Select all

This is very repeatable. It also doesn't appear that my program is running, though without the console messages, it's hard to know what's going on. Any ideas what might be happening?

Hi mzimmers,

I've seen similar results (UART baud rate changes to some invalid value) when the Wi-Fi was initialized with a wrong/mismatched libphy version. Is it possible this is happening, are any submodules out of date? The last log lines indicate app_main() is about to be run, what does your project's app_main() function do?

You mentioned that switching to cmake is a factor for this. If you build the same project with the same IDF version and make, does it work OK?

Hi Angus -

I'll take a closer look in the morning, but I think I lost some of the necessary make files for using make in my (admittedly hasty) conversion. I can look into the WiFi possibility. Which component contains libphy -- LwIP?

Thanks...

It's part of the esp_wifi component. "git submodule update --init --recursive" should rule it out.

You'll also see build warnings if the build system detects some modules are out of date.

I did the submodule update command with the same results, so I guess it's not a submodule problem.

I'm having problems re-creating the msys build environment, but I'll keep working on that.

Here's where I am now:

- did a git checkout of IDF v3.3, and rebuilt...app runs fine.
- did a git checkout of IDF v4.0, and rebuilt...get this:

This now repeats indefinitely, which is a change from how it was working before.

I did have to make a few code changes for V4.0:

- needed to change this path: #include "esp32/rom/crc.h"
- needed to change initialization of a struct:

Code: Select all

// this initialization works for esp-idf v4.0.
const ledc_timer_config_t LED_TIMER_CONFIG = {  LEDC_HIGH_SPEED_MODE,
                                                LEDC_TIMER_10_BIT,
                                                LED_TIMER,
                                                5000,
                                                LEDC_AUTO_CLK};
// this initialization works for esp-idf v3.3.
//const ledc_timer_config_t LED_TIMER_CONFIG = {  LEDC_HIGH_SPEED_MODE,
//                                                {LEDC_TIMER_10_BIT},
//                                                LED_TIMER,
//                                                5000};
- added this to a switch statement: __attribute__((fallthrough));

And I'm running the idf.py build command from the ESP-IDF command prompt.

If I try to build using msys32, I get the warning about the toolchain (haven't figured out how to get rid of this yet).

So...I'm kind of at a loss to explain this, and would greatly appreciate any ideas.

Update: I ignored the build warnings when building with V4.0 and flashed using make flash: behavior is not identical to that when building with cmake, but very similar: gibberish output to the console port. None of it is printing, but it's at least the right number of characters, so it's probably some UART setting.

So, it looks like it's V4.0, not cmake.

EDIT: the above isn't 100% true. I hit the reset button on the board, and received console output identical to that when using cmake. Further evidence that the problem is with V4.0 and my app.

Thanks for the additional details. It's hard to tell what this could be without knowing what your project does.

Can you do some differential testing by disabling parts of your app's startup code and seeing if the problem goes away? Or use a debugger or some additional printf statements (and flushing out stdout) in order to figure out which step is introducing this problem?

EDIT: What crystal setting does your project have? https://docs.espressif.com/projects/esp ... l-freq-sel - if it's set to autodetect, can you try changing it to the actual crystal value?

Hi Angus -

Here's the top of my app_main():

Code: Select all

extern "C" void app_main()
{
    vTaskDelay(portMAX_DELAY);
    ...
Here's the relevant passage from my sdkconfig file:

Code: Select all

CONFIG_ESP32_XTAL_FREQ_40=y
# CONFIG_ESP32_XTAL_FREQ_26 is not set
# CONFIG_ESP32_XTAL_FREQ_AUTO is not set
CONFIG_ESP32_XTAL_FREQ=40
Thanks...
