ESP32-S3 crashes when switching between screens

What do you want to achieve?

Switch between screen 1 and 2 with a button

What have you tried so far?

Create a button and adding an event to change between screen 1 and 2

I have a custom PCB with an ESP32-S3 MCU on it. I want to swap between screen 1 and screen 2 with a button, and I have added a button for each screen to trigger an event to swap between the screens. Inside the SquareLine editor, it works as expected, but when I export te UI code to my project and try to press the button, the MCU goes into panic mode. Is there a known bug with swapping between screens? Any suggestions on what to try next? I am using a RGB LCD with this example code for esp-idf: esp-idf/examples/peripherals/lcd/rgb_panel at master · espressif/esp-idf · GitHub

Best regards,

Please enable the logging of LVGL. Hopefully it will show something useful.

Thank you, I was not aware that this is an option. I will try it and get back to you.

Ok, so I have tried turning on the logging. When I did, I got a lot of error messages, similar to those described here [IDF 5.0] type 'uint32_t' {aka 'long unsigned int'} (IDFGH-8001) · Issue #9511 · espressif/esp-idf · GitHub. Anyways, I fixed the issues by casting all the variables as integers, and it compiled successfully. Unfortunately, no relevant logging info showed up before the system crashed again.

Forgot to mention this earlier, but I was running LVGL 8.2.0, so I thought I’d try upgrading to 8.3.0 to see if that would resolve the issue. Now I am able to switch back and fourth between the two screens once, but then the same happens. When I comment out the “lv_scr_load_anim” function, nothing happens and the system is stable, so I’m guessing it has something to do with the integration of what happens in lv_scr_load_anim and the ESP32-S3 that is not working very well together… Any further suggestions?

EDIT: seems to be related to this issue:

Can you send an example project here or via email (contact@squareline.io) so that we can reproduce the issue? I think it will crash in the simulator too.

Sure! I have added you to my Github repository, and will send you a link with the repo on email. Thank you for looking at this.

I’ve just tried it out in a simulator on PC but unfortunately it haven’t crashed for me. :frowning:

I’ve noticed that you are using LVGL v8.2.0. SLS already supports v8.3.4. So please try out with the latest version too. You can easily select the LVGL version in project settings menu:

Ok, so that would indicate that I have not done something bad/illegal in the SquareLine editor. It has also been working for me inside of the SquareLine editor when I use the simulator there.

I will have a go with the 8.3.4 version and see if that does anything.

While testing a bit, I sometimes manage to go back and fourth a few times before it crashes, so it seems to be working initially. Maybe the crashes are caused by a memory leakage, bad timing or something along those lines?

I don’t think it’s a memory leak, because it’d show an “out of memory” error in LVGL’s log.

I rather think that it’s some kind of memory config issue, like using non DMA-able with DMA or so.

I have some ideas to test:

  1. Create a long list like in lv_example_list_1, make it really large with a lot of elements, and start to scroll it like crazy. If it crashes, then the issue is related to refreshing large areas and not the screen change.
  2. Run lv_demo_stress(). There is no screen change here either, just a lot of redraws.
  3. Make the screen change buttons very large and in the flush_cb call only lv_disp_flush_ready(drv);.
  4. Disable display rotation.
  5. Increase the stack size of the gui task. 4096 should be enough, but it’s worth a try
  6. Increase LV_MEM_SIZE.

Thank you for your suggestions, here is a report from my testing:

  1. Updated LVGL to 8.3.4, seems to have made no difference.
  2. Used the example from lv_example_1 and added a huge amount of elements. Can scroll trough the list without any problems.
  3. When running lv_demo_stress(), it crashes after about 5 seconds.
  4. When I only call lv_disp_flush_ready(drv); here, nothing is drawn obviously, but when I press the display in order to trigger the change of screens, the log output is as shown below.
  5. Tried disabling rotation, no difference.
  6. Increased the stack size of the gui task by a factor of 4, no difference.

Log output when doing 3. is shown below:

Updating this continuously as I get around to test everything. Just noticed I did not actually activate the LV logger before, so now I actually have some output from it. Will add output in separate reply.

Rebooting...

I figured out what was causing the issues I’ve had. The lv_disp_draw_buf_init() function takes in the uint32_t size_in_px_cnt parameter, which I believe is the draw buffer size (?). This number was set to 480 * 10000 = 4.8MB if my thinking and math is correct. So I guess since the .flags.fb_in_psram = true, // allocate frame buffer in PSRAM flag was set, and the PSRAM on the ESP32-S3 module I am using is 2MB, I allocated more memory than available. Had an identical PCB (which I had some trouble with before, thus the long wait before testing the code on it) with a 8MB PSRAM MCU, where the code with 4.8MB buffer size ran without problems. I am not super familiar with how LVGL is built and how the memory allocation etc works, so I’d be very happy if you would comment on my thoughts here and maybe give a short explanation @kisvegabor. Also thank you for all the ideas you presented before, I have learned a lot by trying your suggestions.

I’m also not super familiar with how the ESP drivers are built, but it you want to save some RAM, partial buffering can be an option too. Like this:

    ESP_LOGI(TAG, "Allocate separate LVGL draw buffers from PSRAM");
    buf1 = heap_caps_malloc(EXAMPLE_LCD_H_RES * 100 * sizeof(lv_color_t), MALLOC_CAP_SPIRAM);
    assert(buf1);
    buf2 = heap_caps_malloc(EXAMPLE_LCD_H_RES * 100 * sizeof(lv_color_t), MALLOC_CAP_SPIRAM);
    assert(buf2);
    // initialize LVGL draw buffers
    lv_disp_draw_buf_init(&disp_buf, buf1, buf2, EXAMPLE_LCD_H_RES * 100);

Yes I have seen that been done. Thanks for the feedback.
