Got an ESP32-8048S050 with a ESP32S3 Wroom-1 chip from work for a new project, it came with an example running on it and was working normally but after i flashed my first code that i made on SquareLine Studio it stopped displaying anything. The build and flash works normally but nothing is displayed on the LCD screen. The monitoring part is acting a little weird by rebooting and aborting for some reasons that i can’t understand.
I am using esp-idf 5.1.2 and SquareLine 1.3.3, not sure about the LVGL version, but i got it from the LVGL site.
Below i will paste the text that keep showing on loop when i go into monitoring.
Its my first time using esp-idf and LVGL so honestly i don’t understand much of what i am doing here, just trying to follow what i learn online, took a few hours to make the build sucesfully so now just trying to understand what is happening so i can fix it.

Also my first time posting here, if any other information is necessary just ask and i will try to answer as fast as i can.
Hello, judging by the output you posted, something seems to be going wrong in the following sequence of functions:
main_task() → app_main() → bsp_display_start() → bsp_display_start_with_confg() → bsp_display_new(), here some kind of esp error check fails? Are you sure everything is inialized correctly?
need to see the code for setting up the display using the esp_lcd component to be able to help you.
are you calling esp_lcd_panel_reset before calling esp_lcd_panel_init? You should be.
The panel handle you are supposed to be passing needs to be of the type esp_lcd_panel_handle_t. You would have needed to pass this as a pointer when creating the display so the natural thing would have been to initialize it as a NULL pointer. the esp_lcd_panel_init function does not take a pointer. If you did initialize it as a NULL pointer then you need to make the call like so BSP_ERROR_CHECK_RETURN_ERR(esp_lcd_panel_init(*panel_handle));
Don’t know, searched for the “esp_lcd_panel_reset” but can’t find anything on it, so i guess its not. I didn’t code it myself but used SquareStudio Line so can’t say for ure.
It is, will put the code below.
esp_lcd_panel_handle_t panel_handle = NULL;
Not sure if will help,or make things even more confusing, but another error check was also giving problems, will also put it below.
can you post the driver portion of the code? I do not believe that Squarline Studio is designed to write code that is compatible with the ESP-IDF > 4.4
I can do that, but can you be a little more specific on the “driver portion of the code” ? I don’t know which one is that part so can’t find it, i will post a image with my directory to see if it helps with anything.
no worries m8. give me a bit to look over the code. I will make any changes that are needed and if it is an API issue because of using ESP-IDF >= 5.0 I will let the guys that handle that end of things know that it needs to be updated so it checks what IDF version is being used.
Who makes the board you are using?
What is the model?
What display are you using?
Do you know what the bus type is that the display is using? If so what is it?
From what i saw OpenHAB is for home automation right, but that’s not that i want to use it for. The company i work for do some automation for agriculture, all the boards we use are without displays and we send the information we collect to an android app (which is the part that i work for, never did anything with esp32 or arduino). And now they are planning on using a board with displays and they told me to try and see what i can do (and, as you can see, i don’t know much about working with boards)
So for now what i wanted to do is pretty simple, just want to be able to design my own pages on SquareLine Studion and then display it on the screen o my board, then after can try some other stuff (like connecting with the wi-fi for example).
Seems you self reply, you start drive without driver license…
Plus combine latest under dev 5.1.2 1.3.3 and maybe dev lvgl is next nonsense.
Start from simple thinks. 1. maybe Arduino is simpler to learn as idf 2. place into project only lcd init support then touch usw… 3. add LVGL 8.3.x when all works 4.add Squareline generated gui…
OK so the board you are using is not a board that is made by espressif so the code you sent me cannot be used because the code you sent me is ONLY for use with espressif boards. You have a Sunton board.
I can get it to work no worries there. I have to either write or locate a driver for the display that will work with the ESP-IDF… Once that is done you will need to add the new driver to the exported code from Squareline studio.
The issue with how the code export is in Squareline studio is that it is locked to only specific boards. It would be nice if an export could be done without supplying a specific board. So now what needs to be done is the driver needs to be removed form the exported code and a new driver added. I am hoping that the driver isn’t that nested into the LVGL code that is generated. I will dig into it deeper and see what and how things can be done.
I am going to read up on how to add boards to Squarline a little later today. I got some info on it so I will see if it can be done how we ned it to be done that way we can add the correct code needed for your MCU and display.
Adding the board to Squareline Studio worked well, but the code is not compiling. Tried building and it says that it can not locate the file lvgl.h. VSCode shows a few more erros too (most of them are undefined identifier) but i guess they are probably related to not being able to locate lvgl.
Will paste the build output code and a print of my file structure too. And i would totally understand if you can’t help anymore man haha, you already helped a lot.
And i am using esp-idf 5.1 and lvgl 8.3.6 (also tried with lvgl 8.3.10 but it made no difference).
The build output is too long to paste here, so will just paste the errors i saw and upload a file with the full output.
