any suggestion? Did you thing this is an error related with display driver or an issue with compile environment ?

[kdschlosser]

I am not even sure how you managed to get it to compile. The macOS build CI is currently failing. I believe I just fixed it. The CI is running now so I will know in about 15 minutes.

I will compile a binary for you in a bit. you can flash that binary and see if it works. If it does then we know it's the environment that is causing a hiccup.

[kdschlosser]

what build command are you using?

How much flash does your board have? How much ram does it have?

[marilantagliari]

what build command are you using?

How much flash does your board have? How much ram does it have?

Command: make -C ports/esp32 BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT DISPLAY=st7796 INDEV=gt911

LCD module uses ESP32-S3-WROOM-1, 512KB SRAM, 384KB ROM, 8M PSRAM,Flash size is 16MB

[kdschlosser]

AHhhh and there is the issue. your entire build command is wrong...

it should be...

python3 make.py esp32 clean mpy_cross submodules BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT DISPLAY=st7796 INDEV=gt911 --flash-size=16 --oct-flash

You may or may not need the --oct-flash. you would have to look of the exact model number of the ESP32 you are using, specifically the numbers/letters after the -. I believe there are 2 versions of the 16mb of flash, one that is quad and one that is octal. I have not seen the quad variant at all so chances are you have an octal. The ESP32 is able to auto detect the ram size but not the flash size so this needs to be set at build time.

we can also give your setup a significant speed boost as well. We can chat about that later once we get things going for ya.

Thanks a lot Kevin, but still getting error.. sorry for the wrong command, but your command has a param --octal-flash, in my case is quad, I flashed with octal param and got error rebooting the esp32..

In my case the LCD is a RGB 3wires (ST7701), and I've been trying to use your drive RGB_DISPLAY.py, maybe this error is causing by wrong driver?

the error got in esp32:

[kdschlosser]

at least we know you are not using the correct flash size. as I said you may or may not need the --oct-flash in the build command. Your MCU is the first I have seen that is not octal.

what code are you running when the ESP32 boots?

[Carglglz]

@marilantagliari You need to setup the display with lv.display_create + flush callback + buffers before creating any lvgl object.

e.g. this happens in unix port too:

MicroPython v1.24.0-preview.111.g2046793aca.dirty on 2024-07-11; darwin [GCC 4.2.1] version
Type "help()" for more information.

the compilation and flash is working fine... thanks Kevin. My problem now is the drive for my st7701, I'm not able to write this driver but I've been learning about this.

Thanks Carglglz, is true... after lv.display_create works fine... but I'm trying the example written by Kevin and got error in allocate memory framebuffer.... but I still need a right driver for LCD ST7701 spi rgb.. :-(

[kdschlosser]

The ST7701 display is an RGB Bus display and as such you need to allocate 2 frame buffers to SPIRAM in order for it to work. Unless the display you are using is incredibly small.

[kdschlosser]

this is also conflicting..,..

_BUFFER_SIZE = const(25600)
fb2 = display_bus.allocate_framebuffer(_BUFFER_SIZE, lcd_bus.MEMORY_INTERNAL | lcd_bus.MEMORY_DMA)

Traceback (most recent call last):
File "", line 61, in
File "display_driver_framework.py", line 169, in init
MemoryError: memory allocation failed, allocating 2971407374 bytes

The error is saying it is happening in the display driver but the code says that you are doing it yourself and the display driver is not handling the buffer creation.
