Compile error with esp32-C3

[yeyf2023]

I used the following command to compile the firmware for ESP32 - C3, but after an error was prompted, the compilation could no longer proceed.

python3 make.py --optimize-size --flash-size=4 esp32 BOARD=ESP32_GENERIC_C3 DISPLAY=st7789

Error:

I just pushed a commit that should fix the problem.

[kdschlosser]

also, your build command is incorrect

it should be

python3 make.py esp32 BOARD=ESP32_GENERIC_C3  --optimize-size --flash-size=4 DISPLAY=st7789 

with 4mb of flash space I really suggest not using --optimize-size as this is going to really slow things down when it's running. The firmware should only be 2.5mb in size so you have more than enough space. The C3 only has a single core so you want to keep the optimization for performance.

Thanks for updates and tips.
I have compiled it successfully, and I am now preparing for the LVGL test.

In addition
I encountered the following problem when testing LVGL after ESP32-S3 was successfully compiled, and it cannot be displayed

A fatal error occurred. The crash dump printed below may be used to help
determine what caused it. If you are not already running the most recent
version of MicroPython, consider upgrading. New versions often fix bugs.

we are going to let the display driver sort out the best freame buffer size and where to allocate it to.

fb1 = display_bus.allocate_framebuffer(_BUFFER_SIZE, lcd_bus.MEMORY_INTERNAL | lcd_bus.MEMORY_DMA)

[kdschlosser]

you don't have a _BUFFER_SIZE constant

[kdschlosser]

it would also be helpful if you would decode the backtrace from the error. You can look up how to do it by doing a good search for "ESP32 decode backtrace"

The firmware you are running is also for an ESP32 S3 and not an ESP32 C3.

[kdschlosser]

OK sorry about the S3 comment. I didn't realize that was a different MCU.

I am going to need to know more information, if you can provide me a link to the data sheet for the board that would be very helpful.

I also need to know the exact build command you are using.

[yeyf2023]

This is my data sheet using the MCU ESP32 S3 N16R8

esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf

My build command
python3 make.py esp32 clean BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT --flash-size=16 DISPLAY=st7789

[kdschlosser]

are you sure that you have the WROOM-1 and not the WROOM-2? The WROOM-2 has octal SPIRAM and also octal FLASH.. You can try adding --octal-flash to your build command.

[kdschlosser]

give this a try for your script..

I used the code above, but it still doesn't display with a hard reset.

Here is a picture of the ESP32S3

[kdschlosser]

I think you have gotten a counterfeit ESP32. Espressif has their name etched into the chip with their logo. I am not seeing that on yours. This has happened to me with ones I bought from Amazon.

[yeyf2023]

Thanks for tips. I will investigate.
Yesterday, I tested the 135 * 240 st7789 LCD with this S3 MCU, and it was able to display, but there were still some issues.
It also has something to do with LCD.

[tetopik]

I used the code above, but it still doesn't display with a hard reset.

Here is a picture of the ESP32S3

I'm actually own those lcd, it requires the spi polarity to be reversed.

display_bus = lcd_bus.SPIBus(
    spi_bus=spi_bus,
    spi_mode=2, # phase | (polarity<<1)
    freq=_LCD_FREQ,
    dc=_DC,
    cs=_LCD_CS,
)

[kdschlosser]

and there is the answer. use spi_mode=2

[yeyf2023]

Thanks for the tip.
I noticed that the LCD does not have a CS pin, and the setting when not using LVGL, which has been resolved.
but i used spi_mode=3. phase=1 polarity=1
