esp32s3 white screen

Open SzaboPeterBence1 opened this issue 3 months ago • 6 comments

please fix this bug.

i uploaded the code to an esp32s3, but i only get a white/sometimes grey image, sometimes the hourglass appears very incorrectly.

i'm using a 240x320 ili9241 display.

i bought a bunch of parts for this and now it doesn't work.

Here is the debug i got, maybe it helps:

The fact that the display is sometimes corrupted might suggest a bus conflict maybe? It's hard to say what why the sd card init fails with 0x106 otherwise.

You can try enabling debug logging in esp-idf, it should tell you which exact step fails. In your target's sdkconfig find the "Log output" section and replace it with:

CONFIG_LOG_DEFAULT_LEVEL_NONE=n
CONFIG_LOG_DEFAULT_LEVEL_ERROR=n
CONFIG_LOG_DEFAULT_LEVEL_WARN=n
CONFIG_LOG_DEFAULT_LEVEL_INFO=n
CONFIG_LOG_DEFAULT_LEVEL_DEBUG=y
CONFIG_LOG_DEFAULT_LEVEL_VERBOSE=n
CONFIG_LOG_DEFAULT_LEVEL=4
CONFIG_LOG_COLORS=y

You will have to rg_tool.py clean for it to apply. It will also make the binary a lot larger, you might have to rebuild/reflash an entire image for the partition table to be adjusted.

Can you also share your config.h? Maybe you have a problematic gpio or SPI peripheral assignment that would be easy to spot.

I'll try lowering #define RG_SCREEN_SPEED SPI_MASTER_FREQ to 10M to see if that solves it, because it didn't work at higher frequencies either.

I thought if nothing else solves the problem I would try an SDMMC SD card breakout.

SzaboPeterBence1 avatar Oct 02 '25 20:10 SzaboPeterBence1

I'm not anything obviously wrong, you're not using reserved pins and there doesn't seem to be any conflict.

Is the image still distorted when you disconnect the SD Card board entirely?

You could try SDMMC indeed, it might work!

Hello,

Finally I couldn't get it to work with an SPI SD reader, I bought an SDMMC SD reader, but that didn't work either. Finally I made my own SD card reader from an SD adapter, and it works perfectly, even at 40 MHz. I've attached the schematic.
