I found the problem, is is related to the w5500 code.
I didn't explicit set the RST pin to no pin.
There seems to be a default pin which colided with my i2c.
After setting the RST pin explicit to "-1" it's working.

I used a 100R resistor and current meter to tie SDA to ground. I measured 25mA. That means the pin is active driven. I measured all pins of my ESP32-S3 module against SDA. None is connected to it.

Hi

I use an ESP32-S3, I2C and SPi.
IO4: I2C_INT
IO5: SDA
IO6: SCL
IO7: SPI_CS
IO16: SPI_INT
IO11: MOSI
IO12: SCK
IO13: MISO

There is several periphery connected to I2C and a W5500 to SPI.
The order in the code is:
Initialize SPI master
Initialize I2C master
Initialize I2C peripheral

So far, it's ...

Hi

I use an ESP32-S3 board with LCD and GT911 touch. I want to use the light sleep function. The touch IRQ should be used for wakeup.

I use this shortend core, similar to the GPIO example for light sleep:

gpio_config_t config = {
.pin_bit_mask = (1ULL<<GPIO_NUM_4),
.mode = GPIO_MODE_INPUT ...
