Description
Hi,
With recent Olimex image for STMP1 respectively
We observed that an I2C device is missing (with previous image release it was working fine). See details below
root@oi-coupler-new:~# i2cdetect -l #not working image STM32MP1-OLinuXino-LIME-bullseye-base-20240312-135508
i2c-1 i2c STM32F7 I2C(0x5c002000) I2C adapter
i2c-0 i2c STM32F7 I2C(0x40012000) I2C adapter
# working I2C
root@stm32mp1-4:~# i2cdetect -l
i2c-1 i2c STM32F7 I2C(0x40013000) I2C adapter <!--Missing !
i2c-2 i2c STM32F7 I2C(0x5c002000) I2C adapter
i2c-0 i2c STM32F7 I2C(0x40012000) I2C adapter
So it looks like that STM32F7 I2C(0x40013000) is missing.
The steps I did to setup this device are described here (described in part of the rPLC coupler docs)

Research direction
Start by comparing the 20240312-135508 image with the previously working image and follow the rPLC coupler OS setup instructions. Use i2cdetect -l on STM32MP1-OLinuXino-LIME to investigate why the STM32F7 I2C adapter at 0x40013000 is absent; done means that adapter is listed again in the recent image.
