Ethernet and TFT LCD with an STM32F746IGT6 LQPF176

I want to build a application with a an STM32F746IGT6 LQPF176 with Ethernet and TFT LCD.

I started with CubeMX for checking if this configuration is possible.

When I enable:

- LTDC Display Type: RGB888 (24bits)

- ETH Mode: RMII

in the Pinout view (ETH section) the yellow exclamation mark is displayed with the note:

'Conflict with: LTDC Display type RGB888 (24bits) or/and Only active when TIM2 has an enabled Slave mode with ITR1 as trigger source.'

Does anyone knows what this warning means?

Thanks

Yes, the yellow warning is a ' not all options are available' warning

you can select what you want, if it is white.,

ignore the warning, if you have all your pins.

Hello Theo,

It is possible with STMCubeMX for the pinouts. There is no conflict normally unless you have added more components than just Ethernet and LCD Controller.

As Nick said, There is a conflict and you can not go further with the configuration if yellow exclamation mark is there. To resolve it, just change the pin which supports that function alternately.

Hope this works!
