Seeed SOM – STM32MP157C connector pin numbering


I am bit confused regarding the DF40 connector pin numbering of the SoM.

Let us take the BOOT1 signal as example.

On the page of the SoM it says that BOOT1 is pin 7.

In the schematic of the eval board it says pin 8.

The pins all seem mirrored and I want to make sure not to end up with a dead PCB. Which one is right or am I interpreting the info incorrectly?
