Is it possible to operate USB-C (CN15) and Mini-PCIE (CN13) on the STM32MP257F-EV1 board with end devices at the same time? For example: A USB-C 4 port hub is connected to the USB-C port and a WLAN card is connected to the PCIE port.
The documentation says that this is not possible at the SAME time. I understand that because it is a combophy.
In the figure MSv67526V2 on the page https://wiki.stmicroelectronics.cn/stm32mpu/wiki/COMBOPHY_internal_peripheral there is the Mode_sel pin which is probably for activating the two modes. So it should be possible to activate the corresponding mod with the software.
If so, this is also supported in the Linux kernel.
Thanks for an answer.
