We Have bought STM32F439 Evalution Board from STMicroelectronics. In User manual UM1668 specifies the following in Page No.18 and attached for your reference.
Note: Ethernet works properly in the default setting (which RX_ER is not connected to PI10 of STM32F439NIH6) because PI10 is shared with data signal of SDRAM.
If RX_ER signal is needed, remove R244 and solder R43.
We want to use High speed USB, Ethernet and FMC D[0:31] from the STM32F439NIH6 Microcontroller in Our Application.
Since Some of the Microcontroller pins are shared by both Ethernet and FMC D[0:31] or High-speed USB and Ethernet.
For Example: PI10 - FMC_D31, ETH_MII_RX_ER.
This pin having both Ethernet pin and FMC_D31 pin. There are no other pins having FMC_D31 and
I can see PB10 - ETH_MII_RX_ER, OTG_HS_ULPI_D3.
having same ETH_MII_RX_ER pin, But This pin having OTG_HS_ULPI_D3, there are no pins having OTG_HS_ULPI_D3 to use as High speed USB.
My Queries are as below.
- If I want use High speed USB, Ethernet and FMC D[0:31] without any jumper setting, How can I map the pins of Microcontroller accordingly so that I can use all the Interfaces?
- Can you please share the schematic which will have all three Interfaces without any jumper or resistor setting?
- If not, What will be the solution for the same Microcontroller?
