Replace STM32U585 with STM32F407VG on MM6108-EKH05 HaLow Board - Remove Resistors?

General
1

The current board design uses an STM32U585VT6Q microcontroller that communicates with a Wi-Fi HaLow module via SPI.

On the board, the SPI lines are routed through resistor jumpers (0-ohm resistors), which are used to switch or select the communication path.

I have identified these resistors on the SPI lines.

Requirement

If I:

  1. Remove the SPI selection resistors connected to the STM32U585, and

  2. Reconnect the same SPI lines to an STM32F407VG MCU,

Will SPI communication with the Wi-Fi HaLow module work correctly?

You will also want to make sure the RESET, WAKE and BUSY lines are connected to the STM32F4 as well.
