Hello,
I am trying to configure SPI Slave on STM32F4xx in the Laird EWB Platform. The Host MCU is STM32F412.
I have added SPI4 on the STM32 to the Wiced definitions in platform.c. I can use this as SPI master without issues.
When I use the Wiced SPI Slave functions, I am getting a build errors.
build/laird.ampnet_app-LAIRD_EWB-ThreadX-NetX-SDIO/libraries/STM32F4xx.a(wiced_platform_common.o): In function `wiced_spi_slave_init':
C:\Data\AMP_WORK\WICED-Studio-6.6\43xxx_Wi-Fi/WICED/platform/MCU/STM32F4xx/../wiced_platform_common.c:429: undefined reference to `platform_spi_slave_drivers'
collect2.exe: error: ld returned 1 exit status
Another developer had the same issue some years ago. Here is a link to that thread.
SPI SLAVE
The Laird EWB platform has platform_spi_slave_init(...) in the platform file.
...WICED\platform\MCU\STM32F4xx\peripherals\platform_spi.c
This same source file has the functions I used for SPI master.
What step am I missing to use this source for SPI slave?
Thank you,
-Rocko
