Hi every body.I have a project based on CMSIS-RTOS2 and STM32F107VC.There are threads for 2 USARTs,TCPNET and GPIOs all working fine. Also there is a thread to drive a spi memory on SPI3.When I use HAL libraries to drive the spi, it dosen't worke while TCPNET is active(initialized).When I use CMSIS_SPI_DRIVER (instead of HAL) it dosen't work at all(even if all other threads not started).ARM KEIL version : 5.30CMSIS driver version : 2.6.0CMSIS version : 5.7.0Network Component Version : 7.13.1SPI API : 2.3.0USART API : 2.4.0I prefer to use cmsis spi driver and expect it to work as well as the cmsis usart driver instances.Reply will be appreciated.Regards
