STM32 MCUs Embedded software

I want to use Threadx for my STM32G474VET processor. I want to know if there are any licensing fees and what are the certifications the RTOS has already met.

I am trying to write a Bootloader on STM32L4R5ZI MCU that gets data through the UART.

My question is I need to send the Application's binary file with CRC using Teraterm/Docklight.. so in the Bootloader project, I need to receive the Hex file of the application and verify the CRC of it, if it matches then it should be written to flash...

STM32G071 and USART ReceiveToIdle problem?

I have project where I use 3 async UART to exchange data between 3 micros.When I use my own FIFO stack with regular USART API everything works.Now I need to use IDLE detection to keep calls to FIFO stack low. Whenever I try HAL_UARTEx_ReceiveToIdle_...

I am using STM32H7 SPI4 with RTOS. when I call errorcode = HAL_SPI_Receive(&hspi4, pbRecv,ulLen,100); I occasionally returns an error The error is OVR and time out. How can you get OVR when polling SPI?
