Hi,
plainly I must realize that the LOCK macros are active in new HAL functions and return "silently " the BUSY state.
In the USART/UART driver there are only one lock flag but the TX and RX functions should work independently from each other. So sometimes a ISR call with for example HAL_UART_Receive_DMA fails with busy because the main thread code was into HAL_UART_Transmit_DMA.
Would be great to split this locks like the UART states in TX and RX!
Best regards
