HiI want to use a program i made before with the new IDE 1.8. It should reveive som data with the UART2 until EOL is received. It works on time and after it throws an interrupt (loops in the void USART2_IRQHandler(void)) but doesn't call the HAL_UART...

Posted on April 19, 2013 at 18:11Hi, for an automatic test, i need to Halt and Run a STM32. It works without problems with the STM32 ST-LINK Utility, but not (program is still running) when I use the CLI (st-link_cli.exe) in this way:st-link_cli.e...

Ok - i found the problem.It was a memory location fail (initalize more then the size)- and this resets the UART Setings (it occures after the first receive) an after this my UART->Init was 0 - and maybe other flags too.Now i know all the uart bit's ...

Hi TDKthe HAL_OK comes with 0 (without breakpoint in the interrupt-Routine)But my problem is, that the HAL_UART_RxCpltCallback in my Main is only called one time. After this the Receive- Interrupt is reconized, but the callback is never called again....

I tried it without debugger too, but its the same effect.It looks like an unknown UART interrupt is thrown all the time.I tried the Release Version, it hangs in the same way.Is this part of my Callback ok? __HAL_UART_ENABLE_IT(&huart2, UART_IT_RXN...

Hi Janwhen it works correct the firts time i get an error- but i think its because of the breakpoint (UART_Error_Callback is called). The Registers look like this:SR = 0xf8CR1 = 0x212cCR3 = 0x1In the next run no error ocures when the HAL_UART_IRQHand...

Hi TDKit's working fine. I receive the first Byte with interrupt, then i poll the next "single" bytes until a CR or LF arrives. RxBuffer[i]= toupper(Rx_data[0]); adds the last byte in loop.This is not the problem 
