STM32F103 built-in bootloader does not respond: how to debug?
I have STM32F103T6Ux. I'm trying to communicate with the built-in bootloader, so we can do software update via UART. I'm setting BOOT0 pin high and it seems the system is in bootloader, since our normal code doesn't come up. I'm setting my side of UA...
Resolved! How can I use UART manually, without HAL_UART_***() functions?
NUCLEO-H723ZG dev. kit.I need take over the full control of the USARTx. I need a TX interrupt and the RX interrupt handled manually independently the HAL_UART_*** functions. The HAL_UART_Receive_IT() and the HAL_UART_Transmit_IT() is useless for me. ...
Use HAL_I2C_Master_Receive_DMA when the receive size is contained in the first received byte?
I'm working with the Nucleo-64 development board with an STM32L476 microcontroller. I wish to receive data over I2C using DMA with the function HAL_I2C_Master_Receive_DMA. However, to use that function I need to specify the parameter Size, and I don'...
Why does the STM32 not start as stand alone, but it starts connected with STM32CubeIDE?
Hi,we work with Nucleo STM32G031K8 board and STM32CubeIDE. The example program Blinky (its full name is GPIO_InfiniteLedToggling_Init) is working as expected. The LED is toggling also with extern power supply instaed of USB power.Now we have programm...
HAL_UART_Transmit sends extra '00' between each byte
This is probably a simple question but I can't find a reason for it - Im using the USART on a stm32L412 and I am sending 3 bytesuint16_t SendDataOn[3]={0x90,0x3C,0x3E}; HAL_UART_Transmit(&huart1,(uint8_t*)SendDataOn,3, 100)Except when I send this, I ...
Resolved! Timer1 doesnt generate an Output while Timer3 does (STM32L552)
I am trying to use the output compare mode of TIMER1 to produce an accurate time course on the PE9 pin. For some reason I don't get an output signal on this pin. Instead, when I use TIMER3 with the same settings as TIMER1, I get an output signal on p...
Hello, I am working with STM32 Nucleo board (NUCLOE-H743ZI2),I have an issue while writing with external debugger stlinkV2. I have connected to microcontroller and able to read the flash memory but I was unable or erase or write into the memory.
I am also attaching the error file from STLINK utility. Can anyone help to sort this thing out.
Don't debug. [ .elf file not found ]
hello everyone,I have the Nucleo F410RB board and I can't debug it. It gives me an error "Error message form debugger back end" and tells me that my .elf file is not found or the directory."F410RB_TEST.elf No such file or directory" The file does exi...
