STM32F103VET6 boot problem

Hi,

I want to use PB3 an PB4 pins as SPI1. When i use st-link and debug my code, it works. but when i plug-off st-link it seems that mcu can not boot. I use the codes below for jtag disable , but it does not work. Any advise for my problem?

 

GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB | RCC_APB2Periph_AFIO, ENABLE); // GPIOB & AFIO
/* Configure PB.03 (JTDO) and PB.04 (JTRST) as output push-pull */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_3 | GPIO_Pin_4;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_Init(GPIOB, &GPIO_InitStructure);
GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE);
GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE);
GPIO_PinRemapConfig(GPIO_Remap_SWJ_NoJTRST, ENABLE);

Hi,

I have found the problem. It is about the SPI1 setups, when i try to read some data from SPI, it was blocked in the read function, so i use the code below for start up and it is solved now.

 

RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOD, ENABLE);
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_AFIO, ENABLE);
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB | RCC_APB2Periph_AFIO, ENABLE);
  /*!< SPI_FLASH_SPI Periph clock enable */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);


  /*!< Configure SPI_FLASH_SPI pins: SCK */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_3;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_Init(GPIOB, &GPIO_InitStructure);

  /*!< Configure SPI_FLASH_SPI pins: MISO */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_Init(GPIOB, &GPIO_InitStructure);

  /*!< Configure SPI_FLASH_SPI pins: MOSI */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_Init(GPIOB, &GPIO_InitStructure);

  /*!< Configure SPI_FLASH_SPI_CS_PIN pin: SPI_FLASH Card CS pin */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_3;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOD, &GPIO_InitStructure);

  GPIO_PinRemapConfig(GPIO_Remap_SPI1, ENABLE);
  GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE);

An ST-Link will provide a good reset - so check your hardware reset arrangements...

Use LEDs (or similar) to give "life signs"; eg,

  • Does it reach main() ?
  • Does it get stuck in a hardfault or other error handler ?
  • etc ...

What about Boot pin? how did you connect it? GND or VDD or floating?

You need to connect Boot pin to GND.
