Why can't SPI0i be enabled?

Why can't SPI0i be enabled? [Copy link]

    I used the manufacturer's SPI example to test, but the program could not run. After checking line by line, I found that the program paused when it reached SPI0_enable. I could run past this line in the debugger in KEIL5, but it could not run past this line when downloaded to the board. Could you please tell me what the problem is? Program code: #include "gd32f3x0.h" #include "gd32f3x0_it.h" #include "GD32-Colibri-F350Rx.h" #define arraysize 10 uint32_t send_n = 0, receive_n = 0; uint8_t spi0_send_array[arraysize] = {0xA1, 0xA2, 0xA 3, 0xA4, 0xA5, 0xA6, 0xA7, 0xA8, 0xA9, 0xAA }; uint8_t spi1_receive_array[arraysize]; ErrStatus memory_compare(uint8_t* src, uint8_t* dst, uint8_t length); void rcu_config(void); void gpio_config(void ); void spi_config(void); /*! \brief main function \param[in] none \param[out] none \retval none */ int main(void) { /* init led1 */ gd_eval_led_init (LED1); /* NVIC config */ nvic_priority_group_set(NVIC_PRIGROUP_PRE1_SUB3); nvic_irq_enable(SPI0_IRQn ,1,1); nvic_irq_enable(SPI1_IRQn,0,1); /* peripheral clock enable peripheral clock enable*/ rcu_config(); /* GPIO config */ gpio_config(); /* SPI config */ spi_config(); /* SPI int enable enable interrupt */ spi_i2s_interrupt_enable(SPI0, SPI_I2S_INT_TBE); spi_i2s_interrupt_enable(SPI1, SPI_I2S_INT_RBNE); /* SPI enable */ spi_enable(SPI1); spi_enable(SPI0); //Execution pause statement.

    I am going to use SPI1 to receive data. I am going to receive an 8-byte string about once a minute, but I don't know how to write the receiving code. I would appreciate your help. In addition, when I tested the serial communication, I also don't know how to receive the string sent by the computer serial assistant.

Have you read the interrupt file gd32f3x0_it.c?

Thanks for the tip! I just opened the file and read it. Do I need to first determine what kind of exception it is and then analyze and deal with it?
