由于Flash只能写0,因此写入操作实际上是将需要写入的数据与当前Flash中的数据进行位与操作(对于要写入0的位)或者保持不变(对于要写入1的位,但由于Flash不能写1,所以实际上这部分操作是依赖之前的擦除操作将对应位擦除为0后再写入的)。 编程操作的伪代码示例如下: c void FlashWriteWord(uint32_t writeAddr, ...
#define DEV_RAM 0 /* Example: Map Ramdisk to physical drive 0 */ #define DEV_MMC 1 /* Example: Map MMC/SD card to physical drive 1 */ #define DEV_USB 2 /* Example: Map USB MSD to physical drive 2 */ 在对应的几个操作函数里面也有这几个设备对应的操作,但是我们只用一个spi-flash...

It has four Chip Select outputs supporting the following modes: PC Card/ pact Flash, SRAM, PSRAM, NOR and NAND. Functionality overview: ● The three FSMC interrupt lines are ORed in order to be connected to the NVIC ● Write FIFO ● Code execution from external memory except for NAND ...
By default, boot from Flash memory bank 1 is selected. You can choose to boot from Flash memory bank 2 by clearing the BFB2 bit in the user option bytes. When this bit is cleared and the boot pins are in the boot from main Flash memory configuration, the device boots from system ...
Functionality overview: • The three FSMC interrupt lines are ORed in order to be connected to the NVIC • Write FIFO • Code execution from external memory except for NAND Flash and PC Card • The targeted frequency, fCLK, is HCLK/2, so external access is at 36 MHz when HCLK is...
Now we can build the whole project and download it to the flash memory, if everything is OK, the output panel will show:"Verify OK. Flash Load finished at ..." That's the whole process of creating a new project on stm32f103c6. 3. Peripheral Configuration GPIO configuration: ...
