定义 设备
struct FlashDevice const FlashDevice = {
FLASH_DRV_VERS, // Driver Version, do not modify!
"New Device 256kB Flash", // Device Name
ONCHIP, // Device Type
0x00000000, // Device Start Address
0x00040000, // Device Size in Bytes (256kB)
1024, // Programming Page Size
0, // Reserved, must be 0
0xFF, // Initial Content of Erased Memory
100, // Program Page Timeout 100 mSec
3000, // Erase Sector Timeout 3000 mSec
// Specify Size and Address of Sectors
0x002000, 0x000000, // Sector Size 8kB (8 Sectors)
0x010000, 0x010000, // Sector Size 64kB (2 Sectors)
0x002000, 0x030000, // Sector Size 8kB (8 Sectors)
SECTOR_END
};
根据芯片手册 编写对应代码
