CRC C查表法实现（待完善）CRC-8CRC-8static const uint8_t crc_table[] = { 0x00, 0x07, 0x0e, 0x09, 0x1c, 0x1b, 0x12, 0x15, 0x38, 0x3f, 0x36, 0x31, 0x24, 0x23, 0x2a, 0x2d, 0x70, 0x77, 0x7e, 0x79, 0x6c, 0x6b, 0x62, 0x65, 0x48, 0x4f, 0x46, 0x41, 0x54, 0x53, 0x5a, 0x5

遇到了一个坑,顺便就梳理了下ARM单片机的启动流程.简单的介绍开发环境:目标板:STM32F412xx. 512K的FLASH(0x08000000,0x080080000)和256K的RAM(0x02000000,0x020040000)开发环境:keil + JTAG应用具有升级功能,存在两个固件BL(bootloader),AP(application).空间分配BL使用的空间是(0x08000000,0x08040000),分了256K,因为我的BL中放了很多的字符和图片
