大家好，
我使用的是imx6solo芯片，BSP版本为官方L4.1.15，目前公司做了一块开发板，DDR已经通过stress tool工具校验ok了，但是目前从SD卡启动，uboot没有任何打印信息，拨码开关已经拨到SD卡启动，开机也测量到SD卡的读写时钟信号，仔细核对了串口配置也没有问题，请教各位大神给予指导，感激不尽！
Which NXP board is your reference design?
What is the different between your board and NXP board?
Which UART you used for debug port on your board?
Is your hyper terminal setting correct? (115200, 8N1, No flow control).
thank you very much，i have solved the problem
