新做的IMX6核心板烧系统设置

新做的IMX6核心板,板上所有芯片使用全新的,在烧系统的时候卡在Loading U-boot这里。新板第一次烧系统是跟已调试好的旧板那样直接烧系统还是需要设置特定的启动程序?需要对EMMC和DDR3做什么相应的设置的吗?

参照恩智浦官方PCB图修改重新制板后,问题已解决,不需要对DDR3和EMMC做任何设置,boot电路和下载以及串口部分电路参照飞凌开发板原理图来设计,便能正常下载系统和正常启动。

Hi youzhen,

One can check u-boot.imx programming it on other media like sd and try

to boot. Then boot to linux and program emmc using commands used by

mfg tools (check ucl2.xml file). Mfg tools can be found on software resources link

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

 

and One can run the DDR stress
