板子不启动，无打印信息

szkalwa

楼主请参考下我以前做海思DVR产品时，UBOOT或UART起不来的原因：
" c0 K5 x' Q: Z1、DDR芯片是否在软件支持范围内？型号太多，有的软件可能还要调整对DDR的支持;或DDR芯片没有焊好；
# l: K6 j" a# J# B) S2 P2、NAND FLASH品牌有的支持有的不支持，搞得无法启动！
8 L% j8 t6 @3 R# pARM的BGA芯片连接NAND这一块，BGA 引脚有虚焊导致；
3、复位芯片有问题
1 q# ?' G) b6 c) T! X9 S% z4、再有就是网络芯片后缀型号不一样，也会导致无法启动（这一点有些纳闷，一直想不明白，这刚启动怎么会和网络挂上关系？）
% Q  E/ J8 ]3 |- g- ?# W0 T8 R5、电源；（这个相对好解决，量一量就知道）
6、最后就是PCB设计问题了，但如果DDR3不那么完整性，也不至于会不启动，顶多是能启动了，但一会就会死机的

klend

會不會是DDR的時鐘匹配電阻有問題？是差分100歐阻抗控制的。這裏兩個電阻是100歐。

换了nandflash后和加焊DDR后有两种状态，但是板子都没有启动成功，串口有打印。
以下是状态1的log:

+ X5 Q. I/ H/ R' V3 k& b9 t是pcb布线影响到DDR的频录跑不高还是DDR的时序有问题？怎么确认呢？怎么解决？

抓个妞去溜溜

根据经验，如果一切电气特性正常没有打印，那么接下来就是CUP和Flash的问题了（当然要先确定软件是否烧对）。如果有打印信息后就要看DDR有没有跑起来，DDR有没有跑起来可以看打印信息，这方面可以询问厂商DDR没有起来的经典打印信息，如果涉及到kernel的问题，这就需要软件配合了，现在即使同一型号的CPU可能因为版本不同就会导致kernel问题。

是没焊，IC温度很高，焊了以后温度稍低一点，但是还是不能启动成功。
