有时不能启动

[Lts52341314]

有20%的慨率不能启动，都是卡在uboot，提高日志等级后查看打印，基本上是频烦打印[01.505]logical area info: 468 258048 last_lba: 235871时停了

[YterAA]

有没有尝试更换一下 SPI NAND 储存器，可能是储存器坏块了

[Lts52341314]

@yteraa 试过，和demo板上的交换试过，在demo板上始终是好的，在我的板子上就会有问题

[YterAA]

@lts52341314 芯片换一下看看，如果还有问题那可能是板子设计问题了

[whycan]

@lts52341314
遇事不决，先查电源．

[Lts52341314]

@whycan 电压看过和demo板一样，会是电源不稳定吗

[whycan]

@lts52341314
注意电源波纹，以及峰值电流下电压会不会被拉低。

[Lts52341314]

@whycan VCC-IO有一点锯齿，正常吗

[whycan]

① 电源旁边并一个 大电容 + 0.01uF小电容
② 降低SPI 速率到 5Mhz左右

先酱紫试一试

[Lts52341314]

@whycan 试了加滤波电容，没有好，不过在DC-DC的反馈电阻上并一个小电容好了，现在不能启动的概率变低了
