请教一个关于修改eMMC模式的问题

iolML · 发表于 2021-10-18 15:09:13

问题描述：我这块板子有时候可以正常启动，有时候不能。硬件的师傅告诉可能是MMC速率模式不对，让我降低一下频率。目前是52MHz，需要降低到26MHz。在boot里面找了很久关于MMC相关的代码，也尝试修改了很地方，都没办法修改成功，求教MMC修改速率模式的位置。

运行报错：（系统起不来时就一直停在打印的这个位置，进不了系统，这是打印信息的最后一行[ 3.636735] Waiting for root device PARTUUID=c3e88deb-04...）

使用出厂镜像也会出现这个问题吗？

是的，也是卡在这里，不过会出现[ 3.650004] mmc0: error -110 whilst initialising MMC card，所以我才想着修改速率。还有搜索不到这个报错

您用的是那一版出厂镜像啊?用的我们的底板吗？
请将详细的log信息整理成txt文档的格式发一下吧

是出场镜像，底板用的也是你们的

看打印信息烧写的uboot和文件系统都不是我们的出厂镜像啊，先定位问题，建议您烧写一下出厂镜像测试一下，如果用的同一块核心板和底板出厂镜像没有问题的话，那说明您编译的镜像存在一些问题

我问了下，我们是哪类一个开源的uboot和自己做的文件系统烧写进去的，最初是可以用的，后来因为硬件需要限制需要固定速率模式，所以才导致了现在的log结果。那我想请教下，你们的这个型号核心板的速率是自动协商嘛？uboot和内核的速率模式可以固定成一个速率模式嘛？

是根据在设备树里面定义的去适配的，设备树路径：flexbuild/packages/linux/linux/arch/arm64/boot/dts/freescale/fsl-ls1043a-rdb.dts 设备树定义.png

关于这一部分的相关介绍可以看看CPU手册的P1021页，有详细介绍

另外还有个问题，在系统代码里面也有类似自定义配置的文件吗？这些配置是否也需要跟boot里面的相似的配置达成一致？

没有相关的配置文件，
关于第二个问题不是很清楚
