AM335x Beaglebone Black eMMC烧写记录

Hi Sean:

若你也是用bbb或參考其硬體設計, 看你 log, 是開機 mmc 沒有抓取到正確位置, 你可以參考 " BB Black EMMC烧写全记录.pdf"

最後 3.總結和參考文檔, 有說明如何修改 mmc 位置

"

Hi Hank,

    感谢你这么快的回复，已经能从emmc启动，感谢。

你好，

    我有一个疑问，我在U-BOOT里改成默认是从MMC1启动，在插上SD启动卡后是不是就不会从SD卡里启动了，因为我在内核添加的打印信息没有出来，

不是SD卡里的内核镜像文件，但是挂载的文件系统却是SD卡里面的，为什么会这样，有点不明白，希望你能为我答疑解惑

用官网release的debian img从SD烧写到flash（4G）时失败：

UBuntu都可以烧写成功，eMMC应该没坏，也是4G的，可能会是什么原因？

你好：

      请问我用UniFlash 通过USB烧写时一直显示0%不动，而且串口也没有信息输出，这可能是因为什么原因啊？

检查uniflash版本，V3版本，其它的坑爹。另外看下安装目录下的第三方软件，查看opendhcp（好像是）的log文件，里面网络连接方面的情况，如果是通信顺利，会有那些文件，类似uboot servered, rootfs servered...如果没有，表明网络通信根本不通，相应文件没当下来，更别说看串口输出了。

你好：

 我的opendhcp的log如下，能帮我看看是什么问题吗？

而且am335x的UART0接的USB TO UART 也一点东西都没有输出，am335x的UART0需要做什么配置吗？

每次都是到这里就卡住了，这是为什么啊？

貌似pc端没什么问题，相应的文件有送出，只是开发板没有执行。用uart串口看调试信息，如果没有如何输出，只有“CCCCCC...”，基本上就是spl有问题了。按照楼主文档制作spl。或者你试下附件里的spl，直至log文件里挨个顺序有所需文件servered。

开发板上USB-to-serial，一开始不能用，我也没用过。就uart了（用的FTDI232转，淘宝上有），115200，flowcontrol-no。

另外，至于烧写各种文件，完全取决于debrick脚本。如果新添了功能需要kernel支持，flasher的kernel就得重新编译。

我也是自己买的USB-to-serial，直接接在了am3358的uart0上，但是板子上电时，什么都没有输出，连“CCCCCCC”都没有，这是为什么？uart0显示log输出需要特别的配置吗？

我用你给的flasher也试了一下，还是不行，我如果提供的spl的名字不为u-boot-spl-restore.bin uniflash3.0安装目录中third_party/sitara/log/opentftp.log中就会有

[09-Jul-15 13:56:26] Client 192.168.2.3:1234 C:\AM335x_Flashtool\images\u-boot-spl-restore.bin, File not found or No Access

上面这个信息输出，我一改回来log输出就如下了

[09-Jul-15 14:00:38] Client 192.168.2.3:1234 C:\AM335x_Flashtool\images\u-boot-spl-restore.bin, 200 Blocks Served

请问我的tftp服务有没有问题？

文件名是由opendhcp配置文件规定的，从输出上看，dhcp没问题。

串口我买的这个淘宝红色的，先把你的串口搞定。另外就是注意是否还有要求配置网络IP。一共有2次需要配置server IP在windows网络配置下。

串口插上后（ubuntu）会有ttyUSBx出现，minicom配置到那个端口

USB转TTL 支持3.3V 5V双电源 FT232RL Arduino FTDI MWC调试器

在Ubuntu上插上USB to TTL 后有ttyUSB0出现，我将minicom配置到了这个端口，但上电依然没有“CCCCC”，也没有其他的信息。

另外下图中的Device MAC ADDR 和IP ADDR指的是我板子的MAC 和IP 吗？

确定你的串口是否工作，先用sd卡的启动看有信息没，没有，配置你的minicom，直到有正常的输出。

没意外的话，mac和IP是你开发板的资源。

你好， 能将你这边正确的opendhcp, opentftp log日志发一份给我看看么？ 我好对比一下，谢谢。

The log following is waiting for request from board. The attachment is the successful file log.

收到了，非常感谢。 我们的opentftp 到 u-boot-spl-restore.bin, 200 Blocks Served这项就停住了，后面的u-boot-restore.img，uImage，debrick.sh， boot_partition.tar.gz， rootfs_partition.tar.bz2都没有加载上。 

同时串口通信也起不来。

我们检查了下  1  电源管理芯片的供电电压正确。  2 32K 的晶振波形好像不正确。  所以可能是晶振有问题。准备换晶振试试。 

问一下，u-boot-restore.img文件是否和硬件配置强相关？即u-boot-restore.img文件不正确会影响到加载不上去？

All the images are based on BBB. For customized board, you may need ccsv (JTAG) to debug the bare-metal, if the images cannot run on the board.

这可能是什么原因，总是说找不到boot_partition.tar.gz与rootfs_partition.tar.gz，但我确实是把他们与debrick.sh都放在/home/root下的？

To shanshan wan

检查下是不是相对路径和绝对路径的关系。。。

您好，芯片协议4.41选择MMC0还是MMC1呢？

请TI员工更新SDK07或SDK08支持EMMC，我自己试了好多次都没成功，把uboot和rootfs复制到tf卡的2个分区，插入tf卡可以启动，把同样的文件复制到emmc中的2个分区，一直无法启动

eMMC卡启动信息有什么打印失败信息么？

to shanshan wan,

更改下这两个文件的属性为777，另外改为绝对路径试下

要使用emmc，ti的工程师推荐的uboot编译参数是

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_evm am335x_boneblack

以此方式编译出来的uboot，即使在am335x_evm.h中修改了fdtfile和devnum等参数，但是启动时却是默认参数，也就是修改am335x_evm.h文件无效，只有编译时以make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=am335x_evm am335x_evm方式，修改am335x_evm.h文件参数才会有效，请问是什么原因

我们的板子的emmc是4.0的，现在接在mmc1上面。那这个板子是否就肯定不能从emmc启动了？或者说除了上面的方法，是否还有其他方法烧写emmc，让mmc1上面的低于4.4.1的emmc启动。

另外我是用adk08的版本，这种方法还适用么？

AM335x BeagleBone BlackSD卡启动正常，当使用flasher.sh烧写eMMC后（SDK02.00），出现以下信息，请问是什么原因？

当eMMC内有内容后，使用flasher.sh烧写一遍后，不能启动打印CCC，再烧写一遍后，就可以启动了，是需要烧写两遍吗？谢谢！

似乎是机器码不对，uboot跟linux的机器码不对？

我编译uboot跟内核程序的时候都是按照说明来的，

make O=am335x CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm am335x_evm  这个是编译uboot的

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage dtbs  这个是编译kernel的

在tftp的根目录下，我放了如下几个文件，之前我只放前面三个文件，但是不能用，都放上之后，能够有27%的进度了，但是仍然不行。

debrick.sh

boot_partition.tar.gz

rootfs_partition.tar.gz

u-boot.img

u-boot-restore.img

u-boot-spl-restore.bin

uImage

请问下，我用的是V3.4.1.00012，这个版本可以吗？我的dhcp和tftp的log情况如下

还有我的uniflash默认配置入下，点击start flashing，下面的状态栏什么都没有，串口输出信息为正常的启动，应该是完全没有从Windows目录load什么东西

你好我把移植好的andriod4.2的内核烧写到了eMMC中，启动安卓的时候发现了如下的错误，并且系统启动不起来了。请问下，这个问题如何解决，

当前的内核在SD卡中是可以正确启动的。

你好，我的情况和你一样，请问你解决了吗？能否分享下如何解决的。谢谢了

您好，我现在参照beaglbone black的外围自己做了一块板，emmc接在emmc1上，根据您的文章，是说的使用USB进行TFTP传送文件，我现在使用以太网口进行传送，前面几个和usb传输的patch我就不用打了？包括后面kernel对USB 对RNDIS等都不需要配置？

另外，我使用以太网口需不需要额外修改什么？生存u-boot.img和u-boot-spl.bin时，我需要使用什么配置文件？

我使用的sdk版本不是6.0，是ti-processor-sdk-linux-am335x-evm-02.00.02.11-Linux-x86-Install.bin。

我参考了很多文章，包括ti的教程，都没有效果，可能我使用的SDK版本较新，很多地方有出入。我也是第一次搞这玩意，麻烦您能否详细解答下。谢谢。。。

 Jian Zhou,你看我这是什么问题啊，

    你好，我是要用BBB这块核心板，但是产品于要做成通过USB接口更新固件的方式。感觉这篇文章写的应该正好可以解决我的问题，但是我不会Linux,按照网上的教程，总算是把Linux和SDK装起来了，但是还是没有编译成功。

    所以想问一下，网上有没编译好的文件呀，就是教程里面用到的这些，我的理解是烧写用的SPL,u-boot,linux uimage,还有要烧写的spl,u-boot,uimage,文件系统。

如果能找到这些的话，我是不是就可以不用自己编译了？

windows环境下使用，好像两个网卡不能设置成同一个IP地址，请问这种情况怎么处理呀？

谢谢

hi 请问你这个问题解决了吗？ 现在我也遇见和你一样的问题，求教一下

目前还没有！继续研究并等待答案！

 @ rubin Li 请问你的问题解决了吗？

M3350_EV_BOARD 评估板

M3352-N128LI V2.04 核心板

使用am335x-evm-linux-sdk-src-03.00.00.04.tar 源码

我的报以下error 

Error: unrecognized/unsupported machine ID (r1 = 0x00000e05).

Available machine support:

ID (hex) NAME
ffffffff Generic DT based system
ffffffff Generic AM33XX (Flattened Device Tree)

请问您要什么文件，我之前已经把我做的一些文件贴上去了。

哦，谢谢！

我是说烧写用的这些文件，

烧写用的mlo,u-boot,uimage

要烧写到板子上的boot_partition.tar.gz，rootfs_partition.tar.gz

还有脚本：debrick.sh

有些我在楼上找到了，有些我自己也编译好了，但是感觉，对我一个没有入门的人来说，自己编译这些，比较麻烦，而且一出错，就不知道是自己编译错了，还是下载错了，也不知道是u-boot编译错了，还是内核编译错了。

要是能给我一个可以直接在BBB中国版开发板eMMC里运行的u-boot和内核那就非常感谢了。

我现在的是uboot启动起来，但是没有加载内核，不知道什么原因。

烧写用的相关文件我已经在这个帖子的第一页附上去了，你看一下。

您好，

请问是这个吗？

这个是就是要烧写到eMMC里面的吧？

这个是烧写用的MLO和U-boot。

烧写到BBB eMMC的image，用SDK里的就可以了

好的，我再试试，谢谢了。

现在等于说烧写用的SPL，u-boot，脚本都有了。

emmc启动用的从SDK    prebuilt-images 里也找到了。

现在只有烧写用的uimage是我自己编译的了。
