求助：A33主线uboot跑起来了，但是无法从 eMMC 启动

达克罗德 · 2020-01-30 17:53:03

A33开发板买的这一家： https://item.taobao.com/item.htm?spm=a1z09.2.0.0.16a02e8dC4lcxZ&id=589094110822&_u=uc9cub3400
是4GB eMMC， 512MB内存的配置。

uboot直接用的主线最新2020.1版本，defconfig用的是Sinlinx_SinA33_defconfig

生成的u-boot-sunxi-with-spl.bin用sunxi-fel的uboot命令可以跑起来:

sunxi-fel uboot u-boot-sunxi-with-spl.bin

主线uboot驱动很完善，LCD console直接跑起来，而且支持USB Mass Storage 和Gadget等

->mmc list
   mmc@01c0f000: 0 (SD)
   mmc@01c11000: 1 (eMMC)

然后敲入ums命令【需在menuconfig中选上UMS命令】

ums 2 mmc 1

即可把 eMMC 设置成 USB Mass Storage设备（PC上识别为/dev/sdb）

但是接下来把uboot烧到8k地址不起作用，不能启动。我的命令是：

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

没有串口打印，但屏幕也无显示，不过背光能亮起来，感觉还是有什么程序跑起来的样子，只是中断了

这个的默认串口是哪一组，骚到zksw的板子不知道能不能跑，他用的是 spi nor flash

这个默认用的PB2那个串口，我也是搞了好久才搞清楚，在我板子上是uart2
而且spl用的是PF的那个串口0，和uboot不一样。
你的板子得自己试一下了

颜水花生 · 2020-01-30 20:34:38

楼主加油，观望中，今年还打算设计个A33demo板玩玩的，A33性价比太高

居然不支持 A33 spiflash 命令, 失望中.

SPL用的串口和uboot用得不一样。
uboot的dts可以看到：

	uart0_pins_b: uart0@1 {
		pins = "PB0", "PB1";
		function = "uart0";
	};

所以你要查查这个串口
而且uboot里有个选项，可以选TF卡上的那个uart0，你可以试一下

流氓兔 · 2020-02-01 18:42:21

        compatible = "allwinner,sun8i-a33-pinctrl";

                     <GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;

        uart0_pins_b: uart0@1 {
                allwinner,pins = "PB0", "PB1";
                allwinner,function = "uart0";
                allwinner,drive = <SUN4I_PINCTRL_10_MA>;
                allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;
        };

};

arch/arm/dts/sun8i-a33-sinlinx-sina33.dts

&uart0 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart0_pins_b>;
        status = "okay";
};

感谢楼上兄弟回复, 看起来确实是 uart0, 我试一试看会不会改吧.

流氓兔 · 2020-02-01 19:09:13

刚刚核对了 SV50PC核心板硬件使用说明.pdf 手册, 发现我接的就是 PB0/PB1,

这个配置也是uart0:
include/configs/sunxi-common.h

#define CONFIG_CONS_INDEX 1 /* UART0 */

然后我烧到tf卡跑, 也是一模一样问题:

那为什么运行不正常呢?会不会和dram 配置有关系?

这个我知道，你得先去把emmc的boot0下的spl清空，除非你换个新片子，当时浪费了好多时间。（手动滑稽）
还有emmc和nand都可以正常启动的

太谢谢了，emmc确实原来烧过全志的SDK镜像。但我把emmc作为USB Mass Storage Gadget连到PC然后重新分区了，为什么还会有这个现象？这个boot0的SPL在什么位置？

达克罗德 · 2020-02-02 02:46:28

查了一下，boot0似乎就是8KB位置，我的u-boot-sunxi-with-spl也是写的这个位置，难道不会覆盖吗？
https://blog.csdn.net/weixin_43094346/article/details/82563873

一. Boot0 固件更新：(通常boot0 不需要更新)
命令：dd if=boot0_sdcard.fex of=/dev/block/mmcblk0 bs=512 count=S1 seek=S2
备注1: boot0_sdcard.fex 是boot0_sdcard_sun8iw5p1.bin 在pack 命令之后产生
备注2: S1=32K/512 S2= BOOT0_SDMMC_START_ADDR

达克罗德 · 2020-02-02 16:47:52

神奇的发现，无论我覆盖写多少次，甚至重新分区，原来的BSP Linux的boot0，uboot甚至Linux都还在
emmc分区后确实起效了，重启也识别分区正常。但是原来的BSP boot0和uboot为什么还能正常工作呢，太奇怪了

ippen · 2020-02-02 20:32:31

emmc重新分区不会覆盖8K位置的数据，试一下用0将emmc前10M清零，dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=10

问题解决了,把DRAM和CPU频率都降下来:

CONFIG_DRAM_CLK=133

谢谢晕哥以及楼上几位，我终于搞明白了。原来emmc有芯片级的boot，RPMB，GPP，UDA等分区，是正常情况下不可见的（或者选择其中一个）。我们平常访问和创建文件系统的是UDA分区。我板子上默认使能的是boot0分区启动，所以我无论怎么烧写uboot，其实都是烧到UDA分区，下次上电还是从boot0分区启动老的uboot。

解决方法：
打开uboot的CONFIG_SUPPORT_EMMC_BOOT
在uboot设置从UDA（7）启动

mmc partconf 1 0 7 0

现在终于可以正常从emmc启动uboot了

g_dnl_register:failed

的错误，pc上也没有出现U盘符，我用的u-boot版本是2020.04, DTS 用的是Sinlunx_A33_defconfig,

是不是那里还需要特别设定一下，我插入的是板子上的otg USB插口

这个2取决于你的USB口，所以你可以试试其它的口

无论用哪个口 0 ～ 3 都是返回同样的错误：

看上去是usb控制器没有初始化，但是使用 usb tree 命令，又可以列出两个控制器上的设备，应该是已经初始化了的

你的问题我都遇到过，我也试了好久，终于看到另外一个厂家dts是有定义dc1sw，于是我参考定义了一下
&reg_dc1sw {
regulator-always-on;
regulator-name = "vcc-lcd";
};

然后就正常了

楼主你好，我买的根你一样的A33的板子，可是执行ums 2 mmc 1 的时候，出现
g_dnl_register: failed!, error: -6
g_dnl_register:failed
的错误，pc上也没有出现U盘符，我用的u-boot版本是2020.04, DTS 用的是Sinlunx_A33_defconfig,
是不是那里还需要特别设定一下，我插入的是板子上的otg USB插口

你好，请教下，我也是一样的板子，最u-boot-2020.04-rc3，dts也是Sinlunx_A33_defconfig，uboot编译完显示

楼上可能需要换个sunxifei的版本，你是不是用的f1c100的

我好像也是这个

楼主，我按照这个克隆uboot “git clone https://github.com/linux-sunxi/u-boot-sunxi u-boot-sunxi” 编译后可以用sunxi-fel启动正常了
主线uboot，我是直接ftp://ftp.denx.de/pub/u-boot/ 这个网站下面下载 u-boot-2020.04-rc3.tar.bz2，然后步骤是
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make Sinlinx_SinA33_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make
不知道这样编译是不是有问题，还是编译前还需要做什么？

对，我也是这么操作

那就有点奇怪了，按照第一个编译生成的spl可以正常启动，下面的生成的spl用sunxi-fel一运行就超时，总感觉是我哪里弄错了

我的 X3(A33)板子遇到同样尴尬的问题。

从TF卡启动，u-boot和Linux都可以识别和读写eMMC, 就是无法从eMMC启动.

先 mark 慢慢看

根据楼主的帖子提示，然后我在Linux下面如下操作，貌似u-boot有显示了，虽然启动还有点问题。

mmc bootpart enable 7 0 /dev/mmcblk2
dd if=/dev/mmcblk0 of=/dev/mmcblk2 bs=1M count=200

达克罗德说：

谢谢晕哥以及楼上几位，我终于搞明白了。原来emmc有芯片级的boot，RPMB，GPP，UDA等分区，是正常情况下不可见的（或者选择其中一个）。我们平常访问和创建文件系统的是UDA分区。我板子上默认使能的是boot0分区启动，所以我无论怎么烧写uboot，其实都是烧到UDA分区，下次上电还是从boot0分区启动老的uboot。

https://www.cnblogs.com/arnoldlu/p/10762009.html
解决方法：
打开uboot的CONFIG_SUPPORT_EMMC_BOOT
在uboot设置从UDA（7）启动
mmc partconf 1 0 7 0
现在终于可以正常从emmc启动uboot了

我的u-boot v2017.11 没有这个配置，看来要更新代码了: CONFIG_SUPPORT_EMMC_BOOT

然后修改 .config 打开 CONFIG_SUPPORT_EMMC_BOOT 开关.

出现以下错误:

楼主加油，观望中，今年还打算设计个A33demo板玩玩的，A33性价比太高

我的mmc list是
mmc@1c0f000: 0 (SD)
mmc@1c10000: 1
我把uboot烧入emmc中显示

我觉得原因是emmc是1c11000，uboot没有这个设备，自己下了好几个版本的uboot都没有这个设备，然后make menuconfig也没有看到可以改mmc的地方，请问大佬们有没有遇到这种情况，怎么可以解决

你好，你编译的uboot支持ums的可以共享一下吗

你好，uboot在哪里选uart0
