SAMA5D3 Xplained 开发板烧写官方固件后启动失败【已解决】

一、失败原因：
这块开发板从同事手里接过来时，外部32.768KHz晶体Y2被焊掉了。而原厂的故件程序是需要依赖这颗32.768KHz晶体才能正常启动。

 
二、解决方法
1）将这颗外部32.768KHz晶体焊上后，使用原来的步骤就正常
2）如果保持其不焊接的状态，需要修改bootstrap代码，具体修改方式如下：
step1： 获取代码

git clone git://github.com/linux4sam/at91bootstrap.git

step2：切换分支

$ git branch -r
$ git checkout origin/at91bootstrap-3.x -b at91bootstrap-3.x

step3：生成sama5d3 xplained 的配置文件
$ find board/ -type d | sort | cut -d ‘/‘ -f2
$ find board/sama5d3_xplained -name "*_defconfig" | cut -d ‘/‘ -f3
$ make mrproper
$ make sama5d3_xplainednf_uboot_defconfig

step4：修改配置文件

$ make menuconfig
将对应的32.768KHz oscillator取消，如下图示：

三、回顾失败现象如下
1. 从linux4sam下载demo固件
http://www.at91.com/linux4sam/bin/view/Linux4SAM/GettingStarted
下载如下的 linux4sam-poky-sama5d3_xplained-4.3.zip


解压后，使用demo_linux_nandflash.bat，烧写完成后无法进入文件系统
加载到
ehci_hcd: USB 2.0 ‘Enhanced‘ Host Controller (EHCI) Driver

ehci-atmel: EHCI Atmel driver

就停住了。

 

2. 使用 sam-ba 单步烧写也不成功

具体如下：

1）使用sam-ba 先 “Enable NandFlash” 再"Erase All"、再“Enable OS PMECC parameters”

2）使用 “Send Boot File”将 sama5d3_xplained-bootstrap-nandflashboot-uboot-3.6.1.bin
烧写到0地址处

3）使用“Send File” 将u-boot-sama5d3_xplained-v2013.07-at91-r1.bin
烧写到 0x40000地址处

4）使用 “Send File” 将at91-sama5d3_xplained.dtb
烧写到 0x180000地址处

5）使用 “Send File” 将 zImage-sama5d3_xplained.bin
烧写到 0x200000地址处

6）先 “Enable OS PMECC parameters”，后使用“Send File”将buildroot_2012.11.1- at91_sama5d3_linux4sam_4.2.ubi
烧写到 0x800000地址处

烧写后退出 sam-ba 复位，还是不成功。具体启动日志如下：
