dm8168 NAND FLASH固化完u-boot，串口打印？？？？？？？？这是怎么回事？

Zhang Xiaobing，

用SD卡可以正常启动么？

板子有仿真器可以连上么？如果可以，请参考：http://processors.wiki.ti.com/index.php/Debug_Tips_for_DM81xx_Boot_Fail

板子没有SD卡，只有NAND,以太网口，串口，我通过CCS 仿真器使用提供的 nand-flash-writer.out 加载U-BOOT.  请问，U-BOOT烧写到NAND FLASH ,再次烧写时会重新从第一个block烧写，该怎样烧写U-BOOT,怎么设置NAND FLASH的烧写地址地址以及读NAND Flash地址？

Zhang Xiaobing，

我提供的链接提到的查看寄存器的方法，你是否有尝试。

关于uboot烧写uboot，请参考：http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide#TI816X_3。

首先，谢谢您的回复

这是从TRM文档中截取的，请问如何用CCS查看这些地址的寄存器？

CCS->View->Memory Browser

谢谢，写NAND的命令

I8168_EVM# nand write <addr> <offset> <len> 

都是基于EVM板的，启动后在板子的终端上执行的，

我连接板子只有仿真器能执行这样的命令吗？  只有仿真器如何设置这些参数？

Zhang Xiaobing，

请参考：http://processors.wiki.ti.com/index.php/DM816x_AM389x_PSP_Flashing_Tools_Guide#Burning_images_to_NAND_Flash_.28using_CCS.29。

感谢您的回复：

这是我从寄存器读出的

  R0=0X00000004

R14=0X40307748

  R1=0X00000808

 R9=0X4031CFF4

R5=0X00028078

R12=0X40306D9B

R7=0X4031CD7C

能从这些值看出什么？

这是我在固化时的console打印，并没有出现设置偏移地址的选项，请问在哪能下载到设置偏移地址的nand-flash-writer.out 文件

Zhang Xiaobing，

你使用的nand write out文件是下面链接的最新的psp里面的么？

http://processors.wiki.ti.com/index.php/TI81XX_Linux_PSP_Releases

感谢您的回复，可以用仿真器对不同地址进行NAND_flash烧写了。

但是例如“#fw_setenv bootdelay 3;fw_setenv gatewayip 192.168.1.1;fw_setenv netmask 255.255.255.0;fw_setenv ipaddr 192.168.1.8;fw_setenv serverip 192.168.3.21”

“fw_setenv bootcmd 'nboot 0x81000000 nand0 0x580000;bootm 0x81000000”

“fw_setenv bootargs 'mem=128M console=ttyO0,115200n8 ubi.mtd=4,2048 root=ubi0:rootfs rootwait=1 rootfstype=ubifs rw ip=192.168.1.8:192.168.3.21:192.168.1.1:255.255.255.0::eth0:off vram=20M notifyk.vpssm3_sva=0xBEE00000'”

这样的配置命令应该怎样通过仿真器写入到板子上呢？

Zhang Xiaobing,

你发的这些配置，看起来都是uboot的设置，可以在uboot运行起来后，在uboot里面设置。

 chris,谢谢您的回复。

  1、我固化完uboot到NAND后，掉电后，串口波特率设置为57600，打印信息为 ？   ？   ？  ？，是uboot并没有固化成功？请问波特率应该怎么设置?

   2、uboot固化完成后，要设置外设的配置参数，saveenv 如何配置到板子，如果串口调通，能否通过串口配置，还是仿真器？  主要是想知道网口和串口怎样配置，实现与板卡交互。

我在下面帖子里有分析过类似的trace信息，你能参考分析一下你的情况么？

Chris,    请问， TI8168 evm板原理图在哪可以下载？

DM8168：

http://processors.wiki.ti.com/index.php/DM816x_Resource_Guide(English中文)

 关于dm8168的27M时钟输入，我看evm板是这样的，

我们的板子是这样的

在C19脚直接接地，一个CDCV304的片子外供的时钟，请问这样可以吗？

Chris,

我在使用gel进行Scripts 测试时，出现如下错误:

这是什么原因引起的?

Zhang Xiaobing,

请尝试降低JTAG的速度，看看是否有改善？
