android 跑死掉

你用的android的版本是哪个？硬件平台？（是在TI的EVM板上面进行测试的吗？）

android是ti官网上的：TI_Android_JB_4.2.2_DevKit_4.1.1。硬件平台是用am3354自己做的板子, ddr3:MT41J128M16JT-125, 电源：TPS65910A3，nand:MT29F2G08

只是单纯的跑android系统就会死吗？还是跑了你写了测试应用之类的东西？

自己做的板子的话，需要排查的因素有很多的，硬件方面，会不会是DDR不稳定带来的问题：ddr3的配置是否正确，有没有做过software leveling？软件上做移植的时候，因为肯定要去掉EEPROM做配置，是否会在配置的时候，有些没有正确配置，或者修改误删了某些必要的配置。

steven 谢谢！

1. 我使用的DDR3的配制，你们有做过吗？有的话，能否发一个给我？

2. 什么叫software leveling? 要怎么做？

3. EEPROM配置，我现在是写的死到程序里的。不用配置了。

1. 这个配置有些是根据自己的layout参数得来的，除非照抄原版，layout都一样，配置才可能一样。否则，一定是要自己配置的。

2. 对于DDR3的配置，我们是要求一定要做software leveling的，关于这部分内容你可以参考这两个帖子，里面讲述的比较详细：

http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/17684.aspx

http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/30143.aspx

3. 是的，我的意思是说，EEPROM上面存储的板子不同ID信息，其对应的是不同的硬件相关的配置信息：有的有nand配置，有的没有；有的是DDR2的配置，有的则是DDR3的配置。你写死了之后，要注意当前使用的配置信息，和你硬件板上面的资源是对应的才可以。

最好也能查下你的pmic的具体型号，包括小版本号，正确的可以参考 http://www.ti.com/lit/ug/swcu093c/swcu093c.pdf, 最好确认下你的pmic是否正确

你好，根据您提供的两个文件，我分别下载并阅读了这两个文档，不过，个人觉得这个两个文档描述的太过简单，因而还有几个地方不是很懂：

1、文档中说，先根据板子上的CK和DQS实际的走线长度，计算出Seed Values。这个基本了解，目前我们使用的DDR3为DDR3-1600（11-11-11），主频是不是就填1600MHZ？根据实际走线，求出平均长度DDR_CK trace=1.005，DDR_DQSx trace=0.8844。这样可以自行算出WR DQS_SLAVE_RATIO=88，RD DQS_SLAVE_RATIO=40，FIFO_WE_SLAVE_RATIO=18C。

2、SW Leveling的第二步Load DDR3_slave_ratio_search_auto.out and run the code，这个有点突兀，没有前因后果，不知道文件DDR3_slave_ratio_search_auto.out是指哪里的文件，里面内容是什么？run the code更加不知道在说什么，在什么软件环境下，用哪个软件运行哪个代码？后面也没有详细交代。

3、再后面出来了Optimum Value，这个信息是串口打印信息么？这些信息如何出来的？获得的这些优化值，最后要用到什么地方，去修改哪些文件的配置定义？

4、目前我们系统有两种，一种是单纯的LINUX系统，一种是android系统。针对这两个系统，在做SW LEVELing以后，需要修改哪些文件和配置？

5、在uboot下，用mtest测试时，一直可以看到pattern 0000XXXX Writing...   Reading...，是不是代表测试DDR3内存OK？

秦工：我们用的PMIC是tps65910 A31A1 

我给了您一个连接，可以一起参考下，这个片子是OK的

关于您的问题，回答如下：

1. 这里的主频是指您所需要DDR3跑的主频，AM335x最高支持到400MHz，所以最多可以设置为400MHz.

2. 关于这个software leveling 的工具，具体情况可以参考

     http://processors.wiki.ti.com/index.php/AM335x_DDR_PHY_register_configuration_for_DDR3_using_Software_Leveling

      http://processors.wiki.ti.com/index.php/AM335x_EMIF_Configuration_tips

    以上两个是原始的说明，下面我的同事给出的是更本地化的说明。

    如果您没有jtag工具，也可以参考http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/53263.aspx 中的MLO工具，可以在sd卡上运行，从而跑下software leveling.

3. 如果您根据工具跑出来的值，就是用于配置DDR的寄存器的值，可以根据两个deyisupprt的文档，写到uboot中去，这个需要贵司的软件工程师帮忙。

4. 同第三点，您可以参考 http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/30143.aspx中pdf文档的第4页。

5. ddr的稳定性，最好能把系统跑起来后压力测试才能最终确定，目前您所反馈的问题来看，很可能是ddr稳定性的问题。

秦工，Steven:

        谢谢你们的大力支持。

        DDR3做了leveling后，运行有很大改进。运行时间可以持续20分钟（以前是一开机，android起动后，就死机了）。

        现在运行中出现如下log, :

你的DDR software leveling已经通过了是吧？有把算出的优化值设置为最终的配置参数吗？做一些读写测试能过吗？比如不停的申请内存空间，读写再释放？

从你上面给的log信息来看，都和3D Graphic加速模块相关，我之前遇到过一个类似的case，主要原因是在VDD_CORE的电压供电上（VDD_CORE就是给3D Graphic模块供电的电源轨）：因为layout的问题，导致电压线损比较高，从而使得进入到AM335x芯片端的VDD_CORE这一路的电压会有低于spec标准的情况出现。最后通过略微提升VDD_CORE对应的出PMIC侧电压，就把这个问题解决了。你可以尝试改动一下TPS65217的相关电压设置，提升一点VDD_CORE的电压测试一下看结果。

Steven:

        请问能正常工作的CORE VDD 是多少？

参考AM335x的datasheet第五章：如果是默认状态OPP100的话，VDD_ CORE是1.1V (+/- 4%)，也就是应该在1.056V到1.144V之间。

如果你想测试的话，建议在AM335x芯片侧离VDD_CORE比较近的去耦电容上面进行测量。（不要在TPS65217侧。）示波器测量比较容易看出来问题，用1.056V作为触发电平，抓取是否有波形跌落到1.056V以下。

秦工, Steven:

        有个问题请教下： 

        我将nEvn.txt 中的command line修改下，将mem=512M修改成mem=384M, 之前的死机现象不出现了。能否帮忙分析下，这之间是否有关连？

你的板上内存是多大的？

芯片是256M * 16bit, 也就是512Mbyte

秦工，Steven:

          DDR3的配制核对了，应该没有问题，write leveling也做过了，通过，并将值写入程序。进行u-boot中的mtest进行内存测试，也没有问题。做死机现象还是存在，而且基本都打出同样的log（都是与omaplfb pvrsrvkm相关）。 请帮忙进一步分析一下，是否是软件问题？

孟工，

  1. 再确认下，是不是在mem=384的情况下，就没有您附上的log中提到的问题？

   2. 如果是，请上传您所计算DDR相关寄存器的两个excel和ddr的spec，我们一起来检查下。

谢谢！

我现在得到的参数是：

上面是303M的参数，400M的参数如下：

秦工：

     经测试，应该不是mem=384M修改后，才不出现此问题。而是用303M(DDR3的速率)跑才不出现此问题。

    但303M跑，HWRecoveryResetSGX还是会有。
