浩卢 — Thu, 24 Mar 2016 06:31:37 GMT

I have flashed i.mx6q with MFGTOOL and it stoped at jump to os image.But after heated to the board，I can flashed succeed.I have tested 10 i.mx6q boards like this.

Someone can hlep me please?

Hi ,

Are all your board like this? Here you design your board yourself, are you refer to the design of our reference board?

Have a nice day

Best Regards

Dan

Hello,

Here if you do not heated the board, it stopped at jump to os image?

Best Regards

sorry. I have‘t solved yet.

In your design have you changed the DDR, or do any changes? Or use the default one in our reference board?

Have a nice day

我这里帮你确认了一下，你这里应该是炉温不够引起的，或者是DDR3颗粒有氧化的可能。建议你换内存颗粒试一下。或者重新焊接一下DDR3颗粒。

或者你也可以用BGA焊台，重新给DDR3再次加热。

希望如上可以对你有帮助。

Have a nice day

Dan Wang 你好

问题已经解决了，我还疑跟板材有一定的关系，这次用的是IT-180。

我们可以分析一下问题，10块样板，在加热DDR的情况下，都能烧写成功，并且可以长时间稳定的运行，那么我认为硬件上本身不存在什么设计缺陷；

MFG_TOOLS的烧写原理：通过USB下载linux的uboot，kernel，filesystem来启动一个简单的linux系统，在linux系统下，通过dd命令来进行烧写，在不加热的情况下，经过分析log文件，能够确定uboot已经load下去了，但是没有能正常启动，那么能够证明，烧写用的uboot和我自己编译的uboot，肯定是不一样的，所以我参考自己编译的uboot的flash.S文件，修改了烧写用的uboot的falsh.S的参数，后来就可以正常烧写了。

问题总结，从我的情况看来，我认为FSL在烧写使用的uboot的上，存在一定的不合理性，既然自己编译使用的uboot的能够正常启动板子，那么，烧写使用的uboot为什么要设计不一样的参数，目的又是什么？

浩卢：

您好！我也是同样的问题，现在还没有解决，你是在更换了板材后才烧写成功，还是不更换板材，只修改head.s就可以烧写成功呢？修改的head.s是涉及到哪些参数呢，只需要和自己的uboot一样就可以了么？

期待你的回复！谢谢！

尝试修改一下这些参数。

这些参数是怎么得到的？是根据你的board校准的还是其他方式？

I have met the same problem twice.

My PC were down at the same time the board crashed when using the MFG_TOOL.

When the PC and board were restart, the second trail would be success.
