带看门狗或进入低功耗的程序再次烧录失败问题【已解决】

armfly · 发表于 2020-6-20 18:46:59

客户反映烧录失败问题，如果已烧写带看门狗的程序，则会烧录失败。
问题现象描述：
1、如果不接硬件RESET口线，J-LINK可以烧录，但是ST-LINK无法识别到芯片。H7-TOOL可以识别但是无法正常烧录
2、如果接了硬件RESET口线。J-LINK和ST-LINK均可以烧录。H7-TOOL启用硬件复位模式，部分芯片比如STM32F103可以烧录，STM32F407不能烧录。
3、如果芯片是空的或者已有程序但是没启用看门狗，H7-TOOL无论软件复位还是硬件复位模式，都可以正常烧录。
4、分析ST提供的FLM算法文件, 在擦除、编程、校验函数中均有喂狗指令。执行FLM的init初始化函数时，如果ption bytes启用了硬件看门狗，则修改看门狗时钟分频
让CPU看门狗周期为最大。因为硬件看门狗不掉电复位是关闭不了的。缺省是软件看门狗，复位后会关闭。

这几天我将分析下J-LINK的处理机制。特别是SWD接口初始化部分，最好能自动尝试两种复位机制。

记得 swd可以让mcu hlod住不运行

STM32的独立看门狗和窗口看门狗停止计数有个寄存器的，这个是专门给调试准备的，就怕用户的应用程序有开独立看门狗，专门准备的这个，所有STM32系列貌似都有。
看看能不能派上用场：

TOOL可以自己轮番测试硬件或者软件复位非常有意义，提升TOOL自动化效率，用户就不需要为复位问题操心了。

再次确认了下板子状态和问题现象：
1、STM32F407目标板无硬件RESET，未设置读保护。启用了看门狗（不清楚是独立看门狗还是窗口看门狗）。
2、ST-LINK无法应对无硬件RESET的情况，但是加上硬件RESET就可以成功连接。
3、J-LINK不用硬件复位也可以成功连接。

为此抓取了J-LINK Connect STM32F407的波形，解码数据如下：

研究的好细致啊。。。。都是专业人士用的。
调试命令接口应该是arm公司统一定义的吧？

调试内核是ARM整的。

事情反转。第3次确认。如果没有硬件RESET口线，J-Link也无法connect。
这次测试是将目标板断电并完全放电完毕再上电进行测试。前2次估计是没完全放电完毕。

通过观察RESET波形。发现关闭调试期间看门狗的语句是在RESET = 0电平期间执行。关闭了以后再释放复位口线。这样CPU才能在DEBUG状态完全关闭看门狗。

这说明了SWD烧录接口加上硬件RESET口的必要性。如果你的程序开启了看门狗或启用了低功耗停机等模式。
那么再次烧录时，可能需要硬件RESET口线参与才能再次烧录。
为啥是可能，我想如果只是开启独立看门狗并且周期很长也许没事，因为FLM算法中也有喂狗动作。
当然如果程序启用了窗口看门狗只能在特定周期内喂狗，那FLM算法中的喂狗必要导致错误的喂狗动作。

如果程序上电就进入低功耗停机模式估计对烧录也是有影响的。

应该就是这样的，公司的好多产品都是4线的下载口，程序内部添加了独立看门狗，超时都在1以上，所以平时下载固件没问题，但是一些低功耗的会睡眠的产品就不行了，必须短接下复位引脚才能正常下载。我记得当时我发现的一个规律是用J-flash下载的时候先连接，在执行下载就可以下载了，而不是直接F7下载。当然这个有待考证。

如果情况是这样的话，那就有一个STLINK和JLINK无法下载时（特别是STLINK，JLINK也有，但是非常少），弹出Invalid Rom Table的解决思路，他的解决办法就是保持under reset，使用硬件复位才可以解决。
这个是MDK专门提供的一种解决思路：

模仿J-Link的操作步骤，终于烧录成功了。虽然有些寄存器的含义还不太懂，但是不影响我完成这个功能了。
后面就是要整理代码，优化框架，将对CPU的特殊处理代码抽取到lua文件中。
因为每个CPU关停看门狗和低功耗状态开启时钟的操作方式不同。适配所有的cpu，这部分工作量太大，需要阅读芯片手册每款或每个系列的CPU手册。
几个关键点：
1、这种状态出现，只有在RESET = 0时，才能hold cpu
2、判断这种状态的方法：读NVIC_CPUID寄存器，0值表示异常. (不知道其他CPU是否这样）
3、只有识别出这种情况后才需要进行解锁处理。如果没问题按常规流程走。

本想简化下 InitUnderReset（）函数，只写寄存器，不读寄存器，因为读寄存器需要区分单路模式和4路模式。等我将全部的芯片lua脚本都修改完毕，测试发现写入成功，但是后续的代码会执行异常。原因未知。
