如何正确跳转到地址0x602D的Bootloader入口点

菲利克斯，
 
GoAddress不指向BOOTLOADER_ADDR，而且它未初始化。
尝试使用MainUserApplication（）而不是GoAddress（）;
 
祝你好运！



以下为原文







Felix,

GoAddress does not point to BOOTLOADER_ADDR,moreover, it is not initialized.
Try MainUserApplication() instead of GoAddress();  

Good luck!

谢谢Yevpator，
 
 
那么现在微观似乎跳了但是我没有成功进入引导程序。引导程序没有答案，但我还在努力......
当我最终设法使用引导程序时，我会给你一个更新。

Thank you Yevpator,


Well now the micro seems to jump but I did not succeed to enter the bootloader. No answer from bootloader but I'm still trying...  
I'll give you an update when I will finaly manage to use the bootloader.

嗨菲利克斯，
 
据我了解，您尝试激活内置STM8引导加载程序。最近我设法做到了。请注意，此系列中的不同MCU具有不同的Boot-loader入口地址。因此，请检查您使用的MCU的正确地址。
我也明白你想绕过ROP检查，不是吗？我的意思是你试图在测试ROP字节后跳转到通常Bootloader应该出现的地步。
但是还要检查Option字节中是否启用了Bootloader。默认值为disable：0000。要启用该功能，需要在相应的Option字节中写入55AA。如果你没有启用这些选项字节，那么只有当设备是处女时才会运行Bootloader，而这不是你的情况，因为你正在编写程序......
祝你好运 ！

Hi Felix,

As I understand, you try to activate the build-in STM8 bootloader. Recently I managed to do that. Be aware that different MCU in this family have different entry addresses of the Boot-loader. So check what is the correct address for MCU you use.
I also understand that you want to bypass the ROP checking, don't you ? I mean that you try to jump to the point where usually Bootloader should come after the ROP byte is tested.
But check also if Bootloader is enabled in Option bytes. The default is disable : 0000. To enable that you need to write 55AA in the appropriate Option bytes. If you didn't enable these option bytes, the Bootloader would run only if the device is virgin, and this is not your case, since you're writing a program...
Good luck !

菲利克斯。
 
 
你有没有设法解决这个问题？如果是的话，请您在此分享您的结果？
 
我问，因为我现在有同样的问题......
 
 
谢谢。

Hi Felix.


Did you manage to solve the problem ? If so, would you please share here your results ?

I'm asking, since I have the same problem now...


Thanks.

大家好，
 
 
我必须推迟这项工作，因为我有其他问题需要处理。一旦我回到bootloader，我将分享我的结果。
 
非常感谢

Hi all,


I have to postpone this work since I have others issues to deal with. As soon as I come back to bootloader I will share my results.

Many thanks

菲利克斯，
 
 
我设法做到了。
在跳转到Bootloader条目之前，您应该释放Bootloader所需的所有外围设备。由于没有提供Bootloader使用外设的列表，当我想启动Bootloader时，我在数据EEPROM中放置了一个标签（标志），然后期待POR。在POR之后，我检查此标志是否发出信号。如果是，那我跳。也就是说，如果在POR之后立即跳转到Bootloader，则不必关心释放外设。
请注意，您有1秒的时间来启动与Bootloader的通信，之后Bootloader会跳回应用程序。
 
希望您发现此信息有用。
祝你好运 ！



以下为原文





Felix,


I managed to do that.
Before you jump to the Bootloader entry you should release all the peripheral essential for Bootloader. Since no list with the peripherals being used by Bootloader is provided, when I want to start Bootloader, I put a label(flag) in the Data EEPROM and then expect for POR. After POR, I check if this flag is signalling. If it is, then I jump. That is to say, if you jump to the Bootloader immediately after POR, you don't have to take care about releasing peripherals.
Please pay attention that you have 1 sec for starting communication with bootloader, afterwards Bootloader jumps back to the application program.

Hope you find this information helpful.
Good luck !

嗨Yevpator，
 
 
现在它完美无缺。
你的最后评论对我非常有帮助，非常感谢！

Hi Yevpator,


Now it works perfectly.  
Your last comment was very helpfull to me, many thanks!

It's my pleasure.

嗨，
 
 
 你能分享你的代码吗？我尝试做但是当ROP很难进入时无法进入bootloader
 
 非常感谢

Hi,


Can you share your code? I try to do but can not enter bootloader when ROP eneble

Thanks very much
