EZBL Bootloader从应用程序返回并继续引导加载程序任务

在你的应用程序中，“主”功能是否退出了？不应该！“返回引导程序”是否通过重置发生？也许是看门狗超时！最佳选择

    Hi
 
In your application, does the "main" function ever exits?
It shouldn't!
The "return to bootloader" does it happen via a RESET?
Maybe a watchdog timeout!

在MPLABX中，可以用加载程序调试这一点。这意味着在两个应用程序中都有调试信息的组合应用程序。然后，您可以同时进入Bootloader并在其中同时使用具有调试信息的应用程序。我通常将应用程序添加到Bootloader中。



      以下为原文

    You can debug this easier with loadables in MPLABX. This means that you make a combined application with debug info in both. Then you can step into both the bootloader and continue in to the application with debug info in both. I usually add the application as a loadable to the bootloader.

在我的应用程序中，我尝试使用ExxiAppNo.EZBLYBASE.CODE.NEXIXAPPUNONEZBLYBASE代码，每100毫秒闪烁一个LED，在Bootloader中，我闪烁另一个LED。当我引导Bootloader和应用程序时，首先发生的是Bootloader运行，闪烁Bootloader LED然后进入应用闪烁四次LED应用。然后再次启动BooLoad然后应用程序…这件事就像一个环。根据文件，我在AddieDeBLIX集成中，在目录和MPLABX项目窗口中生成文件。所以，为什么这个引导加载程序-& gt；应用程序& gt；引导加载程序？& gt；应用程序&…循环发生了吗？在应用中，我不使用WDT。我眨眼了一会儿（1）。



      以下为原文

    Instead of my application, I tried to use ex_app_non_ezbl_base code. 
In ex_app_non_ezbl_base code, there is a led that blinks for every 100 ms. In bootloader, I blink another led once.
 
When I program bootloader and application what happens is first the bootloader runs, blinks bootloader LED then enters application blinks application led four times. Then once again bootloader then application... This thing happens like a loop.
 
In ex_app_non_ezbl_base code, according to the document, I added ezbl_integration and Make file in directory and in MPLABX project window. 
 
So, Why is this bootloader-->application-->bootloader-->application-->.... loop happening? 
 
In Application I am not using WDT. I blink LED in a while(1).
 

 
#include
#define FCY 4000000 // Execution speed for __delay_us()/__delay_ms() macros
#include

int main(void)
{
ANSAbits.ANSA1 = 0;
TRISAbits.TRISA1 = 0;

while(1)
{
LATAbits.LATA1 = 1;
__delay_ms(100);
LATAbits.LATA1 = 0;
__delay_ms(100);
}
}
 

 

HII将搜索：伪重置，可能来自噪声，或BOR。你有MCLR引脚启用吗？它是如何连接的？-引导加载程序是如何激活的？有没有可能由于连接不良而激活？-意外中断。您的代码不能启用任何中断，但可能引导程序留下一些定时器、EUSAT或其他IRQ源激活，而您的代码不与此相关联。



      以下为原文

    Hi
 
I would search for:
 
- Spurious RESET, maybe from noise, or BOR. Do you have the MCLR pin enabled? How is it connected?
- How is the bootloader activated? Any chance its beeing activated by a poor connection to a pin?
- Unexpected interrupt. Your code doesn't enable any interrupt, but maybe the bootloader leaves some timer, EUSART or other IRQ source active and your code ins't copping with it.
