PIC24FJ256GA106上的RCON频繁板复位

嗨，我正在使用，OpenPICUS，一个基于PIC24FJ256GA106的SOM，我面临着不可预测的和频繁的板复位，我正在探索几个解决方案来调试根本原因；微控制器附带一个预安装的串行引导加载程序和一个基于FiReTOS的示例固件，其中包括一个HTTP服务器。我用这个例子作为一个框架来实现我的固件和MPLAB C30来构建它（我保留了OpenPICUS开发人员所做的相同的编译器选择）。除此之外，我试着做的是保存并重置RCON寄存器，然后在每个板重置之后通过HTTP请求读取它。虽然我能正确地读取这些情况下的RCON值：PUPUP RESET COSTESSAVE＝3（BOR + Por位[位0和1 ]）MCLR复位-RESET DeaseSave= 128（MCLR位[位7 ]）复位指令REST DeaseSave= 64（SWR比特[BI）]T 6））但是当我意想不到的重置时，我所拥有的是ReesteTeaSea= 0，这意味着RCON位都是零。我缺少什么？有没有更好的方法来调试这个问题？

    Hi,
i'm using, OpenPicus, a PIC24FJ256GA106 based SOM and I'm facing unpredictable and frequent board resets and I'm exploring several solutions to debug what is the root cause; the Microcontroller comes with a serial bootloader pre-installed and a FreeRTOS based example firmware, that includes an HTTP Server. I used this example as a skeleton to implement my firmware and MPLAB C30 to build it (I kept the same compiler choice done by the developers of OpenPICUS).
Besides those premises what i've tried to do is to save and then reset RCON register and then read it via an HTTP request after each board reset:


    resetCauseSave = (unsigned int) RCON;
    RCONbits.POR = 0;
    RCONbits.BOR = 0;

while i can read correctly RCON values in those situations:
