我正在使用RX62N R5F562N8BDFP（如果我很好地读取小芯片）。
我也在芯片上使用Micrium RTOS。
所以我使用的代码是读取SystemSettings，如果SystemSettings可用则调试。
如果micro-SD卡上没有SystemSettings，它会自行写入。
奇怪的是，当我评论调试部分时，它始终有效。今天早上我没有评论它并且它有效。一旦。之后，它只是不起作用，它只写一个调试文件的一部分。 ：/
这是我正在使用的代码，希望有人知道可能导致这种不稳定代码的原因。
可能部分不完整，但这就是它的作用。另一项任务（代码未发布）在消息堆栈上为此任务发布消息。
此任务读取并解密并执行操作。
这是很多代码，希望一切都很清楚..

编辑（wildplasser评论）： 我已经更改了一些遵循wildplassers指令的代码，尽管它仍然不起作用：/ 这是更新的代码，因此您有更好的主意。顺便说一下，我在log.c类中全局声明了init_LOG（）中使用的变量（其中Debug_LOG和Error_LOG是）。
