CH32V307VCT6开浮点运算就会报错，编译就报错，工程就是IDE生成的，没改过，只要改属性开浮点运算就报错，怎么解决，还是不是这样开的吗，如下图

而且我怎么发不了贴了？那在这继续问吧

我有两个超大常量数组，直接用const修饰存在flash里flash 288k很快就满了，我看flash好像有480k的大小可以使用，怎么把这个超大常量数组存进去，还有这个flash和ram可以一个大一个小，能否具体讲解一下，flash大小改了和那480k又是什么

您好 ，下图为在MRS184新建内部CH32V307工程，打开硬件浮点的配置和编译结果，编译无错。你可以将报错信息和工程贴上来或者将报错工程发送到邮箱yangy@wch.cn

那我感觉应该是我这边的问题，你看看他提示的报错要怎么解决
