GD32F407ZG系列内存问题

justdying

问题：
GD32F407ZG系列内存问题，本来是192K的，但是我程序内存用到128K左右，继续申请就报错了。
手册写的：
          GD32F407 - ARM Cortex-M4 Core
          Frequency up to 200 MHz
          Flash access zero wait state
          Single-cycle multiplier and hardware divider

        Memories
          Flash size from 512KB to 3072 KB
          SRAM size is 192 KB with HW parity checking
          30KB ISP loader ROM
在keilMDK里面，我编译后

最大只能到128K左右吗？
我在程序中多加1K的数组就报内存不足了，想问下剩下的内存去哪了？？

，解决了 ，发现这个勾选上就行了，这个勾选会影响功耗吗？为什么作为一个可选项呢？

justdying

勾选之后程序不跑了？？

是呢

这个和ST的一样的哈，多看看硬汉大哥的相关帖子哈。

大概知道了  是CCM内存

tsetse

64K 部分不能用 DMA，只允许 D-BUS 访问

ST是这样的，GD也是这样的？

对于这种不连续的多块内存，我一般都直接分配给操作系统（比如使用FreeRTOS的heap5，ThreadX的块内存等等）。

IRAM2 没勾选
内存池定义的时候增加__attribute__((at(0X10000000)) 字段说明就正常了

[C] 纯文本查看 复制代码

//内存池(32字节对齐)
__align(32) u8 mem1base[MEM1_MAX_SIZE];													//内部SRAM内存池
//内存管理表
u16 mem1mapbase[MEM1_ALLOC_TABLE_SIZE] __attribute__((at(0X10000000)));					//内部CCM内存池;		

GD也是一样的

这种骚操作，我觉得GD真没必要也去兼容ST，客户经常在这里入坑。

分享个玩法，方便大家使用

像使用内部SRAM一样定义使用SDRAM和CCM RAM，可以随意定义到指定的RAM区域且无需具体地址
