Hi, @jeremyzhou 

RT1064的FlexRAM可否实现OCRAM=0,DTCM=256KB, ITCM=256KB?

我在我的工程中已经实现了OCRAM=128KB,DTCM=128KB, ITCM=256KB,但是我试图实现OCRAM=0时,出现了以下问题:

我的配置如下:

1、FlexRAM配置

2、  ld文件配置

3、MPU配置

我尝试把Region7注释掉,并没有什么效果

以上的问题可能是因为什么引起的呢?RT1064是否支持配置OCRAM=0?(只能本身的512KB OCRAM)

Hi,
非常感谢使用NXP产品,很高兴为你提供技术支持!
首先,对于你的问题,我的回答是可以实现的,其次,
建议参考此篇经验分享来完成FlexRAM重新配置:
https://www.nxpic.org.cn/module/forum/thread-619452-1-1.html。
跟着,在ld文件配置中,你不需要直接更改ld文件,上述经验分享会告诉你怎么修改RAM的空间配置,最后,Region7 是需要注释掉的。
Have a great day,
TIC

你好,链接已经失效了。 另外,我是直接使用ld文件的,并没有使用界面配置的方式,这种情况是需要改ld文件的吧?
