This works perfectly, I have run RAM tests for weeks and weeks, all checks out fine. But, if I place the non-cacheable area in the HyperRAM, things go downhill quickly...I get hardfaults (and sometimes debugger "dies" when debugging). I have been working with this for som...

My target doesn't have external RAM, and my DTC and ITC are not enough for my project, so I have to use OCRAM, my goal is to configure all OCRAM into non-cacheable, but when I change the memory configuration flags in the functions, it ends up in hard fault. Is this possibl...
目前缓存基本上都是采用SRAM存储器,SRAM是英文StaticRAM的缩写,它是一种具有静志存取功能的存储器,不需要刷新电路即能保存它内部存储的数据。不像DRAM内存那样需要刷新电路,每隔一段时间,固定要对DRAM刷新充电一次,否则内部的数据即会消失,因此SRAM具有较高的性能,但是SRAM也有它的缺点,即它的集成度较低,相同容量的...

I have a system with a RT1064 and HyperRAM (same chip as EVK). This works perfectly, I have run RAM tests for weeks and weeks, all checks out fine.

Someone took the original MPC5744 startup code (found in the example projects files in S32DS) and added a section to the memory map @ 0x40000000 (start of System RAM) and called it ".datanocache". Then they put various data objects there. However, I can't find any way that thi...
