TI中文支持网Part Number:TMS570LC4357-EPOther Parts Discussed in Thread:TMS570LC4357
想利用EMIF通信方式让TMS570LC4357和FPGA进行通信，MCU的应用程序放在FPGA挂载的片外SDRAM上，MCU上电后直接在SDRAM（FPGA的）里运行应用程序。应该怎么操作呢？
我查阅了下资料，可以修改CMD文件，定义好应用程序的起始地址，这个地址是填SDRAM的吗？
我在bootloader里使能EMIF总线后，还需要做什么操作吗？

Yale Li：
我已经询问了相关工程师：

刚刚看到工程师回复了。还有个问题，如果我想操作SRAM，不用SDRAM了，也是一样的操作吗。？

Yale Li：
好的，我跟进过去了

Yale Li：
This device doesn't support booting from SRAM.
The device should boot from flash, and bootloader can upload the application to flash through DCAN, UART, SPI, Ethrenet etc.
If you'd like to execute the code in SRAM, you need to copy the code from flash to external SRAM. The SRAM has to be configured as normal memory type. Instructions cannot be executed from regions with Device or Strongly-Ordered memory type attributes.
