Hi engineers,
We want to reduce the startup time of SBL, so the focus is on OSPI-CLK, OSPI-DMA, Dcache and Icache. TI's currently released SDK-Does SBL support OSPI to use DMA and Cache? Please tell me the SDK version that supports the above functions. I will conduct a test to see if DMA and Cache can reduce the startup time to meet the needs of our project. Thank you!
Nancy Wang：
请问您使用的SDK版本是什么?从OSPI启动的时间测下来是多少？
,
ziqian li：
SDK 7.2，我们测下来要300ms左右

Nancy Wang：
请问是RTOS还是LINUX?我需要咨询相关工程师再给您回复。

ziqian li：
sbl工程中应该没有操作系统

Nancy Wang：
我默认您使用的是PSDK-RTOS,请关注以下英文贴的回复：
