[help]: slow big core #54

Closed yf13 closed 7 months ago

Help

When NuttX running on big core, test app getprime takes about 11158ms, while it took only 308ms on little core.

I guess some settings for big core is missing (e.g. cache) here, can you teach where such settings can be found in K230_SDK source tree?

I saw them in opensbi/platform/kendryte/fpgac908/platform.c, will reopen if they are not enough later.
