错误看起来是rt-thread其它定义升级了，但是arm926对应的接口函数没有同步升级造成的。 rt-thread\libcpu\arm\arm926\cpuport.c:140:11: note: in expansion of macro 'rt_hw_cpu_dcache_status' 能加一个nuvoton bsp的action吗？这样就能使得自动测试能覆盖arm926

Try another multicore example from [here](https://github.com/earlephilhower/arduino-pico/blob/master/libraries/rp2040/examples/Multicore/Multicore.ino). But the core1 without any output. Reference [Doc](https://arduino-pico.readthedocs.io/en/latest/multicore.html).
