我才发现原来memcpy并不是直接使用调用的，编译器还分了单字节复制和4字节复制的方式 rt_memcpy_v6 rt...
此时CPU发出的就是物理地址,直达硬件和内存// 为了加速一些循环操作,例如将内核复制到DDR中的memcpy,可以开启ICACHEmrc p15,0,r0,c1,c0,0// M bit = 0, MMU disable:bic r0,#0x1// I bit = 1, enable icacheorr r0,#0x1000mcr p15,0,r0,c1,c0,0// ...
Fixed bugs on LWP kill; Fixed exit(2) and added exit_group(2); Fixed rt_memcpy to lwp_memcpy in smart source; Fixed cmd_kill (Fix cmd_kill). Added fops for dfs_v2 and fixed warning for eventfd_write and eventfd_read after dfs_v1 changes. Cumulative updates of lwip and lwp. libc...

Use rt_memcpy rt_memset instead of memcpy memset Fixed AT component in CLI mode, the command input is too long, resulting in the array out of bounds [example] Remove RT_USING_TC Fix armclang Cpp11 memory leak and compilation warning issues Improve and add comments in examples/network/...
Add recessive RT_USING_ASM_MEMCPY definition to Kconfig Add RT_PRINTF_LONGLONG option to Kconfig, not selected by default Clear support for RT_PRINTF_LONGLONG in kservice.c Fix RT_PRINTF_LONGLONG is supported by default in 64-bit mode Solve the problem that FINSH cannot respond to serial ...
