rk3588启动偶尔会启动失败,接上串口,对比正常启动和启动失败的输出信息,发现启动失败时
串口输入会有如下信息,当出现下面信息时(CPU1-CPU7),启动一定会失败,请帮助分析一下原因
[ 1.826224] smp: Bringing up secondary CPUs ... I/TC: Secondary CPU 1 initializing I/TC: Secondary CPU 1 switching to normal world boot I/TC: Secondary CPU 2 initializing I/TC: Secondary CPU 2 switching to normal world boot I/TC: Secondary CPU 3 initializing I/TC: Secondary CPU 3 switching to normal world boot I/TC: Secondary CPU 4 initializing I/TC: Secondary CPU 4 switching to normal world boot I/TC: Secondary CPU 5 initializing I/TC: Secondary CPU 5 switching to normal world boot I/TC: Secondary CPU 6 initializing I/TC: Secondary CPU 6 switching to normal world boot I/TC: Secondary CPU 7 initializing I/TC: Secondary CPU 7 switching to normal world boot
正常启动时只有 [ 1.826224] smp: Bringing up secondary CPUs ... 一行输出,且在这之前还有两处输出是异常启动没有的 [ 0.802638] pcpu-alloc: s88296 r8192 d30488 u126976 alloc=31*4096 [ 0.802645] pcpu-alloc: [0] 0 [0] 1 [0] 2 [0] 3 [0] 4 [0] 5 [0] 6 [0] 7
