在C6657多核运行，串口打印乱码，程序通过PCIE加载到DDR3，多核启动思路参考pcieboot_helloc.c：代码和现象如下
代码如下：
Int main()
{
// DEVICE_REG32_W(BOOT_MAGIC_ADDR(0), BOOT_MAGIC_NUMBER);
#if 1
int nthreads, tid;
#pragma omp parallel
{
platform_write("[C66xx_%d] Hello World from thread = %d\n",DNUM,omp_get_thread_num());
}
/* Fork a team of threads giving them their own copies of variables */
#pragma omp parallel private(nthreads, tid)
{
/* Obtain thread number */
tid = omp_get_thread_num();
platform_write("[C66xx_%d] Hello World from thread = %d\n",DNUM, tid);
/* Only master thread does this */
if (tid == 0)
{
nthreads = omp_get_num_threads();
platform_write("[C66xx_%d] Number of threads = %d\n", DNUM,nthreads);
}
} /* All threads join master thread and disband */
#endif
platform_write("[C66xx_%d] BIOS_start\n",DNUM);
BIOS_start(); /* does not return */
return(0);
}
现象如下：
o[CC666xx6_x0x]_ Hello1 ]W orld froHm threaedl l=o 0W
rld from thread = 1
[CC666xx_06]x Hello Worxld f_r1o]m Htehlrleoa dW o=r l0d
tf[C66xxr_o0m] tNhurmebaedr =o f1
hreads = 2
[C66xx_0] BIOS_start
这并行指令core0和core1通过串口打印出来都重叠在一起，根本看不清，麻烦分析下是什么原因
