prinf下载到28335的FLASH中，不能打印

下载到flash，cmd文件有是否更改为flash的？

使用console可以输出数据吗？

仿真的时候也是用28335.cmd,下载的时候也是28335.cmd,

int myprintf1(const char *fmt,...)
{
int i = 0;
va_list args;
unsigned int n;
char buffer[128];
va_start(args,fmt);
n = vsprintf(buffer,fmt,args);
for(i = 0;i < n;i ++)
{
SendChar(buffer[i]);//通过串口发送字符
}
va_end(args);
return n;
}
int SendChar (int ch)
{
SciaRegs.SCITXBUF = ch;
while(SciaRegs.SCICTL2.bit.TXRDY==0);
//while (SciaRegs.SCIFFTX.bit.TXFFST != 0) {}
//SciaRegs.SCITXBUF=ch;
return ch;
}打印程序

仿真应该是借助仿真器的一路串口打出的。烧写完肯定不能打印

不是我呀，我从DSP引出来一路串口，作为调试用
