TMS320C6678: 6678

目前编写了一个代码，通过核0对其他核发起局部复位，网络接收BIN并存放到指定的位置，再通过IPC信号唤醒其他核。

bin放在L2SRAM时可以正常运行，但是放在DDR3时产生异常第一次唤醒其他核后跑飞，第二次后又能正常。

memset(pBuf, 0, 13);
bytes = (int)recv(connfd, (void *)pBuf, 9, 0);  //接收bin程序入口_c_int00地址
if(bytes != 8) {
	uart_printf("File Head Error 1!bytes: %d!\n", bytes);
	goto leave;
}
Entry_Address = strtohex(pBuf, 8);
memset(pBuf, 0, 13);
bytes = (int)recv(connfd, (void *)pBuf, 9, 0); //接收存放bin文件起始地址
if(bytes != 8) {
    uart_printf("File Head Error 2!bytes: %d!\n", bytes);
    goto leave;
}
WriteAddr = (unsigned int*)strtohex(pBuf, 8);
memset(pBuf, 0, 13);
bytes = (int)recv(connfd, (void *)pBuf, 2, 0); //ignore standard header
if(bytes != 1) {
	uart_printf("File Head Error 3!bytes: %d!  %s\n", bytes, pBuf);
	goto leave;
}
corenum = pBuf[0] - 0x30;  //接收需要替换代码的核号
uart_printf("%x %x %d\n", Entry_Address, (unsigned int)WriteAddr, corenum);

while (1) {
	memset(pBuf, 0, 13);
	bytes = recv(connfd, pBuf, 4, 0);
	if (bytes <= 0) {
	    break;
	}

	*WriteAddr = littleToBig(pBuf);
	WriteAddr++;
