你好！
我一直在尝试发送虚拟802.15.4帧、但遗憾的是、器件在运行时卡住：
RF_EventMask ev = RF_runCmd(rfHandle, (RF_Op*)&RF_cmdIeeeTx_ieee154_0, RF_PriorityNormal, NULL, 0);
更具体地说、是在线路上的 RF_PendCmd
/* Wait for semaphore */ SemaphoreP_pend(&h->state.semSync, SemaphoreP_WAIT_FOREVER);
下面是我的完整代码：

if(rfHandle == NULL){
print_string("GOT NULL rfHANDLE!!!");
}
int st = RF_postCmd(rfHandle, (RF_Op*) &RF_cmdFs_ieee154_0, RF_PriorityNormal, NULL, 0);
if(st < 0){
print_string("FS init failed");
}
GPIO_write(CONFIG_GPIO_0, CONFIG_GPIO_LED_ON);
print_string("Init finished, starting tx\r\n");
while(1){
//send packet
fill_packet();
RF_EventMask ev = RF_runCmd(rfHandle, (RF_Op*)&RF_cmdIeeeTx_ieee154_0, RF_PriorityNormal, NULL, 0);
print_string("PACKET SENT, STATUS:\r\n");
print_rf_event_mask(ev);
uint32_t cmdStatus = ((volatile RF_Op*)&RF_cmdIeeeTx_ieee154_0)->status;
print_rf_prop(cmdStatus);
RF_yield(rfHandle);
usleep(PACKET_INTERVAL);
}
return NULL;
}
有什么想法吗？ 我尝试在 TI-RTOS 下运行它、以防出现这种情况、但目前还不幸运。
非常感谢！
